Unit definition
Litres per minute (L/min) One litres per minute equals 0.0000166666666667 cubic metre per second.
Unit history
Litres per minute is represented here using its modern SI definition or an internationally accepted relationship to an SI base unit.
Step by step
1. Parse the value, including fractions.
2. Convert L/min to cubic metre per second.
3. Convert the base value to gpm and apply your display precision.
Understand the result before using it
Litres per minute to US gallons per minute converts a value measured in Litres per minute (L/min) into the equivalent value in US gallons per minute (gpm). The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
result = input × 0.000016666666666666667 ÷ 0.0000630901964
Assumptions
- Litres per minute and US gallons per minute represent the same flow rate quantity.
- The input is expressed in L/min; the output is expressed in gpm.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 L/min = 0.264172052358 gpm. For another value, apply the same relationship and round only to the precision your source measurement supports.
When to use it
Good uses
- Read a L/min measurement in a document that expects gpm.
- Compare a litres per minute value with a value reported in us gallons per minute.
- Check the L/min-to-gpm arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- Do not confuse L/min with another unit that has a similar name or symbol.
- Round the output to a precision justified by the original measurement.
- Verify safety-critical, regulated, laboratory, and contractual conversions against the controlling standard.
