About Converting Oil barrel per Days to Hectoliters per Millisecond
Oil barrel 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 = oil barrel per days × 1.840131e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 oil barrel per days equals 0.00000184013072833 base units, and 1 hectoliter per millisecond equals 100 base units, so dividing one by the other gives the direct oil barrel per days-to-hectoliter per millisecond factor of 1.840131e-8.
Simple example
1 bbl/d × 1.840131e-8 = 1.840131e-8 hL/ms
1 oil barrel per days = 1.840131e-8 hectoliters per millisecond.
Real-world example
60 bbl/d × 1.840131e-8 = 0.0000011041 hL/ms
60 oil barrel per days = 0.0000011041 hectoliters per millisecond.

Frequently asked questions
How many hectoliters per millisecond are in 1 oil barrel per days?
1 oil barrel per days equals 1.840131e-8 hectoliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert oil barrel per days to hectoliter per millisecond?
Multiply the oil barrel per days value by 1.840131e-8. The converter above does this instantly to whatever precision you set.
How do I convert hectoliter per millisecond back to oil barrel per days?
Use the reverse factor: 1 hectoliter per millisecond equals 54,343,965.06 oil barrel per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a oil barrel per days?
Oil barrel per Days (bbl/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 oil barrel per days to hectoliter per millisecond conversion exact?
Yes. Both oil barrel per days and hectoliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.840131e-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.
