About Converting Hectoliter per Days to Fluid ounces per Millisecond
Hectoliter per Days and Fluid ounce 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
fluid ounces per millisecond = hectoliter per days × 0.0000391366003494
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 fluid ounce per millisecond equals 0.0295735295625 base units, so dividing one by the other gives the direct hectoliter per days-to-fluid ounce per millisecond factor of 0.0000391366003494.
Simple example
1 hL/d × 0.00003913660035 = 0.0000391366 fl oz/ms
1 hectoliter per days = 0.0000391366 fluid ounces per millisecond.
Real-world example
60 hL/d × 0.00003913660035 = 0.002348196 fl oz/ms
60 hectoliter per days = 0.002348196 fluid ounces per millisecond.

Frequently asked questions
How many fluid ounces per millisecond are in 1 hectoliter per days?
1 hectoliter per days equals 0.0000391366 fluid ounces per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per days to fluid ounce per millisecond?
Multiply the hectoliter per days value by 0.00003913660035. The converter above does this instantly to whatever precision you set.
How do I convert fluid ounce per millisecond back to hectoliter per days?
Use the reverse factor: 1 fluid ounce per millisecond equals 25,551.52954 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 fluid ounce per millisecond?
Fluid ounce per Millisecond (fl oz/ms) is a unit of flow rate.
Is the hectoliter per days to fluid ounce per millisecond conversion exact?
Yes. Both hectoliter per days and fluid ounce per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00003913660035 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.
