Quickly Convert Gas and Flow Rate Units Like SFM, Nm3/hr, and More

Many different measurement units are commonly used to define gas and liquid flow rates.  This online unit converter allows users to enter available flow rate or usage rate information and, with one  click, calculate a set of equivalent measures – per hour, per day, per month or year – for common industrial gases in both “English” and “Metric” units.  —- Check the notes at the bottom regarding assumptions used in this table.

Volume Measures - ALL GASES

O2 - OXYGEN ONLY

N2 - NITROGEN ONLY

Ar - ARGON ONLY

CO2 ONLY

  • Based on: 1 year = 365.25 days 1 year = 12 months (1 average month = 30.44 days = 730.5 hours)
  • Scf (standard cubic foot) gas measured at 1 atmosphere and 70°F.
  • Nm³ (normal cubic meter) gas measured at 1 atmosphere and 0°C.
  • Liquid measured at 1 atmosphere and boiling temperature.
  • Results may need to be adjusted if usage is not continuous throughout the month. Call UIG for help if needed.
