# What is atmospheric pressure in pounds per square foot?

## What is atmospheric pressure in pounds per square foot?

The standard atmosphere (symbol: atm) is a unit of pressure equal to 101325 Pa (‘pascals’) or 1013.25 millibars or hectopascals. It is equivalent to 760 mmHg (torr), 14.696 psi. This tool converts atmospheres to pounds per square foot (atm to psf) and vice versa. 1 atmosphere = 2116.2166236739 pounds per square foot.

## How many pounds per square inch is the atmosphere?

We know that air weighs 14.7 psi or pounds per square inch at sea level – meaning about 15 pounds are pressing down on every square inch of you. In other words, that’s about the weight of car pressing down on you all the time!

How do you convert atm to psf?

To convert an atmosphere measurement to a pound per square foot measurement, multiply the pressure by the conversion ratio. The pressure in pounds per square foot is equal to the atmospheres multiplied by 2,116.218862.

How do you calculate pounds per square foot?

Divide force by area to calculate the pressure exerted. Continuing with the example, divide the elephant’s 5,940 lbs by 3.14 square feet to calculate the pressure of 1,891 pounds per square foot. Divide the little girl’s 55 lbs by 0.0009 to calculate her pressure of 61,111 pounds per square foot.

### How much is a pound force?
