VOLUME CONVERSIONStandard

Quickly convert actual intake air flow (FAD) to standard reference (Nm³ DIN 1343 & Sm³ ISO 2533).

View calculation basis

Nm³ (DIN 1343)

0 °C, 1.013 bar, 0% RH

Sm³ (ISO 2533)

INPUT PARAMETERS

Intake conditions

1. Actual flow

Air volume

m³

2. Air environment

Temperature (T)

°C

Relative humidity (RH)

3. Pressure conditions

Altitude above sea level

Atmospheric pressure (P_act)

Configuration note:

This is a conversion calculation tool based on the Thermodynamics theory of air compressors. The volume results Nm³ and Sm³ always refer to a 0% humidity factor (Completely dry air). The mass (kg) between DIN and ISO is approximately equal due to mass conservation.

* Actual results may vary depending on operating conditions, load levels, air leakage, and system pressure.
