About Converting Hectoliter per Days to Imperial quarts per Millisecond
Hectoliter per Days 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 = hectoliter per days × 0.00000101837614953
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per days equals 0.00000115740740741 base units, and 1 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct hectoliter per days-to-imperial quart per millisecond factor of 0.00000101837614953.
Simple example
1 hL/d × 0.00000101837615 = 0.0000010184 imp qt/ms
1 hectoliter per days = 0.0000010184 imperial quarts per millisecond.
Real-world example
60 hL/d × 0.00000101837615 = 0.0000611026 imp qt/ms
60 hectoliter per days = 0.0000611026 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 hectoliter per days?
1 hectoliter per days equals 0.0000010184 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per days to imperial quart per millisecond?
Multiply the hectoliter per days value by 0.00000101837615. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to hectoliter per days?
Use the reverse factor: 1 imperial quart per millisecond equals 981,955.44 hectoliter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoliter per days?
Hectoliter per Days (hL/d) 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 hectoliter per days to imperial quart per millisecond conversion exact?
Yes. Both hectoliter per days and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00000101837615 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.
