## Weight to Length Formula

The following formula is used to calculate the Weight to Length.

**L = W/9.81/D/A**

- Where L is the Weight to Length (m)
- W is the total weight (N)
- D is the density (kg/m^3)
- A is the cross-sectional area (m^2)

## How to Calculate Weight to Length?

The following two example problems outline the steps and information needed to calculate the Weight to Length.

**Example Problem #1**

- First, determine the total weight (N).
- The total weight (N) is calculated to be : 500.

- Next, determine the density (kg/m^3).
- The density (kg/m^3) is measured to be: 3.

- Next, determine the cross-sectional area (m^2).
- The cross-sectional area (m^2) is found to be: 5.

- Finally, calculate the Weight to Length using the formula above:

L = W/9.81/D/A

The values provided above are inserted into the equation below and computed.

L = 500/9.81/3/5 = 3.397 (m)

**Example Problem #2**

The variables required for this problem are provided below:

total weight (N) = 600

density (kg/m^3) = 4

cross-sectional area (m^2) = 8

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

L = W/9.81/D/A =** **(m)
