About Converting Deciliter per Days to Quarts per Millisecond
Deciliter 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 = deciliter per days × 1.223019e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 deciliter per days equals 1.157407e-9 base units, and 1 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct deciliter per days-to-quart per millisecond factor of 1.223019e-9.
Simple example
1 dL/d × 1.223019e-9 = 1.223019e-9 qt/ms
1 deciliter per days = 1.223019e-9 quarts per millisecond.
Real-world example
60 dL/d × 1.223019e-9 = 7.338113e-8 qt/ms
60 deciliter per days = 7.338113e-8 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 deciliter per days?
1 deciliter per days equals 1.223019e-9 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert deciliter per days to quart per millisecond?
Multiply the deciliter per days value by 1.223019e-9. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to deciliter per days?
Use the reverse factor: 1 quart per millisecond equals 817,648,945.3 deciliter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a deciliter per days?
Deciliter per Days (dL/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 deciliter per days to quart per millisecond conversion exact?
Yes. Both deciliter per days and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.223019e-9 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.
