Enter the total torque (lbf-ft) and the total weight (lbs) into the Torque to Weight Ratio Calculator. The calculator will evaluate and display the Torque to Weight Ratio. 

Torque to Weight Ratio Formula

The following formula is used to calculate the Torque to Weight Ratio. 

TWR = TQ / W

  • Where TWR is the Torque to Weight Ratio (lbf-ft/(lbs))
  • TQ is the total torque (lbf-ft) 
  • W is the total weight (lbs) 

How to Calculate Torque to Weight Ratio?

The following example problems outline how to calculate Torque to Weight Ratio.

Example Problem #1:

  1. First, determine the total torque (lb-ft). 
    • The total torque (lbf-ft) is given as: 500.
  2. Next, determine the total weight (lbs). 
    • The total weight (lbs) is provided as: 1000.
  3. Finally, calculate the Torque to Weight Ratio using the equation above: 

TWR = TQ / W

The values given above are inserted into the equation below and the solution is calculated:

TWR = 500 / 1000 = .50 (lbf-ft/(lbs))


Example Problem #2: 

For this problem, the variables required are provided below:

total torque (lbf-ft) = 300

total weight (lbs) = 2000

Test your knowledge using the equation and check your answer with the calculator above.

TWR = TQ / W = ?
