About Converting Hectoliter per Days to Hectoliters per Millisecond
Hectoliter per Days 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 = hectoliter per days × 1.157407e-8
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 hectoliter per millisecond equals 100 base units, so dividing one by the other gives the direct hectoliter per days-to-hectoliter per millisecond factor of 1.157407e-8.
Simple example
1 hL/d × 1.157407e-8 = 1.157407e-8 hL/ms
1 hectoliter per days = 1.157407e-8 hectoliters per millisecond.
Real-world example
60 hL/d × 1.157407e-8 = 6.944444e-7 hL/ms
60 hectoliter per days = 6.944444e-7 hectoliters per millisecond.

Frequently asked questions
How many hectoliters per millisecond are in 1 hectoliter per days?
1 hectoliter per days equals 1.157407e-8 hectoliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per days to hectoliter per millisecond?
Multiply the hectoliter per days value by 1.157407e-8. The converter above does this instantly to whatever precision you set.
How do I convert hectoliter per millisecond back to hectoliter per days?
Use the reverse factor: 1 hectoliter per millisecond equals 86,400,000 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 hectoliter per millisecond?
Hectoliter per Millisecond (hL/ms) is a unit of flow rate.
Is the hectoliter per days to hectoliter per millisecond conversion exact?
Yes. Both hectoliter per days and hectoliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.157407e-8 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.
