About Converting Liter per Hours to Imperial gallons per Millisecond
Liter per Hours 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 = liter per hours × 6.110257e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per hours equals 2.777778e-7 base units, and 1 imperial gallon per millisecond equals 4.54609 base units, so dividing one by the other gives the direct liter per hours-to-imperial gallon per millisecond factor of 6.110257e-8.
Simple example
1 L/h × 6.110257e-8 = 6.110257e-8 imp gal/ms
1 liter per hours = 6.110257e-8 imperial gallons per millisecond.
Real-world example
60 L/h × 6.110257e-8 = 0.0000036662 imp gal/ms
60 liter per hours = 0.0000036662 imperial gallons per millisecond.

Frequently asked questions
How many imperial gallons per millisecond are in 1 liter per hours?
1 liter per hours equals 6.110257e-8 imperial gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert liter per hours to imperial gallon per millisecond?
Multiply the liter per hours value by 6.110257e-8. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per millisecond back to liter per hours?
Use the reverse factor: 1 imperial gallon per millisecond equals 16,365,924 liter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per hours?
Liter per Hours (L/h) 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 hours to imperial gallon per millisecond conversion exact?
Yes. Both liter per hours and imperial gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 6.110257e-8 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.
