About Converting Liters per Millisecond to Gallon per Minutes
Liter per Millisecond and Gallon per Minutes both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
gallon per minutes = liters per millisecond × 15850.3231415
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per millisecond equals 1 base unit, and 1 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct liter per millisecond-to-gallon per minutes factor of 15850.3231415.
Simple example
1 L/ms × 15850.32314 = 15,850.32314 gal/min
1 liter per millisecond = 15,850.32314 gallon per minutes.
Real-world example
60 L/ms × 15850.32314 = 951,019.3885 gal/min
60 liters per millisecond = 951,019.3885 gallon per minutes.

Reverse conversion: Gallon per Minutes to Liter per Millisecond
1 gal/min × 0.0000630901964 = 0.0000630902 L/ms
1 gallon per minutes = 0.0000630902 liters per millisecond.
liters per millisecond = gallon per minutes × 0.0000630901964

Frequently asked questions
How many gallon per minutes are in 1 liter per millisecond?
1 liter per millisecond equals 15,850.32314 gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to gallon per minutes?
Multiply the liter per millisecond value by 15850.32314. The converter above does this instantly to whatever precision you set.
How do I convert gallon per minutes back to liter per millisecond?
Use the reverse factor: 1 gallon per minutes equals 0.0000630902 liters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
Is the liter per millisecond to gallon per minutes conversion exact?
Yes. Both liter per millisecond and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 15850.32314 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
