About Converting Cubic Meter per Hours to Imperial gallon per Minutes
Cubic Meter per Hours and Imperial 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. Cubic Meter per Hours is most often used for hvac equipment airflow and liquid-flow ratings.
Formula
imperial gallon per minutes = cubic meter per hours × 3.66615413832
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per hours equals 0.000277777777778 base units, and 1 imperial gallon per minutes equals 0.0000757681666667 base units, so dividing one by the other gives the direct cubic meter per hours-to-imperial gallon per minutes factor of 3.66615413832.
Simple example
1 m3/h × 3.666154138 = 3.666154138 imp gal/min
1 cubic meter per hours = 3.666154138 imperial gallon per minutes.
Real-world example
60 m3/h × 3.666154138 = 219.9692483 imp gal/min
60 cubic meter per hours = 219.9692483 imperial gallon per minutes.

What is a cubic meter per hours?
Cubic Meter per Hours (m3/h) measures volumetric flow rate. One cubic meter of volume passing a point every hour — a common scale for equipment and system flow ratings. It is classified as a metric derived flow-rate unit.
What is a imperial gallon per minutes?
Imperial gallon per Minutes (imp gal/min) is a unit of flow rate.
Is the cubic meter per hours to imperial gallon per minutes conversion exact?
Yes. Both cubic meter per hours and imperial gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 3.666154138 used above is exact to as many digits as you choose to display.

Standard flow-rate unit for HVAC and industrial equipment ratings internationally, outside the US
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.
