About Converting Oil barrel per Hours to Oil barrels per Millisecond
Oil barrel per Hours and Oil barrel 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
oil barrels per millisecond = oil barrel per hours × 2.777778e-7
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 oil barrel per millisecond equals 158.987294928 base units, so dividing one by the other gives the direct oil barrel per hours-to-oil barrel per millisecond factor of 2.777778e-7.
Simple example
1 bbl/h × 2.777778e-7 = 2.777778e-7 bbl/ms
1 oil barrel per hours = 2.777778e-7 oil barrels per millisecond.
Real-world example
60 bbl/h × 2.777778e-7 = 0.0000166667 bbl/ms
60 oil barrel per hours = 0.0000166667 oil barrels per millisecond.

Frequently asked questions
How many oil barrels per millisecond are in 1 oil barrel per hours?
1 oil barrel per hours equals 2.777778e-7 oil barrels per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert oil barrel per hours to oil barrel per millisecond?
Multiply the oil barrel per hours value by 2.777778e-7. The converter above does this instantly to whatever precision you set.
How do I convert oil barrel per millisecond back to oil barrel per hours?
Use the reverse factor: 1 oil barrel per millisecond equals 3,600,000 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 oil barrel per millisecond?
Oil barrel per Millisecond (bbl/ms) is a unit of flow rate.
Is the oil barrel per hours to oil barrel per millisecond conversion exact?
Yes. Both oil barrel per hours and oil barrel per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.777778e-7 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.
