Formula

Formula
gph (US) = m³/s × 951019.4

Multiply any value in cubic metres per second by 951019.4 to obtain the value in US gallons per hour.

Worked example

Convert 1 m³/s to gph (US).

  1. 01Start with 1 m³/s.
  2. 02Multiply by the conversion factor: 1 × 951019.4 = 951019 gph (US).
Result1 m³/s = 951019 gph (US)

FAQ

What is the conversion factor from m³/s to gph (US)?
1 m³/s equals 951019.4 gph (US). To convert, multiply the value in cubic metres per second by 951019.4.
How do I convert 1 m³/s to gph (US)?
1 m³/s = 951019 gph (US). For any value, multiply by 951019.4.
How do I convert gph (US) back to m³/s?
Divide by the same factor — or equivalently, multiply by 1.051503e-6. So 1 gph (US) = 1.0515e-6 m³/s.
When would I need to convert cubic metre per second to US gallon per hour?
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 gph (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).
