About Converting Imperial gallon per Hours to Milliliter per Seconds
Imperial gallon per Hours and Milliliter per Seconds 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
milliliter per seconds = imperial gallon per hours × 1.26280277778
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 milliliter per seconds equals 0.000001 base units, so dividing one by the other gives the direct imperial gallon per hours-to-milliliter per seconds factor of 1.26280277778.
Simple example
1 imp gal/h × 1.262802778 = 1.262802778 mL/s
1 imperial gallon per hours = 1.262802778 milliliter per seconds.
Real-world example
60 imp gal/h × 1.262802778 = 75.76816667 mL/s
60 imperial gallon per hours = 75.76816667 milliliter per seconds.

Frequently asked questions
How many milliliter per seconds are in 1 imperial gallon per hours?
1 imperial gallon per hours equals 1.262802778 milliliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per hours to milliliter per seconds?
Multiply the imperial gallon per hours value by 1.262802778. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per seconds back to imperial gallon per hours?
Use the reverse factor: 1 milliliter per seconds equals 0.7918892939 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 milliliter per seconds?
Milliliter per Seconds (mL/s) is a unit of flow rate.
Is the imperial gallon per hours to milliliter per seconds conversion exact?
Yes. Both imperial gallon per hours and milliliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1.262802778 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.
