Atmospheric Pressure Calculator

Enter the sea level pressure, altitude, and temperature into the calculator to determine the atmospheric temperature at altitude.

Atmospheric Pressure Formula

The following formula is used to calculate an atmospheric pressure at a certain altitude.

  • Where P is the atmospheric pressure
  • P0 is the base level pressure at no height (101325 Pa)
  • H is the height (meters)
  • T is the temperature (K)
  • g is the acceleration due to gravity (9.8 m/s^2)
  • M is the molar mass of dray air (.028969 kg/mol)
  • R is the universal gas constant (8.3144626 mol*K)

Atmospheric Pressure Definition

An atmospheric pressure is a measure of the pressure acting on an object in the atmosphere at some altitude.

Atmospheric Pressure Example

How to calculate atmospheric pressure?

  1. First, determine the height.

    Measure or calculate the altitude in the atmosphere.

  2. Next, determine the temperature.

    Measure the temperature of the surrounding air.

  3. Finally, calculate the atmospheric pressure.

    Calculate the atmospheric pressure using the equation above.


What is atmospheric pressure?

Atmospheric pressure is the air pressure that acts on an object due to the weight of gas particles under the effect of Earth’s gravity.
