About Converting Quarts per Millisecond to Imperial quarts per Millisecond
Quart per Millisecond and Imperial 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
imperial quarts per millisecond = quarts per millisecond × 0.832674184629
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per millisecond equals 0.946352946 base units, and 1 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct quart per millisecond-to-imperial quart per millisecond factor of 0.832674184629.
Simple example
1 qt/ms × 0.8326741846 = 0.8326741846 imp qt/ms
1 quart per millisecond = 0.8326741846 imperial quarts per millisecond.
Real-world example
60 qt/ms × 0.8326741846 = 49.96045108 imp qt/ms
60 quarts per millisecond = 49.96045108 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 quart per millisecond?
1 quart per millisecond equals 0.8326741846 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert quart per millisecond to imperial quart per millisecond?
Multiply the quart per millisecond value by 0.8326741846. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to quart per millisecond?
Use the reverse factor: 1 imperial quart per millisecond equals 1.200949926 quarts per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
What is a imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/ms) is a unit of flow rate.
Is the quart per millisecond to imperial quart per millisecond conversion exact?
Yes. Both quart per millisecond and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.8326741846 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.
