Formula

Formula
gpm (US) = m³/s × 15850.32

Multiply any value in cubic metres per second by 15850.32 to obtain the value in US gallons per minute.

Worked example

Convert 0.1 m³/s to gpm (US).

  1. 01Start with 0.1 m³/s.
  2. 02Multiply by the conversion factor: 0.1 × 15850.32 = 1585.03 gpm (US).
Result0.1 m³/s = 1585.03 gpm (US)

FAQ

What is the conversion factor from m³/s to gpm (US)?
1 m³/s equals 15850.32 gpm (US). To convert, multiply the value in cubic metres per second by 15850.32.
How do I convert 1 m³/s to gpm (US)?
1 m³/s = 15850.3 gpm (US). For any value, multiply by 15850.32.
How do I convert gpm (US) back to m³/s?
Divide by the same factor — or equivalently, multiply by 6.30902e-5. So 1 gpm (US) = 6.30902e-5 m³/s.
When would I need to convert cubic metre per second to US gallon per minute?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. m³/s to gpm (US) is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
