Enter the radius of revolution (m) and the speed of revolution (m/s) into the Period of Revolution Calculator. The calculator will evaluate the Period of Revolution. 

Period of Revolution Formula

The following two example problems outline the steps and information needed to calculate the Period of Revolution.

T = 2*pi*R / V


  • T is the Period of Revolution (seconds)
  • R is the radius of revolution (m) 
  • V is the speed of revolution (m/s) 

To calculate the period of revolution, multiply 2 times pi by the radius of revolution, then divide the speed of revolution.

How to Calculate Period of Revolution?

The following steps outline how to calculate the Period of Revolution.

  1. First, determine the radius of revolution (m). 
  2. Next, determine the speed of revolution (m/s). 
  3. Next, gather the formula from above = T = 2*pi*R / V.
  4. Finally, calculate the Period of Revolution.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

radius of revolution (m) = 100

speed of revolution (m/s) = 30

T = 2*pi*R / V = ?
