About Converting Imperial gallon per Hours to Cubic Meter per Years
Imperial gallon per Hours and Cubic Meter per Years 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
cubic meter per years = imperial gallon per hours × 39.8502066438
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per hours equals 0.00000126280277778 base units, and 1 cubic meter per years equals 3.168874e-8 base units, so dividing one by the other gives the direct imperial gallon per hours-to-cubic meter per years factor of 39.8502066438.
Simple example
1 imp gal/h × 39.85020664 = 39.85020664 m3/yr
1 imperial gallon per hours = 39.85020664 cubic meter per years.
Real-world example
60 imp gal/h × 39.85020664 = 2,391.012399 m3/yr
60 imperial gallon per hours = 2,391.012399 cubic meter per years.

Frequently asked questions
How many cubic meter per years are in 1 imperial gallon per hours?
1 imperial gallon per hours equals 39.85020664 cubic meter per years, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per hours to cubic meter per years?
Multiply the imperial gallon per hours value by 39.85020664. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per years back to imperial gallon per hours?
Use the reverse factor: 1 cubic meter per years equals 0.0250939728 imperial gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
What is a cubic meter per years?
Cubic Meter per Years (m3/yr) is a unit of flow rate.
Is the imperial gallon per hours to cubic meter per years conversion exact?
Yes. Both imperial gallon per hours and cubic meter per years are defined by fixed standards rather than physical artifacts, so the factor of 39.85020664 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.
