About Converting Hectoliter per Hours to Quarts per Millisecond
Hectoliter 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 = hectoliter per hours × 0.000029352450262
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per hours equals 0.0000277777777778 base units, and 1 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct hectoliter per hours-to-quart per millisecond factor of 0.000029352450262.
Simple example
1 hL/h × 0.00002935245026 = 0.0000293525 qt/ms
1 hectoliter per hours = 0.0000293525 quarts per millisecond.
Real-world example
60 hL/h × 0.00002935245026 = 0.001761147 qt/ms
60 hectoliter per hours = 0.001761147 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 hectoliter per hours?
1 hectoliter per hours equals 0.0000293525 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per hours to quart per millisecond?
Multiply the hectoliter per hours value by 0.00002935245026. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to hectoliter per hours?
Use the reverse factor: 1 quart per millisecond equals 34,068.70606 hectoliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoliter per hours?
Hectoliter per Hours (hL/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 hectoliter per hours to quart per millisecond conversion exact?
Yes. Both hectoliter per hours and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00002935245026 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.
