🚰 Volumetric Flow Rate Converter
Convert volumetric flow-rate units — litres per second and minute, cubic metres per hour, US gallons per minute (GPM), cubic feet per minute (CFM) and per second.
1 m³/s = 3600 m³/h
1 cubic metres per second = 3600 cubic metres per hour
1 × 3600 = 3600
1 m³/s equals 3600 m³/h, so multiplying by 3600 converts the value. The result describes the exact same quantity — only the measuring stick changes.

All volumetric flow rate units
| Unit | Symbol | Definition |
|---|---|---|
| Cubic metre per second | m³/s | The SI unit of volumetric flow — a cubic metre passing a point each second. A large unit: rivers and industrial flows. |
| Cubic metre per hour | m³/h | A cubic metre per hour is 1/3600 m³/s. Pumps, HVAC and water systems are often rated in m³/h. |
| Litre per second | L/s | One litre per second is 0.001 m³/s. A common unit for pumps and plumbing flows. |
| Litre per minute | L/min | A litre per minute is 1/60 L/s. Taps, showers and small pumps are rated in L/min. |
| US gallon per minute | GPM | US gallons per minute — the standard US pump and plumbing rate. One GPM is about 3.785 L/min. |
| Cubic foot per minute | CFM | Cubic feet per minute — the US airflow unit for fans, HVAC and compressors. One CFM is about 1.699 m³/h or 0.472 L/s. |
| Cubic foot per second | ft³/s | Cubic feet per second ("cusec") — used for river and channel discharge. One ft³/s is about 28.32 L/s. |
