About Converting Cubic Millimeter per Seconds to Cubic inch per Days
Cubic Millimeter per Seconds and Cubic inch 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 inch per days = cubic millimeter per seconds × 5.27245148978
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per seconds equals 1e-9 base units, and 1 cubic inch per days equals 1.896651e-10 base units, so dividing one by the other gives the direct cubic millimeter per seconds-to-cubic inch per days factor of 5.27245148978.
Simple example
1 mm3/s × 5.27245149 = 5.27245149 in3/d
1 cubic millimeter per seconds = 5.27245149 cubic inch per days.
Real-world example
60 mm3/s × 5.27245149 = 316.3470894 in3/d
60 cubic millimeter per seconds = 316.3470894 cubic inch per days.

Frequently asked questions
How many cubic inch per days are in 1 cubic millimeter per seconds?
1 cubic millimeter per seconds equals 5.27245149 cubic inch per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per seconds to cubic inch per days?
Multiply the cubic millimeter per seconds value by 5.27245149. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per days back to cubic millimeter per seconds?
Use the reverse factor: 1 cubic inch per days equals 0.1896650926 cubic millimeter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per seconds?
Cubic Millimeter per Seconds (mm3/s) is a unit of flow rate.
What is a cubic inch per days?
Cubic inch per Days (in3/d) is a unit of flow rate.
Is the cubic millimeter per seconds to cubic inch per days conversion exact?
Yes. Both cubic millimeter per seconds and cubic inch per days are defined by fixed standards rather than physical artifacts, so the factor of 5.27245149 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.
