About Converting Cubic Meters per Millisecond to Imperial gallon per Hours
Cubic Meter per Millisecond and Imperial gallon per Hours 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 gallon per hours = cubic meters per millisecond × 791889293.877
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per millisecond equals 1000 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct cubic meter per millisecond-to-imperial gallon per hours factor of 791889293.877.
Simple example
1 m3/ms × 791889293.9 = 791,889,293.9 imp gal/h
1 cubic meter per millisecond = 791,889,293.9 imperial gallon per hours.
Real-world example
60 m3/ms × 791889293.9 = 47,513,357,630 imp gal/h
60 cubic meters per millisecond = 47,513,357,630 imperial gallon per hours.

Frequently asked questions
How many imperial gallon per hours are in 1 cubic meter per millisecond?
1 cubic meter per millisecond equals 791,889,293.9 imperial gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per millisecond to imperial gallon per hours?
Multiply the cubic meter per millisecond value by 791889293.9. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per hours back to cubic meter per millisecond?
Use the reverse factor: 1 imperial gallon per hours equals 1.262803e-9 cubic meters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per millisecond?
Cubic Meter per Millisecond (m3/ms) is a unit of flow rate.
What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
Is the cubic meter per millisecond to imperial gallon per hours conversion exact?
Yes. Both cubic meter per millisecond and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 791889293.9 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.
