## 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:

- First, determine the total strength (N/m^2).
- The total strength (N/m^2) is given as: 40,000.

- Next, determine the total weight (kg).
- The total weight (kg) is provided as: 300.

- 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.
