About Converting Cup per Hours to Quart per Hours
Cup per Hours and Quart 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
quart per hours = cup per hours × 0.25
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per hours equals 6.571895e-8 base units, and 1 quart per hours equals 2.628758e-7 base units, so dividing one by the other gives the direct cup per hours-to-quart per hours factor of 0.25.
Simple example
1 cup/h × 0.25 = 0.25 qt/h
1 cup per hours = 0.25 quart per hours.
Real-world example
60 cup/h × 0.25 = 15 qt/h
60 cup per hours = 15 quart per hours.

Frequently asked questions
How many quart per hours are in 1 cup per hours?
1 cup per hours equals 0.25 quart per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cup per hours to quart per hours?
Multiply the cup per hours value by 0.25. The converter above does this instantly to whatever precision you set.
How do I convert quart per hours back to cup per hours?
Use the reverse factor: 1 quart per hours equals 4 cup per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per hours?
Cup per Hours (cup/h) is a unit of flow rate.
What is a quart per hours?
Quart per Hours (qt/h) is a unit of flow rate.
Is the cup per hours to quart per hours conversion exact?
Yes. Both cup per hours and quart per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.25 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.
