Therefore, its important to consider atmospheric conditions when calculating air. When moist air is cooled, there is a certain temperature at which water vapor begins to condense. The moisture content can be described by the absolute humidity, which indicates how many grams of water are contained in one cubic meter of air. The air density at sea level and zero humidity is 1.225 kg/m³, but depending on altitude, it could go even down to 0.122 kg/m³. How much moisture is contained can be very different. With the DKS humidity calculator, the parameters volume fractions trace moisture ppmV, relative humidity RH in and the dew point temperature Tdp in ☌ in the range -70 to +100 ☌ can be approximately converted. Temperature Conversion Enter a number then click on the appropriate number to see the result. Welcome to our online air density calculator, a tool that will help you calculate the density of air in kg/m 3 and many other units.
