About Converting Imperial quart per Hours to Milliliter per Seconds
Imperial quart per Hours and Milliliter 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
milliliter per seconds = 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 milliliter per seconds equals 0.000001 base units, so dividing one by the other gives the direct imperial quart per hours-to-milliliter per seconds factor of 0.315700694444.
Simple example
1 imp qt/h × 0.3157006944 = 0.3157006944 mL/s
1 imperial quart per hours = 0.3157006944 milliliter per seconds.
Real-world example
60 imp qt/h × 0.3157006944 = 18.94204167 mL/s
60 imperial quart per hours = 18.94204167 milliliter per seconds.

Frequently asked questions
How many milliliter per seconds are in 1 imperial quart per hours?
1 imperial quart per hours equals 0.3157006944 milliliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per hours to milliliter per seconds?
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 milliliter per seconds back to imperial quart per hours?
Use the reverse factor: 1 milliliter per seconds 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 milliliter per seconds?
Milliliter per Seconds (mL/s) is a unit of flow rate.
Is the imperial quart per hours to milliliter per seconds conversion exact?
Yes. Both imperial quart per hours and milliliter per seconds 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.
