How to Convert Circumference to Diameter on a Calculator

Save

The circumference and diameter of a circle depend on each other for definition. A circle's circumference is the measurement of its entire border, and its diameter is a straight measurement that goes through the circle's origin between two points on the circumference. The two measurements are bound by pi, which is a-circumference-to-diameter ratio known as 3.142 in simpler calculations, in the equation circumference equals diameter * pi. You can convert a measurement of circumference to its corresponding diameter by the working the equation backward on your calculator.

  • Enter the circumference into the calculator with the digit keys. For this example, let the circumference be 600.

  • Press the key for division. On most calculators, the division key will be signified as either "÷" or "/".

  • Press the pi key, which will be represented as "pi" or "π". If you calculator does not have a key for pi, enter "3.142" with the keypad.

  • Press "Enter" or the equal sign ("=") to calculate the diameter. Concluding this example, the diameter equals approximately 190.986.
