## Torque From RPM Formula

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

T = 5252.08 * P / S

- Where T is the Torque From RPM (lb-ft)
- P is the total power (HP)
- S is the rotational speed (RPM)

To calculate the torque from RPM, multiply the the horsepower by 5252.08, then divide the rotational speed.

## How to Calculate Torque From RPM?

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

**Example Problem #1:**

- First, determine the total power (HP). In this example, the total power (HP) is measured to be 500.
- Next, determine the rotational speed (RPM). For this problem, the rotational speed (RPM) is calculated to be 1000.
- Finally, calculate the Torque From RPM using the formula above:

T = 5252.08 * P / S

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

T = 5252.08 * 500 / 1000 = 2626.04 (lb-ft)

**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 power (HP) = 600

rotational speed (RPM) = 2000

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

T = 5252.08 * 600 / 2000 = 1575.62 (lb-ft)
