About Converting Hectoliter per Days to Oil barrel per Days
Hectoliter per Days and Oil barrel per Days 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
oil barrel per days = hectoliter per days × 0.628981077043
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 oil barrel per days equals 0.00000184013072833 base units, so dividing one by the other gives the direct hectoliter per days-to-oil barrel per days factor of 0.628981077043.
Simple example
1 hL/d × 0.628981077 = 0.628981077 bbl/d
1 hectoliter per days = 0.628981077 oil barrel per days.
Real-world example
60 hL/d × 0.628981077 = 37.73886462 bbl/d
60 hectoliter per days = 37.73886462 oil barrel per days.

Frequently asked questions
How many oil barrel per days are in 1 hectoliter per days?
1 hectoliter per days equals 0.628981077 oil barrel per days, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per days to oil barrel per days?
Multiply the hectoliter per days value by 0.628981077. The converter above does this instantly to whatever precision you set.
How do I convert oil barrel per days back to hectoliter per days?
Use the reverse factor: 1 oil barrel per days equals 1.589872949 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 oil barrel per days?
Oil barrel per Days (bbl/d) is a unit of flow rate.
Is the hectoliter per days to oil barrel per days conversion exact?
Yes. Both hectoliter per days and oil barrel per days are defined by fixed standards rather than physical artifacts, so the factor of 0.628981077 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.
