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

    Frequently Asked Questions

    How do you convert liters per minute to gallons per minute?

    Multiply the flow rate in liters per minute by 0.264172 to get US gallons per minute.

    What is CFM?

    CFM stands for cubic feet per minute. It is a common unit for measuring air flow rate in HVAC systems.
