Enter the temperature and volume into the calculator to determine the air pressure.

Air Pressure Calculation Formula

The following formula is used to calculate the air pressure based on the ideal gas law.

Pressure = (R * (Temperature + 273.15)) / Volume

Variables:

  • Pressure is the force exerted by air ($Pa$)
  • Temperature is the air temperature in Celsius (°C)
  • Volume is the space occupied by the air in cubic meters (m³)

To calculate the air pressure, multiply the specific gas constant by the absolute temperature and divide by the volume.

What is Air Pressure Calculation?

Air pressure calculation refers to the process of determining the pressure exerted by air in a given volume at a specific temperature. This is essential in various fields, including meteorology, aviation, and HVAC systems. Understanding air pressure helps in predicting weather patterns, designing aircraft, and optimizing heating and cooling systems.
