Unit conversion tool

Working with compressed air or nitrogen systems means constantly switching between units. A datasheet states capacity in SCFM, your process requirement is in Nm³/hr, and the pressure gauge reads in psi. This free conversion tool lets you switch between the most common units in the compressed air and gas industry, quickly and accurately.

Use the tabs below to convert pressure (bar, psi, Pascal), temperature (°C, °F, Kelvin) and capacity: Nm³/hr to SCFM, Sm³/hr to Nm³/hr, and normal flow (Nm³/hr) to actual flow (m³/hr) at your operating pressure and temperature.

All values use a decimal point and comma-separated thousands (1,000,000.00), the standard notation in our industry. Need help sizing a compressor or nitrogen generator? Our engineers are happy to calculate it with you.
