About Converting Cup per Minutes to Cubic Meter per Seconds
Cup per Minutes and Cubic Meter per Seconds 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 seconds = cup per minutes × 0.000003943137275
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per minutes equals 0.000003943137275 base units, and 1 cubic meter per seconds equals 1 base unit, so dividing one by the other gives the direct cup per minutes-to-cubic meter per seconds factor of 0.000003943137275.
Simple example
1 cup/min × 0.000003943137275 = 0.0000039431 m3/s
1 cup per minutes = 0.0000039431 cubic meter per seconds.
Real-world example
60 cup/min × 0.000003943137275 = 0.0002365882 m3/s
60 cup per minutes = 0.0002365882 cubic meter per seconds.

Frequently asked questions
How many cubic meter per seconds are in 1 cup per minutes?
1 cup per minutes equals 0.0000039431 cubic meter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cup per minutes to cubic meter per seconds?
Multiply the cup per minutes value by 0.000003943137275. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per seconds back to cup per minutes?
Use the reverse factor: 1 cubic meter per seconds equals 253,605.1703 cup per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per minutes?
Cup per Minutes (cup/min) is a unit of flow rate.
What is a cubic meter per seconds?
Cubic Meter per Seconds (m3/s) measures volumetric flow rate. The SI coherent unit for volumetric flow rate — one cubic meter of volume passing a point every second. It is classified as a SI coherent derived unit.
Is the cup per minutes to cubic meter per seconds conversion exact?
Yes. Both cup per minutes and cubic meter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.000003943137275 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.
