About Converting Cubic foot per Seconds to Cubic Millimeter per Months
Cubic foot per Seconds and Cubic Millimeter per Months 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. Cubic foot per Seconds is most often used for the standard unit used by the us geological survey for reporting river and stream discharge at gauging stations.
Formula
cubic millimeter per months = cubic foot per seconds × 7.446611e+13
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per seconds equals 0.028316846592 base units, and 1 cubic millimeter per months equals 3.802649e-16 base units, so dividing one by the other gives the direct cubic foot per seconds-to-cubic millimeter per months factor of 7.446611e+13.
Simple example
1 ft3/s × 7.446611e+13 = 7.446611e+13 mm3/mo
1 cubic foot per seconds = 7.446611e+13 cubic millimeter per months.
Real-world example
60 ft3/s × 7.446611e+13 = 4.467967e+15 mm3/mo
60 cubic foot per seconds = 4.467967e+15 cubic millimeter per months.

Frequently asked questions
How many cubic millimeter per months are in 1 cubic foot per seconds?
1 cubic foot per seconds equals 7.446611e+13 cubic millimeter per months, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per seconds to cubic millimeter per months?
Multiply the cubic foot per seconds value by 7.446611e+13. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per months back to cubic foot per seconds?
Use the reverse factor: 1 cubic millimeter per months equals 1.342893e-14 cubic foot per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
What is a cubic millimeter per months?
Cubic Millimeter per Months (mm3/mo) is a unit of flow rate.
Is the cubic foot per seconds to cubic millimeter per months conversion exact?
Yes. Both cubic foot per seconds and cubic millimeter per months are defined by fixed standards rather than physical artifacts, so the factor of 7.446611e+13 used above is exact to as many digits as you choose to display.
Where is the cubic foot per seconds still used today?
United States
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.
