About Converting Gallon per Hours to Metric cups per Millisecond
Gallon per Hours and Metric cup 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
metric cups per millisecond = gallon per hours × 0.00000420601309333
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 metric cup per millisecond equals 0.25 base units, so dividing one by the other gives the direct gallon per hours-to-metric cup per millisecond factor of 0.00000420601309333.
Simple example
1 gal/h × 0.000004206013093 = 0.000004206 metric cup/ms
1 gallon per hours = 0.000004206 metric cups per millisecond.
Real-world example
60 gal/h × 0.000004206013093 = 0.0002523608 metric cup/ms
60 gallon per hours = 0.0002523608 metric cups per millisecond.

Frequently asked questions
How many metric cups per millisecond are in 1 gallon per hours?
1 gallon per hours equals 0.000004206 metric cups per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to metric cup per millisecond?
Multiply the gallon per hours value by 0.000004206013093. The converter above does this instantly to whatever precision you set.
How do I convert metric cup per millisecond back to gallon per hours?
Use the reverse factor: 1 metric cup per millisecond equals 237,754.8471 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 metric cup per millisecond?
Metric cup per Millisecond (metric cup/ms) is a unit of flow rate.
Is the gallon per hours to metric cup per millisecond conversion exact?
Yes. Both gallon per hours and metric cup per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000004206013093 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.
