About Converting Oil barrel per Hours to Gallon per Hours
Oil barrel per Hours and Gallon 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
gallon per hours = oil barrel per hours × 42
This factor comes from each unit's defined relationship to the category's base unit: 1 oil barrel per hours equals 0.00004416313748 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct oil barrel per hours-to-gallon per hours factor of 42.
Simple example
1 bbl/h × 42 = 42 gal/h
1 oil barrel per hours = 42 gallon per hours.
Real-world example
60 bbl/h × 42 = 2,520 gal/h
60 oil barrel per hours = 2,520 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 oil barrel per hours?
1 oil barrel per hours equals 42 gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert oil barrel per hours to gallon per hours?
Multiply the oil barrel per hours value by 42. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to oil barrel per hours?
Use the reverse factor: 1 gallon per hours equals 0.0238095238 oil barrel per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a oil barrel per hours?
Oil barrel per Hours (bbl/h) is a unit of flow rate.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the oil barrel per hours to gallon per hours conversion exact?
Yes. Both oil barrel per hours and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 42 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.
