How to Convert Temperature from Celsius to Fahrenheit

In 1742, a Swedish astronomer named Anders Celsius introduced the Celsius temperature scale. It was a scale based on the freezing point of water as 0 degrees and the boiling point of water as 100 degrees. The Celsius scale was often referred to as centigrade. It is very simple to convert temperatures from Celsius (centigrade) to Fahrenheit.

Things You'll Need

• Scratch paper and pen
• Calculator, if neccessary

Instructions

1. "Centi" is the prefix used in the metric system meaning one-hundredth. Each degree is one-hundredth of the way between the freezing point and the boiling point. Though Celsius is used in most countries, it is not the primary temperature scale in the United States. The U.S. uses the Fahrenheit scale. With simple mathematics, you can convert Celsius temperature to Fahrenheit.

2. Begin with the temperature in Celsius.

3. Multiply the Celsius number by 9.

4. Divide than answer by 5.

5. Add 32 to your result. The answer will be the temperature in Fahrenheit.

6. Use the following as an example of converting Celsius to Fahrenheit. If it is 37 degrees Celsius, multiply 37 by 9 and you will get 333. Divide 333 by 5, resulting in 66.6. Add 32 to 66.6 and you get 98.6. Therefore, 37 degrees Celsius is equal to 98.6 degrees Fahrenheit.

Tips & Warnings

• Teach your children how to do basic unit conversions, so that they do not have to rely on online conversion calculators.
