About Converting Hectoliter per Days to Liters per Millisecond
Hectoliter per Days and Liter 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
liters per millisecond = hectoliter per days × 0.00000115740740741
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 liter per millisecond equals 1 base unit, so dividing one by the other gives the direct hectoliter per days-to-liter per millisecond factor of 0.00000115740740741.
Simple example
1 hL/d × 0.000001157407407 = 0.0000011574 L/ms
1 hectoliter per days = 0.0000011574 liters per millisecond.
Real-world example
60 hL/d × 0.000001157407407 = 0.0000694444 L/ms
60 hectoliter per days = 0.0000694444 liters per millisecond.

Frequently asked questions
How many liters per millisecond are in 1 hectoliter per days?
1 hectoliter per days equals 0.0000011574 liters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per days to liter per millisecond?
Multiply the hectoliter per days value by 0.000001157407407. The converter above does this instantly to whatever precision you set.
How do I convert liter per millisecond back to hectoliter per days?
Use the reverse factor: 1 liter per millisecond equals 864,000 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 liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
Is the hectoliter per days to liter per millisecond conversion exact?
Yes. Both hectoliter per days and liter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000001157407407 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.
