About Converting Liters per Millisecond to Imperial gallons per Millisecond
Liter per Millisecond and Imperial gallon 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
imperial gallons per millisecond = liters per millisecond × 0.219969248299
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 imperial gallon per millisecond equals 4.54609 base units, so dividing one by the other gives the direct liter per millisecond-to-imperial gallon per millisecond factor of 0.219969248299.
Simple example
1 L/ms × 0.2199692483 = 0.2199692483 imp gal/ms
1 liter per millisecond = 0.2199692483 imperial gallons per millisecond.
Real-world example
60 L/ms × 0.2199692483 = 13.1981549 imp gal/ms
60 liters per millisecond = 13.1981549 imperial gallons per millisecond.

Frequently asked questions
How many imperial gallons per millisecond are in 1 liter per millisecond?
1 liter per millisecond equals 0.2199692483 imperial gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to imperial gallon per millisecond?
Multiply the liter per millisecond value by 0.2199692483. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per millisecond back to liter per millisecond?
Use the reverse factor: 1 imperial gallon per millisecond equals 4.54609 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 imperial gallon per millisecond?
Imperial gallon per Millisecond (imp gal/ms) is a unit of flow rate.
Is the liter per millisecond to imperial gallon per millisecond conversion exact?
Yes. Both liter per millisecond and imperial gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.2199692483 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.
