About this calculator

This calculator converts compressed air or ventilation flow rate from cubic feet per minute (CFM), the common imperial unit, to cubic metres per minute (m³/min), the standard metric unit used on Indian and European compressor datasheets.

Formula

m³/min = CFM × 0.0283168
  • CFMFlow rate — cubic feet per minute
  • m³/minFlow rate — cubic metres per minute

Worked Example

Given: A compressor's free air delivery is rated at 100 CFM.

Result: 100 × 0.0283168 = 2.83 m³/min.

How to Use

  1. Enter the flow rate in CFM.
  2. Click Calculate to get the equivalent value in m³/min.

Important Assumptions

  • This is a pure volumetric unit conversion; it does not adjust for the reference conditions (temperature/pressure) that CFM or FAD figures may be quoted at — check that both values use the same reference condition.

Common Mistakes

  • Comparing a compressor's CFM (often at ANR/standard conditions) directly to another maker's m³/min figure without checking both use the same reference temperature and pressure.

Frequently Asked Questions

Is CFM the same everywhere, or does it depend on conditions?

CFM can be quoted at actual, standard (SCFM) or ANR reference conditions; always check which basis a compressor's rating uses before comparing between brands.
