About Converting Quart per Minutes to Imperial quarts per Millisecond
Quart per Minutes 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 = quart per minutes × 0.0000138779030771
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per minutes equals 0.0000157725491 base units, and 1 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct quart per minutes-to-imperial quart per millisecond factor of 0.0000138779030771.
Simple example
1 qt/min × 0.00001387790308 = 0.0000138779 imp qt/ms
1 quart per minutes = 0.0000138779 imperial quarts per millisecond.
Real-world example
60 qt/min × 0.00001387790308 = 0.0008326742 imp qt/ms
60 quart per minutes = 0.0008326742 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 quart per minutes?
1 quart per minutes equals 0.0000138779 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert quart per minutes to imperial quart per millisecond?
Multiply the quart per minutes value by 0.00001387790308. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to quart per minutes?
Use the reverse factor: 1 imperial quart per millisecond equals 72,056.99553 quart per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per minutes?
Quart per Minutes (qt/min) 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 minutes to imperial quart per millisecond conversion exact?
Yes. Both quart per minutes and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00001387790308 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.
