CFS to GPM Calculator
The cfs to gpm calculator is created for transforming water flow rates between cubic feet per second (CFS) and gallons per minute (GPM).
With water flow system measuring 2.5 CFS – the calculator instantly computes this equals 1,122.45 GPM.

CFS to GPM Conversion Formulas
The primary conversion formula is:
GPM = CFS × 448.8312- One cubic foot contains 7.48052 gallons
- One minute contains 60 seconds
This equation derives from:
GPM = CFS × 7.48052 gallons/cubic foot × 60 seconds/minuteHow to Convert CFS to GPM?
- Start with your flow rate in cubic feet per second
- Multiply by the conversion factor (448.8312)
- Your result gives the equivalent flow rate in gallons per minute
Converting 3 CFS: 3 CFS × 448.8312 = 1,346.49 GPM
- Stream Flow Measurement: 0.5 CFS × 448.8312 = 224.42 GPM
- Irrigation System Flow: 15 CFS × 448.8312 = 6,732.47 GPM
- Industrial Process Flow: 2.75 CFS × 448.8312 = 1,234.29 GPM
- Water Supply System: 8.3 CFS × 448.8312 = 3,725.30 GPM
- Hydroelectric System: 100 CFS × 448.8312 = 44,883.12 GPM
What is CFS and GPM?
Cubic Feet per Second (CFS) represents a volumetric flow measurement showing water movement through a specific point.
Gallons per Minute (GPM) measures fluid flow by calculating gallons passing through a point in one minute.
CFS suits large-scale water projects and municipal systems, while GPM works better for residential applications and commercial installations requiring smaller volume measurements.
