About Converting Gallons per Millisecond to Liters per Millisecond
Gallon per Millisecond and Liter per Millisecond 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
liters per millisecond = gallons per millisecond × 3.785411784
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 liter per millisecond equals 1 base unit, so dividing one by the other gives the direct gallon per millisecond-to-liter per millisecond factor of 3.785411784.
Simple example
1 gal/ms × 3.785411784 = 3.785411784 L/ms
1 gallon per millisecond = 3.785411784 liters per millisecond.
Real-world example
60 gal/ms × 3.785411784 = 227.124707 L/ms
60 gallons per millisecond = 227.124707 liters per millisecond.

Frequently asked questions
How many liters per millisecond are in 1 gallon per millisecond?
1 gallon per millisecond equals 3.785411784 liters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to liter per millisecond?
Multiply the gallon per millisecond value by 3.785411784. The converter above does this instantly to whatever precision you set.
How do I convert liter per millisecond back to gallon per millisecond?
Use the reverse factor: 1 liter per millisecond equals 0.2641720524 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
What is a liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
Is the gallon per millisecond to liter per millisecond conversion exact?
Yes. Both gallon per millisecond and liter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 3.785411784 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.
