GPM to CFS Calculator
Cubic Feet per Second (CFS): 0.00
What is GPM?
Gallons per minute (GPM) measures the flow rate of liquids, commonly used in:
- Plumbing systems
- Irrigation
- Industrial processes
- Firefighting hydrants
What is CFS?
Cubic feet per second (CFS) measures the volume of water passing a point each second, often used in:
- Hydrology & river flow measurements
- Stormwater management
- Large-scale water distribution
How to Convert GPM to CFS
The conversion formula is simple:
CFS=GPM÷ 448.831
Why 448.831?
- 1 cubic foot = 7.48052 gallons
- 1 minute = 60 seconds
- So, 1 CFS = 7.48052 × 60 ≈ 448.831 GPM
