About Converting Quart per Days to Cubic Millimeter per Hours
Quart per Days and Cubic Millimeter 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
cubic millimeter per hours = quart per days × 39431.37275
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 cubic millimeter per hours equals 2.777778e-13 base units, so dividing one by the other gives the direct quart per days-to-cubic millimeter per hours factor of 39431.37275.
Simple example
1 qt/d × 39431.37275 = 39,431.37275 mm3/h
1 quart per days = 39,431.37275 cubic millimeter per hours.
Real-world example
60 qt/d × 39431.37275 = 2,365,882.365 mm3/h
60 quart per days = 2,365,882.365 cubic millimeter per hours.

Frequently asked questions
How many cubic millimeter per hours are in 1 quart per days?
1 quart per days equals 39,431.37275 cubic millimeter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert quart per days to cubic millimeter per hours?
Multiply the quart per days value by 39431.37275. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per hours back to quart per days?
Use the reverse factor: 1 cubic millimeter per hours equals 0.0000253605 quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
What is a cubic millimeter per hours?
Cubic Millimeter per Hours (mm3/h) is a unit of flow rate.
Is the quart per days to cubic millimeter per hours conversion exact?
Yes. Both quart per days and cubic millimeter per hours are defined by fixed standards rather than physical artifacts, so the factor of 39431.37275 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.
