Formula

Formula
gpm (US) = L/min × 0.2641721

Multiply any value in litres per minute by 0.2641721 to obtain the value in US gallons per minute.

Worked example

Convert 200 L/min to gpm (US).

  1. 01Start with 200 L/min.
  2. 02Multiply by the conversion factor: 200 × 0.2641721 = 52.8344 gpm (US).
Result200 L/min = 52.8344 gpm (US)

FAQ

What is the conversion factor from L/min to gpm (US)?
1 L/min equals 0.2641721 gpm (US). To convert, multiply the value in litres per minute by 0.2641721.
How do I convert 1 L/min to gpm (US)?
1 L/min = 0.264172 gpm (US). For any value, multiply by 0.2641721.
How do I convert gpm (US) back to L/min?
Divide by the same factor — or equivalently, multiply by 3.785412. So 1 gpm (US) = 3.78541 L/min.
When would I need to convert litre 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. L/min to gpm (US) is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
Yes. Both L/min and gpm (US) are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
