Formula

Formula
gpm (US) = gal/day (US) × 0.0006944444

Multiply any value in US gallons per day by 0.0006944444 to obtain the value in US gallons per minute.

Worked example

Convert 1440 gal/day (US) to gpm (US).

  1. 01Start with 1440 gal/day (US).
  2. 02Multiply by the conversion factor: 1440 × 0.0006944444 = 1 gpm (US).
Result1440 gal/day (US) = 1 gpm (US)

FAQ

What is the conversion factor from gal/day (US) to gpm (US)?
1 gal/day (US) equals 0.0006944444 gpm (US). To convert, multiply the value in US gallons per day by 0.0006944444.
How do I convert 1 gal/day (US) to gpm (US)?
1 gal/day (US) = 0.000694444 gpm (US). For any value, multiply by 0.0006944444.
How do I convert gpm (US) back to gal/day (US)?
Divide by the same factor — or equivalently, multiply by 1440. So 1 gpm (US) = 1440 gal/day (US).
When would I need to convert US gallon per day 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. gal/day (US) 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).
