Air Density

Calculate humid-air mass density and compare it with standard sea-level air.

Starting values are examples. Enter your measurements; results update as you type.

Method & assumptions

Use absolute station pressure from a weather station. A weather app’s sea-level pressure is not station pressure. Results describe the air at the entered conditions; they do not predict an engine tune. Standard density is 1.225 kg/m³.
