About Converting Oil barrel per Days to Quarts per Millisecond
Oil barrel per Days and 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
quarts per millisecond = oil barrel per days × 0.00000194444444444
This factor comes from each unit's defined relationship to the category's base unit: 1 oil barrel per days equals 0.00000184013072833 base units, and 1 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct oil barrel per days-to-quart per millisecond factor of 0.00000194444444444.
Simple example
1 bbl/d × 0.000001944444444 = 0.0000019444 qt/ms
1 oil barrel per days = 0.0000019444 quarts per millisecond.
Real-world example
60 bbl/d × 0.000001944444444 = 0.0001166667 qt/ms
60 oil barrel per days = 0.0001166667 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 oil barrel per days?
1 oil barrel per days equals 0.0000019444 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert oil barrel per days to quart per millisecond?
Multiply the oil barrel per days value by 0.000001944444444. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to oil barrel per days?
Use the reverse factor: 1 quart per millisecond equals 514,285.7143 oil barrel per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a oil barrel per days?
Oil barrel per Days (bbl/d) is a unit of flow rate.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the oil barrel per days to quart per millisecond conversion exact?
Yes. Both oil barrel per days and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000001944444444 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.
