Formula

Formula
gpm (US) = m³/min × 264.1721

Multiply any value in cubic metres per minute by 264.1721 to obtain the value in US gallons per minute.

Worked example

Convert 1 m³/min to gpm (US).

  1. 01Start with 1 m³/min.
  2. 02Multiply by the conversion factor: 1 × 264.1721 = 264.172 gpm (US).
Result1 m³/min = 264.172 gpm (US)

FAQ

What is the conversion factor from m³/min to gpm (US)?
1 m³/min equals 264.1721 gpm (US). To convert, multiply the value in cubic metres per minute by 264.1721.
How do I convert 1 m³/min to gpm (US)?
1 m³/min = 264.172 gpm (US). For any value, multiply by 264.1721.
How do I convert gpm (US) back to m³/min?
Divide by the same factor — or equivalently, multiply by 0.003785412. So 1 gpm (US) = 0.00378541 m³/min.
When would I need to convert cubic metre per minute 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/min 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).
