Enter the total torque (N-m) and the angular velocity (rad/s) into the calculator to determine the Power From Torque. 

Power From Torque Formula

The following formula is used to calculate the Power From Torque. 

P = t*w
  • Where P is the Power From Torque (watts)
  • t is the total torque (N-m) 
  • w is the angular velocity (rad/s) 

To calculate power from torque, multiply the torque by the angular velocity.

How to Calculate Power From Torque?

The following two example problems outline how to calculate the Power From Torque.

Example Problem #1:

  1. First, determine the total torque (N-m). In this example, the total torque (N-m) is measured to be 93.
  2. Next, determine the angular velocity (rad/s). For this problem, the angular velocity (rad/s) is calculated to be 75.
  3. Finally, calculate the Power From Torque using the formula above: 

P = t*w

Inserting the values from above and solving the equation with the imputed values gives: 

P = 93*75 = 6975 (watts)

Example Problem #2: 

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

total torque (N-m) = 61

angular velocity (rad/s) = 41

Entering these values into the formula or calculator above gives us:: 

P = 61*41 = 2501 (watts)
