About Converting Imperial quart per Hours to Cubic Millimeter per Seconds
Imperial quart per Hours and Cubic Millimeter per Seconds 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 millimeter per seconds = imperial quart per hours × 315.700694444
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 seconds equals 1e-9 base units, so dividing one by the other gives the direct imperial quart per hours-to-cubic millimeter per seconds factor of 315.700694444.
Simple example
1 imp qt/h × 315.7006944 = 315.7006944 mm3/s
1 imperial quart per hours = 315.7006944 cubic millimeter per seconds.
Real-world example
60 imp qt/h × 315.7006944 = 18,942.04167 mm3/s
60 imperial quart per hours = 18,942.04167 cubic millimeter per seconds.

Frequently asked questions
How many cubic millimeter per seconds are in 1 imperial quart per hours?
1 imperial quart per hours equals 315.7006944 cubic millimeter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per hours to cubic millimeter per seconds?
Multiply the imperial quart per hours value by 315.7006944. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per seconds back to imperial quart per hours?
Use the reverse factor: 1 cubic millimeter per seconds equals 0.0031675572 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 seconds?
Cubic Millimeter per Seconds (mm3/s) is a unit of flow rate.
Is the imperial quart per hours to cubic millimeter per seconds conversion exact?
Yes. Both imperial quart per hours and cubic millimeter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 315.7006944 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.
