About Converting Milliliter per Hours to Quarts per Millisecond
Milliliter per Hours and Quart 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
quarts per millisecond = milliliter per hours × 2.935245e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per hours equals 2.777778e-10 base units, and 1 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct milliliter per hours-to-quart per millisecond factor of 2.935245e-10.
Simple example
1 mL/h × 2.935245e-10 = 2.935245e-10 qt/ms
1 milliliter per hours = 2.935245e-10 quarts per millisecond.
Real-world example
60 mL/h × 2.935245e-10 = 1.761147e-8 qt/ms
60 milliliter per hours = 1.761147e-8 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 milliliter per hours?
1 milliliter per hours equals 2.935245e-10 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to quart per millisecond?
Multiply the milliliter per hours value by 2.935245e-10. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to milliliter per hours?
Use the reverse factor: 1 quart per millisecond equals 3,406,870,606 milliliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per hours?
Milliliter per Hours (mL/h) is a unit of flow rate.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the milliliter per hours to quart per millisecond conversion exact?
Yes. Both milliliter per hours and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.935245e-10 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.
