About Converting Gallon per Hours to Megaliter per Seconds
Gallon per Hours and Megaliter 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
megaliter per seconds = gallon per hours × 1.051503e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per hours equals 0.00000105150327333 base units, and 1 megaliter per seconds equals 1000 base units, so dividing one by the other gives the direct gallon per hours-to-megaliter per seconds factor of 1.051503e-9.
Simple example
1 gal/h × 1.051503e-9 = 1.051503e-9 ML/s
1 gallon per hours = 1.051503e-9 megaliter per seconds.
Real-world example
60 gal/h × 1.051503e-9 = 6.30902e-8 ML/s
60 gallon per hours = 6.30902e-8 megaliter per seconds.

Frequently asked questions
How many megaliter per seconds are in 1 gallon per hours?
1 gallon per hours equals 1.051503e-9 megaliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to megaliter per seconds?
Multiply the gallon per hours value by 1.051503e-9. The converter above does this instantly to whatever precision you set.
How do I convert megaliter per seconds back to gallon per hours?
Use the reverse factor: 1 megaliter per seconds equals 951,019,388.5 gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
What is a megaliter per seconds?
Megaliter per Seconds (ML/s) is a unit of flow rate.
Is the gallon per hours to megaliter per seconds conversion exact?
Yes. Both gallon per hours and megaliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1.051503e-9 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.
