Air - Density and Specific Volume vs. Altitude

Calculate and visualize air density and specific volume as functions of altitude above sea level. The tool provides pressure-altitude relationships, density corrections, and volume correction factors based on standard atmospheric conditions.

Calculator

Inputs

Altitude (m)

Temperature (°C)

Reference Density (at sea level, 20°C) (kg/m³)

Results

Atmospheric Pressure-- kPa

Air Density-- kg/m³

Specific Volume-- m³/kg
