About Converting Quart per Hours to Milliliters per Millisecond
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 = quart per hours × 0.000262875818333
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per hours equals 2.628758e-7 base units, and 1 milliliter per millisecond equals 0.001 base units, so dividing one by the other gives the direct quart per hours-to-milliliter per millisecond factor of 0.000262875818333.
Simple example
1 qt/h × 0.0002628758183 = 0.0002628758 mL/ms
1 quart per hours = 0.0002628758 milliliters per millisecond.
Real-world example
60 qt/h × 0.0002628758183 = 0.0157725491 mL/ms
60 quart per hours = 0.0157725491 milliliters per millisecond.

Frequently asked questions
How many milliliters per millisecond are in 1 quart per hours?
1 quart per hours equals 0.0002628758 milliliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert quart per hours to milliliter per millisecond?
Multiply the quart per hours value by 0.0002628758183. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per millisecond back to quart per hours?
Use the reverse factor: 1 milliliter per millisecond equals 3,804.077554 quart per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per hours?
Quart per Hours (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 quart per hours to milliliter per millisecond conversion exact?
Yes. Both quart per hours and milliliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0002628758183 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.
