Formula

Formula
L/min = gal/day (US) × 0.002628758

Multiply any value in US gallons per day by 0.002628758 to obtain the value in litres per minute.

Worked example

Convert 1000 gal/day (US) to L/min.

  1. 01Start with 1000 gal/day (US).
  2. 02Multiply by the conversion factor: 1000 × 0.002628758 = 2.62876 L/min.
Result1000 gal/day (US) = 2.62876 L/min

FAQ

What is the conversion factor from gal/day (US) to L/min?
1 gal/day (US) equals 0.002628758 L/min. To convert, multiply the value in US gallons per day by 0.002628758.
How do I convert 1 gal/day (US) to L/min?
1 gal/day (US) = 0.00262876 L/min. For any value, multiply by 0.002628758.
How do I convert L/min back to gal/day (US)?
Divide by the same factor — or equivalently, multiply by 380.4078. So 1 L/min = 380.408 gal/day (US).
When would I need to convert US gallon per day to litre 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 L/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).
