Enter the weight at sea level (pounds) and the total altitude (ft) into the Altitude Weight Calculator. The calculator will evaluate the Altitude Weight.

## Altitude Weight Formula

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

ALTW = WSL - A /10,000 * .08

Variables:

- ALTW is the Altitude Weight (pounds)
- WSL is the weight at sea level (pounds)
- A is the total altitude (ft)

To calculate weight at altitude, divide the total altitude by 10,000, multiply by .08, then subtract this result from the weight at sea level.

## How to Calculate Altitude Weight?

The following steps outline how to calculate the Altitude Weight.

- First, determine the weight at sea level (pounds).
- Next, determine the total altitude (ft).
- Next, gather the formula from above = ALTW = WSL – A /10,000 * .08.
- Finally, calculate the Altitude Weight.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

weight at sea level (pounds) = 200

total altitude (ft) = 30,000

ALTW = WSL – A /10,000 * .08** **= ?
