About Converting Cubic Millimeter per Hours to Quart per Days
Cubic Millimeter per Hours and Quart per Days 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
quart per days = cubic millimeter per hours × 0.0000253605170264
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per hours equals 2.777778e-13 base units, and 1 quart per days equals 1.095316e-8 base units, so dividing one by the other gives the direct cubic millimeter per hours-to-quart per days factor of 0.0000253605170264.
Simple example
1 mm3/h × 0.00002536051703 = 0.0000253605 qt/d
1 cubic millimeter per hours = 0.0000253605 quart per days.
Real-world example
60 mm3/h × 0.00002536051703 = 0.001521631 qt/d
60 cubic millimeter per hours = 0.001521631 quart per days.

Frequently asked questions
How many quart per days are in 1 cubic millimeter per hours?
1 cubic millimeter per hours equals 0.0000253605 quart per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per hours to quart per days?
Multiply the cubic millimeter per hours value by 0.00002536051703. The converter above does this instantly to whatever precision you set.
How do I convert quart per days back to cubic millimeter per hours?
Use the reverse factor: 1 quart per days equals 39,431.37275 cubic millimeter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per hours?
Cubic Millimeter per Hours (mm3/h) is a unit of flow rate.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
Is the cubic millimeter per hours to quart per days conversion exact?
Yes. Both cubic millimeter per hours and quart per days are defined by fixed standards rather than physical artifacts, so the factor of 0.00002536051703 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.
