About Converting Cubic Meter per Hours to Gallon per Seconds
Cubic Meter per Hours and Gallon 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. Cubic Meter per Hours is most often used for hvac equipment airflow and liquid-flow ratings.
Formula
gallon per seconds = cubic meter per hours × 0.073381125655
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per hours equals 0.000277777777778 base units, and 1 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct cubic meter per hours-to-gallon per seconds factor of 0.073381125655.
Simple example
1 m3/h × 0.07338112566 = 0.0733811257 gal/s
1 cubic meter per hours = 0.0733811257 gallon per seconds.
Real-world example
60 m3/h × 0.07338112566 = 4.402867539 gal/s
60 cubic meter per hours = 4.402867539 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 cubic meter per hours?
1 cubic meter per hours equals 0.0733811257 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per hours to gallon per seconds?
Multiply the cubic meter per hours value by 0.07338112566. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to cubic meter per hours?
Use the reverse factor: 1 gallon per seconds equals 13.62748242 cubic meter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per hours?
Cubic Meter per Hours (m3/h) measures volumetric flow rate. One cubic meter of volume passing a point every hour — a common scale for equipment and system flow ratings. It is classified as a metric derived flow-rate unit.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the cubic meter per hours to gallon per seconds conversion exact?
Yes. Both cubic meter per hours and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.07338112566 used above is exact to as many digits as you choose to display.
Where is the cubic meter per hours still used today?
Standard flow-rate unit for HVAC and industrial equipment ratings internationally, outside the US
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.
