About Converting Imperial gallon per Hours to Megaliter per Decades
Imperial gallon per Hours and Megaliter per Decades 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 decades = imperial gallon per hours × 0.398502066438
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 decades equals 0.00000316887385068 base units, so dividing one by the other gives the direct imperial gallon per hours-to-megaliter per decades factor of 0.398502066438.
Simple example
1 imp gal/h × 0.3985020664 = 0.3985020664 ML/decade
1 imperial gallon per hours = 0.3985020664 megaliter per decades.
Real-world example
60 imp gal/h × 0.3985020664 = 23.91012399 ML/decade
60 imperial gallon per hours = 23.91012399 megaliter per decades.

Frequently asked questions
How many megaliter per decades are in 1 imperial gallon per hours?
1 imperial gallon per hours equals 0.3985020664 megaliter per decades, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per hours to megaliter per decades?
Multiply the imperial gallon per hours value by 0.3985020664. The converter above does this instantly to whatever precision you set.
How do I convert megaliter per decades back to imperial gallon per hours?
Use the reverse factor: 1 megaliter per decades equals 2.509397276 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 decades?
Megaliter per Decades (ML/decade) is a unit of flow rate.
Is the imperial gallon per hours to megaliter per decades conversion exact?
Yes. Both imperial gallon per hours and megaliter per decades are defined by fixed standards rather than physical artifacts, so the factor of 0.3985020664 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.
