Enter the total strength (N/m^2) and the total weight (kg) into the Strength to Weight Ratio Calculator. The calculator will evaluate and display the Strength to Weight Ratio. 

Strength to Weight Ratio Formula

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

SWR = S / W

  • Where SWR is the Strength to Weight Ratio (N/m^2/kg)
  • S is the total strength (N/m^2) 
  • W is the total weight (kg) 

How to Calculate Strength to Weight Ratio?

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

Example Problem #1:

  1. First, determine the total strength (N/m^2). 
    • The total strength (N/m^2) is given as: 40,000.
  2. Next, determine the total weight (kg). 
    • The total weight (kg) is provided as: 300.
  3. Finally, calculate the Strength to Weight Ratio using the equation above: 

SWR = S / W

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

SWR = 40,000 / 300 = 133.33 (N/m^2/kg)


Example Problem #2: 

For this problem, the variables required are provided below:

total strength (N/m^2) = 30,000

total weight (kg) = 100

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

SWR = S / W = ?
