About Converting Metric cup per Hours to Gallons per Millisecond
Metric cup per Hours and Gallon 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
gallons per millisecond = metric cup per hours × 1.834528e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 metric cup per hours equals 6.944444e-8 base units, and 1 gallon per millisecond equals 3.785411784 base units, so dividing one by the other gives the direct metric cup per hours-to-gallon per millisecond factor of 1.834528e-8.
Simple example
1 metric cup/h × 1.834528e-8 = 1.834528e-8 gal/ms
1 metric cup per hours = 1.834528e-8 gallons per millisecond.
Real-world example
60 metric cup/h × 1.834528e-8 = 0.0000011007 gal/ms
60 metric cup per hours = 0.0000011007 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 metric cup per hours?
1 metric cup per hours equals 1.834528e-8 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert metric cup per hours to gallon per millisecond?
Multiply the metric cup per hours value by 1.834528e-8. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to metric cup per hours?
Use the reverse factor: 1 gallon per millisecond equals 54,509,929.69 metric cup per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a metric cup per hours?
Metric cup per Hours (metric cup/h) is a unit of flow rate.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the metric cup per hours to gallon per millisecond conversion exact?
Yes. Both metric cup per hours and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.834528e-8 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.
