About Converting Cubic Millimeter per Seconds to Cubic Meter per Days
Cubic Millimeter per Seconds and Cubic Meter 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 meter per days = cubic millimeter per seconds × 0.0000864
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 meter per days equals 0.0000115740740741 base units, so dividing one by the other gives the direct cubic millimeter per seconds-to-cubic meter per days factor of 0.0000864.
Simple example
1 mm3/s × 0.0000864 = 0.0000864 m3/d
1 cubic millimeter per seconds = 0.0000864 cubic meter per days.
Real-world example
60 mm3/s × 0.0000864 = 0.005184 m3/d
60 cubic millimeter per seconds = 0.005184 cubic meter per days.

Frequently asked questions
How many cubic meter per days are in 1 cubic millimeter per seconds?
1 cubic millimeter per seconds equals 0.0000864 cubic meter per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per seconds to cubic meter per days?
Multiply the cubic millimeter per seconds value by 0.0000864. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per days back to cubic millimeter per seconds?
Use the reverse factor: 1 cubic meter per days equals 11,574.07407 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 meter per days?
Cubic Meter per Days (m3/d) is a unit of flow rate.
Is the cubic millimeter per seconds to cubic meter per days conversion exact?
Yes. Both cubic millimeter per seconds and cubic meter per days are defined by fixed standards rather than physical artifacts, so the factor of 0.0000864 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.
