About Converting Gallon per Days to Oil barrel per Hours
Gallon per Days and Oil barrel per Hours 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 hours = gallon per days × 0.000992063492063
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 oil barrel per hours equals 0.00004416313748 base units, so dividing one by the other gives the direct gallon per days-to-oil barrel per hours factor of 0.000992063492063.
Simple example
1 gal/d × 0.0009920634921 = 0.0009920635 bbl/h
1 gallon per days = 0.0009920635 oil barrel per hours.
Real-world example
60 gal/d × 0.0009920634921 = 0.0595238095 bbl/h
60 gallon per days = 0.0595238095 oil barrel per hours.

How do I convert oil barrel per hours back to gallon per days?
Use the reverse factor: 1 oil barrel per hours equals 1,008 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a oil barrel per hours?
Oil barrel per Hours (bbl/h) is a unit of flow rate.
Is the gallon per days to oil barrel per hours conversion exact?
Yes. Both gallon per days and oil barrel per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.0009920634921 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.
