About Converting Imperial quart per Hours to Cubic Millimeters per Millisecond
Imperial quart per Hours and Cubic Millimeter 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
cubic millimeters per millisecond = imperial quart per hours × 0.315700694444
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per hours equals 3.157007e-7 base units, and 1 cubic millimeter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct imperial quart per hours-to-cubic millimeter per millisecond factor of 0.315700694444.
Simple example
1 imp qt/h × 0.3157006944 = 0.3157006944 mm3/ms
1 imperial quart per hours = 0.3157006944 cubic millimeters per millisecond.
Real-world example
60 imp qt/h × 0.3157006944 = 18.94204167 mm3/ms
60 imperial quart per hours = 18.94204167 cubic millimeters per millisecond.

Frequently asked questions
How many cubic millimeters per millisecond are in 1 imperial quart per hours?
1 imperial quart per hours equals 0.3157006944 cubic millimeters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per hours to cubic millimeter per millisecond?
Multiply the imperial quart per hours value by 0.3157006944. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per millisecond back to imperial quart per hours?
Use the reverse factor: 1 cubic millimeter per millisecond equals 3.167557176 imperial quart per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per hours?
Imperial quart per Hours (imp qt/h) is a unit of flow rate.
What is a cubic millimeter per millisecond?
Cubic Millimeter per Millisecond (mm3/ms) is a unit of flow rate.
Is the imperial quart per hours to cubic millimeter per millisecond conversion exact?
Yes. Both imperial quart per hours and cubic millimeter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.3157006944 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.
