About Converting Imperial gallon per Hours to Megaliters per Millisecond
Imperial gallon per Hours and Megaliter per Millisecond 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
megaliters per millisecond = imperial gallon per hours × 1.262803e-12
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 millisecond equals 1000000 base units, so dividing one by the other gives the direct imperial gallon per hours-to-megaliter per millisecond factor of 1.262803e-12.
Simple example
1 imp gal/h × 1.262803e-12 = 1.262803e-12 ML/ms
1 imperial gallon per hours = 1.262803e-12 megaliters per millisecond.
Real-world example
60 imp gal/h × 1.262803e-12 = 7.576817e-11 ML/ms
60 imperial gallon per hours = 7.576817e-11 megaliters per millisecond.

Frequently asked questions
How many megaliters per millisecond are in 1 imperial gallon per hours?
1 imperial gallon per hours equals 1.262803e-12 megaliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per hours to megaliter per millisecond?
Multiply the imperial gallon per hours value by 1.262803e-12. The converter above does this instantly to whatever precision you set.
How do I convert megaliter per millisecond back to imperial gallon per hours?
Use the reverse factor: 1 megaliter per millisecond equals 791,889,293,900 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 millisecond?
Megaliter per Millisecond (ML/ms) is a unit of flow rate.
Is the imperial gallon per hours to megaliter per millisecond conversion exact?
Yes. Both imperial gallon per hours and megaliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.262803e-12 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.
