About Converting Oil barrel per Seconds to Gallons per Millisecond
Oil barrel per Seconds and Gallon 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
gallons per millisecond = oil barrel per seconds × 0.042
This factor comes from each unit's defined relationship to the category's base unit: 1 oil barrel per seconds equals 0.158987294928 base units, and 1 gallon per millisecond equals 3.785411784 base units, so dividing one by the other gives the direct oil barrel per seconds-to-gallon per millisecond factor of 0.042.
Simple example
1 bbl/s × 0.042 = 0.042 gal/ms
1 oil barrel per seconds = 0.042 gallons per millisecond.
Real-world example
60 bbl/s × 0.042 = 2.52 gal/ms
60 oil barrel per seconds = 2.52 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 oil barrel per seconds?
1 oil barrel per seconds equals 0.042 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert oil barrel per seconds to gallon per millisecond?
Multiply the oil barrel per seconds value by 0.042. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to oil barrel per seconds?
Use the reverse factor: 1 gallon per millisecond equals 23.80952381 oil barrel per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a oil barrel per seconds?
Oil barrel per Seconds (bbl/s) is a unit of flow rate.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the oil barrel per seconds to gallon per millisecond conversion exact?
Yes. Both oil barrel per seconds and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.042 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.
