About Converting Quart per Minutes to Hectoliters per Millisecond
Quart per Minutes and Hectoliter 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
hectoliters per millisecond = quart per minutes × 1.577255e-7
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 hectoliter per millisecond equals 100 base units, so dividing one by the other gives the direct quart per minutes-to-hectoliter per millisecond factor of 1.577255e-7.
Simple example
1 qt/min × 1.577255e-7 = 1.577255e-7 hL/ms
1 quart per minutes = 1.577255e-7 hectoliters per millisecond.
Real-world example
60 qt/min × 1.577255e-7 = 0.0000094635 hL/ms
60 quart per minutes = 0.0000094635 hectoliters per millisecond.

Frequently asked questions
How many hectoliters per millisecond are in 1 quart per minutes?
1 quart per minutes equals 1.577255e-7 hectoliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert quart per minutes to hectoliter per millisecond?
Multiply the quart per minutes value by 1.577255e-7. The converter above does this instantly to whatever precision you set.
How do I convert hectoliter per millisecond back to quart per minutes?
Use the reverse factor: 1 hectoliter per millisecond equals 6,340,129.257 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 hectoliter per millisecond?
Hectoliter per Millisecond (hL/ms) is a unit of flow rate.
Is the quart per minutes to hectoliter per millisecond conversion exact?
Yes. Both quart per minutes and hectoliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.577255e-7 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.
