About Converting Oil barrel per Seconds to Imperial quarts per Millisecond
Oil barrel per Seconds and Imperial quart 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
imperial quarts per millisecond = oil barrel per seconds × 0.139889263018
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 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct oil barrel per seconds-to-imperial quart per millisecond factor of 0.139889263018.
Simple example
1 bbl/s × 0.139889263 = 0.139889263 imp qt/ms
1 oil barrel per seconds = 0.139889263 imperial quarts per millisecond.
Real-world example
60 bbl/s × 0.139889263 = 8.393355781 imp qt/ms
60 oil barrel per seconds = 8.393355781 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 oil barrel per seconds?
1 oil barrel per seconds equals 0.139889263 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert oil barrel per seconds to imperial quart per millisecond?
Multiply the oil barrel per seconds value by 0.139889263. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to oil barrel per seconds?
Use the reverse factor: 1 imperial quart per millisecond equals 7.148511461 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 imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/ms) is a unit of flow rate.
Is the oil barrel per seconds to imperial quart per millisecond conversion exact?
Yes. Both oil barrel per seconds and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.139889263 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.
