About Converting Gallon per Hours to Milliliters per Millisecond
Gallon per Hours and Milliliter 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
milliliters per millisecond = gallon per hours × 0.00105150327333
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per hours equals 0.00000105150327333 base units, and 1 milliliter per millisecond equals 0.001 base units, so dividing one by the other gives the direct gallon per hours-to-milliliter per millisecond factor of 0.00105150327333.
Simple example
1 gal/h × 0.001051503273 = 0.0010515033 mL/ms
1 gallon per hours = 0.0010515033 milliliters per millisecond.
Real-world example
60 gal/h × 0.001051503273 = 0.0630901964 mL/ms
60 gallon per hours = 0.0630901964 milliliters per millisecond.

Frequently asked questions
How many milliliters per millisecond are in 1 gallon per hours?
1 gallon per hours equals 0.0010515033 milliliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to milliliter per millisecond?
Multiply the gallon per hours value by 0.001051503273. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per millisecond back to gallon per hours?
Use the reverse factor: 1 milliliter per millisecond equals 951.0193885 gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
What is a milliliter per millisecond?
Milliliter per Millisecond (mL/ms) is a unit of flow rate.
Is the gallon per hours to milliliter per millisecond conversion exact?
Yes. Both gallon per hours and milliliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.001051503273 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.
