About Converting Imperial quart per Hours to Milliliters per Millisecond
Imperial quart per Hours and Milliliter 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
milliliters per millisecond = imperial quart per hours × 0.000315700694444
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 milliliter per millisecond equals 0.001 base units, so dividing one by the other gives the direct imperial quart per hours-to-milliliter per millisecond factor of 0.000315700694444.
Simple example
1 imp qt/h × 0.0003157006944 = 0.0003157007 mL/ms
1 imperial quart per hours = 0.0003157007 milliliters per millisecond.
Real-world example
60 imp qt/h × 0.0003157006944 = 0.0189420417 mL/ms
60 imperial quart per hours = 0.0189420417 milliliters per millisecond.

Frequently asked questions
How many milliliters per millisecond are in 1 imperial quart per hours?
1 imperial quart per hours equals 0.0003157007 milliliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per hours to milliliter per millisecond?
Multiply the imperial quart per hours value by 0.0003157006944. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per millisecond back to imperial quart per hours?
Use the reverse factor: 1 milliliter per millisecond equals 3,167.557176 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 milliliter per millisecond?
Milliliter per Millisecond (mL/ms) is a unit of flow rate.
Is the imperial quart per hours to milliliter per millisecond conversion exact?
Yes. Both imperial quart per hours and milliliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0003157006944 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.
