About Converting Imperial gallon per Hours to Megaliter per Years
Imperial gallon per Hours and Megaliter 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
megaliter per years = imperial gallon per hours × 0.0398502066438
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 megaliter per years equals 0.0000316887385068 base units, so dividing one by the other gives the direct imperial gallon per hours-to-megaliter per years factor of 0.0398502066438.
Simple example
1 imp gal/h × 0.03985020664 = 0.0398502066 ML/yr
1 imperial gallon per hours = 0.0398502066 megaliter per years.
Real-world example
60 imp gal/h × 0.03985020664 = 2.391012399 ML/yr
60 imperial gallon per hours = 2.391012399 megaliter per years.

Multiply the imperial gallon per hours value by 0.03985020664. The converter above does this instantly to whatever precision you set.
How do I convert megaliter per years back to imperial gallon per hours?
Use the reverse factor: 1 megaliter per years equals 25.09397276 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 megaliter per years?
Megaliter per Years (ML/yr) is a unit of flow rate.
Is the imperial gallon per hours to megaliter per years conversion exact?
Yes. Both imperial gallon per hours and megaliter per years are defined by fixed standards rather than physical artifacts, so the factor of 0.03985020664 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.
