About Converting Cubic Millimeter per Days to Metric cup per Days
Cubic Millimeter per Days and Metric cup 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
metric cup per days = cubic millimeter per days × 0.000004
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per days equals 1.157407e-14 base units, and 1 metric cup per days equals 2.893519e-9 base units, so dividing one by the other gives the direct cubic millimeter per days-to-metric cup per days factor of 0.000004.
Simple example
1 mm3/d × 0.000004 = 0.000004 metric cup/d
1 cubic millimeter per days = 0.000004 metric cup per days.
Real-world example
60 mm3/d × 0.000004 = 0.00024 metric cup/d
60 cubic millimeter per days = 0.00024 metric cup per days.

Frequently asked questions
How many metric cup per days are in 1 cubic millimeter per days?
1 cubic millimeter per days equals 0.000004 metric cup per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per days to metric cup per days?
Multiply the cubic millimeter per days value by 0.000004. The converter above does this instantly to whatever precision you set.
How do I convert metric cup per days back to cubic millimeter per days?
Use the reverse factor: 1 metric cup per days equals 250,000 cubic millimeter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per days?
Cubic Millimeter per Days (mm3/d) is a unit of flow rate.
What is a metric cup per days?
Metric cup per Days (metric cup/d) is a unit of flow rate.
Is the cubic millimeter per days to metric cup per days conversion exact?
Yes. Both cubic millimeter per days and metric cup per days are defined by fixed standards rather than physical artifacts, so the factor of 0.000004 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.
