About Converting Gallons per Millisecond to Cup per Hours
Gallon per Millisecond and Cup per Hours 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
cup per hours = gallons per millisecond × 57600000
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 cup per hours equals 6.571895e-8 base units, so dividing one by the other gives the direct gallon per millisecond-to-cup per hours factor of 57600000.
Simple example
1 gal/ms × 57600000 = 57,600,000 cup/h
1 gallon per millisecond = 57,600,000 cup per hours.
Real-world example
60 gal/ms × 57600000 = 3,456,000,000 cup/h
60 gallons per millisecond = 3,456,000,000 cup per hours.

Frequently asked questions
How many cup per hours are in 1 gallon per millisecond?
1 gallon per millisecond equals 57,600,000 cup per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to cup per hours?
Multiply the gallon per millisecond value by 57600000. The converter above does this instantly to whatever precision you set.
How do I convert cup per hours back to gallon per millisecond?
Use the reverse factor: 1 cup per hours equals 1.736111e-8 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
What is a cup per hours?
Cup per Hours (cup/h) is a unit of flow rate.
Is the gallon per millisecond to cup per hours conversion exact?
Yes. Both gallon per millisecond and cup per hours are defined by fixed standards rather than physical artifacts, so the factor of 57600000 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.
