Litres per minute to US gallons per minute

1 litre per minute = 0.26417 US gallons per minute · 1 gpm (US) = 3.7854 L/min

1 litre per minute = 0.26417 US gallons per minute

How it’s calculated

gpm (US) = L/min × 0.2641720524

  • Multiply the value in litres per minute by 0.2641720524.
  • To go back, divide by 0.2641720524 (or multiply by 3.785411784).
  • 1 L/min = 0.2641720524 gpm (US) · 1 gpm (US) = 3.785411784 L/min

  1. Find the conversion factor

    By definition 1 L/min = 0.0000166666666666667 m³/s and 1 gpm (US) = 0.0000630901964 m³/s, so 1 gpm (US) = 3.785411784 L/min. Source: BIPM SI Brochure (9th ed.) (SI prefixes and accepted units); NIST SP 811 / Handbook 44.

  2. Multiply by the factor written as a fraction

    Put L/min in the denominator so it cancels, leaving gpm (US).

  3. Calculate (unrounded)

  4. Round the answer

    Rounded to 5 significant figures.
