About Converting Cubic Meter per Seconds to Gallon per Hours
Cubic Meter per Seconds and Gallon per Hours 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 most often used for used by hydrologists and water-resource engineers internationally to report river and reservoir discharge at large scales.
Formula
gallon per hours = cubic meter per seconds × 951019.388489
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 hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct cubic meter per seconds-to-gallon per hours factor of 951019.388489.
Simple example
1 m3/s × 951019.3885 = 951,019.3885 gal/h
1 cubic meter per seconds = 951,019.3885 gallon per hours.
Real-world example
60 m3/s × 951019.3885 = 57,061,163.31 gal/h
60 cubic meter per seconds = 57,061,163.31 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 cubic meter per seconds?
1 cubic meter per seconds equals 951,019.3885 gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per seconds to gallon per hours?
Multiply the cubic meter per seconds value by 951019.3885. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to cubic meter per seconds?
Use the reverse factor: 1 gallon per hours equals 0.0000010515 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 hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the cubic meter per seconds to gallon per hours conversion exact?
Yes. Both cubic meter per seconds and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 951019.3885 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.
