How It Works

Flow Rate Converter

Conversion Factors from Liters per Minute

  • US Gallons per Minute: L/min × 0.264172
  • Cubic Meters per Hour: L/min × 0.06
  • Cubic Feet per Minute: L/min × 0.0353147
  • Liters per Hour: L/min × 60

    • Worked Example

    Convert 10 L/min to other flow rate units.

    value = 10
    1. 01GPM = 10 × 0.264172 = 2.6417 GPM
    2. 02m³/hr = 10 × 0.06 = 0.6 m³/hr
    3. 03CFM = 10 × 0.0353147 = 0.3531 CFM
    4. 04L/hr = 10 × 60 = 600 L/hr
