About Converting Quart per Seconds to Milliliters per Millisecond
Quart per Seconds 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 seconds × 0.946352946
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per seconds equals 0.000946352946 base units, and 1 milliliter per millisecond equals 0.001 base units, so dividing one by the other gives the direct quart per seconds-to-milliliter per millisecond factor of 0.946352946.
Simple example
1 qt/s × 0.946352946 = 0.946352946 mL/ms
1 quart per seconds = 0.946352946 milliliters per millisecond.
Real-world example
60 qt/s × 0.946352946 = 56.78117676 mL/ms
60 quart per seconds = 56.78117676 milliliters per millisecond.

Frequently asked questions
How many milliliters per millisecond are in 1 quart per seconds?
1 quart per seconds equals 0.946352946 milliliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert quart per seconds to milliliter per millisecond?
Multiply the quart per seconds value by 0.946352946. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per millisecond back to quart per seconds?
Use the reverse factor: 1 milliliter per millisecond equals 1.056688209 quart per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per seconds?
Quart per Seconds (qt/s) 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 seconds to milliliter per millisecond conversion exact?
Yes. Both quart per seconds and milliliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.946352946 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.
