About Converting Cubic Meter per Seconds to Gallon per Minutes
Cubic Meter per Seconds and Gallon per Minutes 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 Meter per Seconds is typically associated with used internationally in hydrology and large-scale water-resource engineering, while Gallon per Minutes is typically associated with united States (plumbing, pump, and irrigation industry standard).
Formula
gallon per minutes = cubic meter per seconds × 15850.3231415
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per seconds equals 1 base unit, and 1 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct cubic meter per seconds-to-gallon per minutes factor of 15850.3231415.
Simple example
1 m3/s × 15850.32314 = 15,850.32314 gal/min
1 cubic meter per seconds = 15,850.32314 gallon per minutes.
Real-world example
60 m3/s × 15850.32314 = 951,019.3885 gal/min
60 cubic meter per seconds = 951,019.3885 gallon per minutes.

Frequently asked questions
How many gallon per minutes are in 1 cubic meter per seconds?
1 cubic meter per seconds equals 15,850.32314 gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per seconds to gallon per minutes?
Multiply the cubic meter per seconds value by 15850.32314. The converter above does this instantly to whatever precision you set.
How do I convert gallon per minutes back to cubic meter per seconds?
Use the reverse factor: 1 gallon per minutes equals 0.0000630902 cubic meter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
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.
What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
Is the cubic meter per seconds to gallon per minutes conversion exact?
Yes. Both cubic meter per seconds and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 15850.32314 used above is exact to as many digits as you choose to display.
Where is the cubic meter per seconds still used today?
Used internationally in hydrology and large-scale water-resource engineering
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.
