Formula

Formula
gal/day (US) = m³/day × 264.1721

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

Worked example

Convert 1 m³/day to gal/day (US).

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

FAQ

What is the conversion factor from m³/day to gal/day (US)?
1 m³/day equals 264.1721 gal/day (US). To convert, multiply the value in cubic metres per day by 264.1721.
How do I convert 1 m³/day to gal/day (US)?
1 m³/day = 264.172 gal/day (US). For any value, multiply by 264.1721.
How do I convert gal/day (US) back to m³/day?
Divide by the same factor — or equivalently, multiply by 0.003785412. So 1 gal/day (US) = 0.00378541 m³/day.
When would I need to convert cubic metre per day to US gallon per day?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. m³/day to gal/day (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).
