Evaluate diameter to Circumference: The above diameter to circumference calculator will directly turn values from diameter to the equivalent circumference value. Donate Login Sign up. The diameter is always twice the radius, so either form of the equation works. Pi is a mathematical constant and is 3.1416 to four places. As nouns the difference between perimeter and circumference is that perimeter is (mathematics) the sum of the distance of all the lengths of the sides of an object while circumference is (geometry) the line that bounds a circle or other two-dimensional figure. by . Both calculations are designed to round up. This constant ratio is denoted by the Greek letter $$\pi$$. If we say the circumference is 1600 pi, and this is equal to pi times the diameter, we can just divide both sides by pi to get the diameter, which is going to be 1600. Circumference definition, the outer boundary, especially of a circular area; perimeter: the circumference of a circle. They are two different measurements of length, but they share a special mathematical relationship with the constant pi. Circumference of a circle is defined as the distance around it.
