About Converting Quarts per Millisecond to Oil barrel per Hours
Quart per Millisecond 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 = quarts per millisecond × 21428.5714286
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per millisecond equals 0.946352946 base units, and 1 oil barrel per hours equals 0.00004416313748 base units, so dividing one by the other gives the direct quart per millisecond-to-oil barrel per hours factor of 21428.5714286.
Simple example
1 qt/ms × 21428.57143 = 21,428.57143 bbl/h
1 quart per millisecond = 21,428.57143 oil barrel per hours.
Real-world example
60 qt/ms × 21428.57143 = 1,285,714.286 bbl/h
60 quarts per millisecond = 1,285,714.286 oil barrel per hours.

Frequently asked questions
How many oil barrel per hours are in 1 quart per millisecond?
1 quart per millisecond equals 21,428.57143 oil barrel per hours, using the exact defined conversion factor rather than an estimate.
How do I convert quart per millisecond to oil barrel per hours?
Multiply the quart per millisecond value by 21428.57143. The converter above does this instantly to whatever precision you set.
How do I convert oil barrel per hours back to quart per millisecond?
Use the reverse factor: 1 oil barrel per hours equals 0.0000466667 quarts per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) 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 quart per millisecond to oil barrel per hours conversion exact?
Yes. Both quart per millisecond and oil barrel per hours are defined by fixed standards rather than physical artifacts, so the factor of 21428.57143 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.
