About Converting Gallon per Hours to Milliliter per Seconds
Gallon per Hours and Milliliter 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
milliliter per seconds = gallon per hours × 1.05150327333
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 milliliter per seconds equals 0.000001 base units, so dividing one by the other gives the direct gallon per hours-to-milliliter per seconds factor of 1.05150327333.
Simple example
1 gal/h × 1.051503273 = 1.051503273 mL/s
1 gallon per hours = 1.051503273 milliliter per seconds.
Real-world example
60 gal/h × 1.051503273 = 63.0901964 mL/s
60 gallon per hours = 63.0901964 milliliter per seconds.

Frequently asked questions
How many milliliter per seconds are in 1 gallon per hours?
1 gallon per hours equals 1.051503273 milliliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to milliliter per seconds?
Multiply the gallon per hours value by 1.051503273. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per seconds back to gallon per hours?
Use the reverse factor: 1 milliliter per seconds equals 0.9510193885 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 milliliter per seconds?
Milliliter per Seconds (mL/s) is a unit of flow rate.
Is the gallon per hours to milliliter per seconds conversion exact?
Yes. Both gallon per hours and milliliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1.051503273 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.
