A polar graph is a two-dimensional coordinate system whose points are defined by the equation R = f(θ), where R is the radial length from the vertex of the graph to point and θ is the angle between the horizontal axis and the point. The shape of the polar coordinate system is circular so polar points are more easily represented with circular measurements. Calculating polar graphs require the plotting of multiple points on the coordinate plane in order to determine the shape of the graph.
An angle is a measurement of turn. Angles consist of two straight arms that join together at a point called the vertex. The distance between the arms near the vertex represents the measurement of the angle. Angles are frequently used in geometry. The most common example of the use of an angle is in the definition of a right triangle, which must contain one 90 degree angle within and the other two angles must also add up to 90 degrees, for a total internal angle measurement of 180 degrees.
A polar curve is a curve expressed using polar coordinates. Unlike Cartesian coordinate points that are expressed as a horizontal and vertical distance from a point, polar coordinates are expressed in terms of angles and distance between points. The polar plane is circular and measured in degrees or, more typically, radians. The polar coordinate of a point on the curve is represented by a radial and an angular component. The radial component indicates the distance of the point from an origin point. The angular component indicates the necessary angle and direction needed to reach the point from the horizontal polar…
Imaginary circles of latitude divide the globe vertically; circles of longitude divide the globe horizontally. Each circle contains 360 degrees. Like the hours of a day, each of those degrees contains 60 minutes, and each minute 60 seconds. A nautical mile, in fact, represents a distance of one minute of one degree of latitude, and there are 60 nautical miles in a degree of latitude. If you are not using a degrees, minutes, seconds (DMS) geographic coordinate system, you may be using a degree decimal system, which replaces minutes and seconds with a decimal number. To convert decimal degrees to…
As a measurement of heat, the British thermal unit (BTU) is defined as the amount of heat required to increase the temperature of one pint of water to one additional degree Fahrenheit. Since the Fahrenheit scale only measures the temperature and not the amount of heat needed to increase liquid temperature, you need a perform a simple conversion to determine the temperature required, in Fahrenheit, with respect to BTU.
Custom wheels, whether they're on your tractor or your car, come with bolt holes spaced a specific distance, called a bolt pattern. These measurements come in either metric or standard versions. Sometimes, you know the metric bolt pattern of your wheels, but you only know the standard bolt pattern on your vehicle, which puts you in a predicament. Without converting the metric pattern to standard inches, you won't know whether the wheels will fit. Solving the issue takes some basic math.
Lathe digital readouts are used by woodworkers to determine where they should be shaping the wood to get just the right look. The readout's X, or cross-slide, axis, in addition to the Z, or lead screw, axis, ensure that you don't have to count out each hand wheel revolution of the lathe, or calculate information in your head while trying to work. Connecting your lathe digital readout to your woodworking machine keeps your eyes on your project.
The building industry relies on spirit levels to see if surfaces are level. This device consists of an air bubble trapped within a clear fluid. The spirit level is placed upon a surface, and if the bubble lies between calibration marks, the surface is level. Some building applications require a surface to be at a set angle rather than being level, and in order to do this, a digital angle gauge often is used. These usually display the angle in units of degree, but for trigonometric applications, it often can be useful to measure these angles in radians instead.
We use degrees of latitude and longitude to pinpoint any location on the planet. The Earth is essentially a sphere rotating on an axis. This axis runs through the North and South poles. The equator is a line equidistant from these two poles; the equator is located at 0°, while the North Pole is at 90° N and the South Pole is at 90° S. Lines of latitude run parallel to the equator, between the North and South poles. Every location on Earth is given a specific degree of latitude, which can then be broken into minutes and seconds. In…
The radian is an angular unit of measurement. Also a ratio, a given number of radians is the arc length associated with a given plane angle divided by the radius of the circle. Therefore, 1 radian (180 degrees/Pi) is when an arc length of a circle defined by a subtended angle is equal to the circle's radius. Given this relationship, you can simply convert between degrees and radians. 1 radian = 180 degrees/Pi Pi=3.14...
Locations on the globe are typically measured in longitude and latitude. The equator is a line at zero latitude. The north and south poles are at 90 degrees north and south latitude, respectively. Latitude is usually measured in degrees, minutes and seconds. There are 60 minutes in a degree, and 60 seconds in a minute.
Percent grade and slope in degrees both indicate the amount that elevation changes over a certain distance, which determines how steep a hill or slope is. Percent grade denotes the percentage of change in the elevation--for example, if a hill rises 20 feet over a 100-foot distance, it has a 20 percent slope. The slope in degrees indicates the angle between the surface of a hill and level ground.
Latitude is a geographic coordinate that together with longitude describes a location on the earth's surface. The latitude is an angle and is measured in degrees, minutes and seconds -- 55 degrees, 12 minutes, 36 seconds, for example. For various calculations, you often need to express the latitude in the degree decimal form. Use a calculator or available online services to convert the latitude to degrees.
The Fahrenheit scale has been successfully adopted in the United States for measuring temperature. On that scale water freezes at 32 degrees and boils at 212 degrees. But almost all other countries in the world use Celsius degrees. Contrary to the Fahrenheit scale, water boils at 100 Celsius degrees and freezes at 0 Celsius. To convert 250 Fahrenheit to Celsius, use either an online temperature converter or make three simple mathematical operations on a calculator.
Distillation is the process used to purify or separate different components of a mixture. It has many uses, aside from producing alcohol, including making gasoline from oil, converting seawater into drinking water, manufacturing perfumes and turpentine, and making vitamins and other nutritional supplements like fish oils. There are several methods of distillation. Which one is used depends on the unique properties of the substance being distilled.
In geometry, a degree is the unit of angle measurement, equal to 1/360 of a circle. When measuring angles from the center of circle, degrees can also be expressed as radians. The radian measure of an angle is the ratio between the length of the arc opposite the angle and the radius of the circle. An arc is a portion of the circumference of a circle, so the arc length is defined as the length of that portion. By converting an angle’s degree measure to radian measure, you can find the arc length opposite a given angle, measured in a…
Sphagnum moss is a branch of the botanical division Bryophyta. It is renowned for its ability to thrive in environments generally unsuited to a great deal of plant life. It is found in many parts of the world where climatic conditions permit. Sphagnum moss plants consist of a single stem supporting compact arrangements of branches.
Temperature sensors are one part of a thermometer, gauge or temperature control device. Sensors detect changes in temperature, which the device then reads, calculates the change, converts it to degrees and displays it. Devices like thermostats act on the change by turning another device on or off to regulate the temperature being monitored. The materials temperature sensor devices are made of, and how they respond to temperature changes, determine their type.
Many people want to know how to convert Fahrenheit to Celsius, but don't know how to do this conversion. You can figure out the conversion in a matter of seconds with a calculator. It is just as easy to convert from Celsius to Fahrenheit; all you need to do is reverse the formula in order to make accurate calculations. With this formula, you will no longer need to estimate the conversion in your head.
Radians and degrees are two different units of measure for angles of a circle. It's commonly known that a whole circle is 360 degrees and a half circle is 180 degrees. Radians also measure angles, but they relate to the radius of a circle, which is a straight line from the center to the circle to anywhere on the circumference. One radian is the measure of an angle whose arc length is equal to the radius. Because the circumference of a circle is equal to 2πr (π being pi, which can be rounded to 3.14), and we know that a…
To simplify formulas, scientists, mathematicians and engineers measure angles in radians instead of degrees. Using radians, allows measurements to be expressed in terms of pi rather than a string of decimals.
In order to measure distances and locations on the Earth's surface, scientists use a system of imaginary lines called latitude and longitude. Longitude runs north and south and is used to measure distances that are east and west. Alternatively, latitude runs east and west and is used to measure distances that are north and south. Because of the Earth's curvature, lines of latitude are equidistant to each other (as opposed to the curved lines of longitude). As such, it is easy to convert latitude into miles.
Gypsum is a naturally occurring form of calcium sulfate, CaSO₄·2H₂O. It is used in the building trade for gypsum board, also called drywall, and is an ingredient in plaster of Paris. It is made of the elements calcium, sulfur, oxygen and hydrogen. The sulfur can be removed from the gypsum by a series of chemical steps including use of a heat, reducing agents and catalysts.
Latitude and longitude are measurements based on imaginary lines drawn around the Earth. Latitude values indicate a north/south measurement and longitude values indicate an east/west measurement. The values are given relative to starting points, which are the equator for latitude values and the Royal Observatory in Greenwich, England, for longitude values. Both measurements can be given in minutes/seconds notation or in decimal notation. In either notation form the information is the same, so that you can, for example, change latitude from degrees to decimals and vice versa.
If you have ever traveled in a foreign country, chances are that you have been confronted with the task of deciphering what the temperature really is outdoors. Almost all countries in the world use a Centigrade (also called Celsius) scale. The United States being the main place, where the Fahrenheit scale is used mainly for recording meteorological data. In all other scientific endeavors , the Centigrade scale is standard. For an explanation on how to convert Fahrenheit to Centigrade, continue with this article.
Brix is a measurement of the amount of sugar in a solution per weight of total solution. A solution that is 10 degrees Brix has 10 g of sugar per 100 g of solution, or if the solution is simply sugar and water, there are 90 g of water and 10 g of sugar. Brix is often used in winemaking to determine potential alcohol content of a wine.
