Formula

Formula
m³/min = gal/day (US) × 2.628758e-6

Multiply any value in US gallons per day by 2.628758e-6 to obtain the value in cubic metres per minute.

Worked example

Convert 1.00000e+6 gal/day (US) to m³/min.

  1. 01Start with 1.00000e+6 gal/day (US).
  2. 02Multiply by the conversion factor: 1.00000e+6 × 2.628758e-6 = 2.62876 m³/min.
Result1.00000e+6 gal/day (US) = 2.62876 m³/min

FAQ

What is the conversion factor from gal/day (US) to m³/min?
1 gal/day (US) equals 2.628758e-6 m³/min. To convert, multiply the value in US gallons per day by 2.628758e-6.
How do I convert 1 gal/day (US) to m³/min?
1 gal/day (US) = 2.62876e-6 m³/min. For any value, multiply by 2.628758e-6.
How do I convert m³/min back to gal/day (US)?
Divide by the same factor — or equivalently, multiply by 380407.8. So 1 m³/min = 380408 gal/day (US).
When would I need to convert US gallon per day to cubic metre 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. gal/day (US) to m³/min 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).
