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)

To calculate a strength to weight ratio, divide the total strength by the total weight.

## 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
