Volumetric Flow Rate Converter

Convert volumetric flow rate between cubic meters per second, liters per minute, gallons per minute, cubic feet per minute, and dozens of other units. Essential for plumbing, HVAC, chemical engineering, and fluid mechanics calculations.

Common Flow Rate Units

Cubic meters per second (m³/s) is the SI unit. Liters per minute (L/min) and US gallons per minute (GPM) are widely used in industry and plumbing. Cubic feet per minute (CFM) is standard in HVAC applications.

Frequently Asked Questions

How do I convert GPM to L/min?

Multiply US gallons per minute by 3.785 to get liters per minute. For example, 10 GPM equals approximately 37.85 L/min. This tool handles the conversion precisely.

What is the difference between CFM and GPM?

CFM (cubic feet per minute) measures volume flow rate, while GPM (gallons per minute) also measures volume flow but in gallon units. One CFM equals approximately 7.481 GPM.

Does this tool support per-second and per-minute rates?

Yes. The converter includes both per-second and per-minute variants for most volume units, including cubic meters, liters, gallons, and cubic feet.

What is an acre-foot per second?

An acre-foot is the volume of water covering one acre to a depth of one foot. Acre-feet per second is used in large-scale water flow measurements, equal to approximately 1233.48 m³/s.
