About Converting Cup per Days to Cubic Millimeter per Days
Cup per Days and Cubic Millimeter 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
cubic millimeter per days = cup per days × 236588.2365
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per days equals 2.73829e-9 base units, and 1 cubic millimeter per days equals 1.157407e-14 base units, so dividing one by the other gives the direct cup per days-to-cubic millimeter per days factor of 236588.2365.
Simple example
1 cup/d × 236588.2365 = 236,588.2365 mm3/d
1 cup per days = 236,588.2365 cubic millimeter per days.
Real-world example
60 cup/d × 236588.2365 = 14,195,294.19 mm3/d
60 cup per days = 14,195,294.19 cubic millimeter per days.

Frequently asked questions
How many cubic millimeter per days are in 1 cup per days?
1 cup per days equals 236,588.2365 cubic millimeter per days, using the exact defined conversion factor rather than an estimate.
How do I convert cup per days to cubic millimeter per days?
Multiply the cup per days value by 236588.2365. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per days back to cup per days?
Use the reverse factor: 1 cubic millimeter per days equals 0.0000042268 cup per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
What is a cubic millimeter per days?
Cubic Millimeter per Days (mm3/d) is a unit of flow rate.
Is the cup per days to cubic millimeter per days conversion exact?
Yes. Both cup per days and cubic millimeter per days are defined by fixed standards rather than physical artifacts, so the factor of 236588.2365 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.
