About Converting Gallon per Seconds to Liter per Hours
Gallon per Seconds and Liter 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. Both are volumetric flow rate units.
Formula
liter per hours = gallon per seconds × 13627.4824224
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 liter per hours equals 2.777778e-7 base units, so dividing one by the other gives the direct gallon per seconds-to-liter per hours factor of 13627.4824224.
Simple example
1 gal/s × 13627.48242 = 13,627.48242 L/h
1 gallon per seconds = 13,627.48242 liter per hours.
Real-world example
60 gal/s × 13627.48242 = 817,648.9453 L/h
60 gallon per seconds = 817,648.9453 liter per hours.

Frequently asked questions
How many liter per hours are in 1 gallon per seconds?
1 gallon per seconds equals 13,627.48242 liter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to liter per hours?
Multiply the gallon per seconds value by 13627.48242. The converter above does this instantly to whatever precision you set.
How do I convert liter per hours back to gallon per seconds?
Use the reverse factor: 1 liter per hours equals 0.0000733811 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
What is a liter per hours?
Liter per Hours (L/h) is a unit of flow rate.
Is the gallon per seconds to liter per hours conversion exact?
Yes. Both gallon per seconds and liter per hours are defined by fixed standards rather than physical artifacts, so the factor of 13627.48242 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.
