About Converting Gallon per Days to Liter per Hours
Gallon per Days 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 days × 0.157725491
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 liter per hours equals 2.777778e-7 base units, so dividing one by the other gives the direct gallon per days-to-liter per hours factor of 0.157725491.
Simple example
1 gal/d × 0.157725491 = 0.157725491 L/h
1 gallon per days = 0.157725491 liter per hours.
Real-world example
60 gal/d × 0.157725491 = 9.46352946 L/h
60 gallon per days = 9.46352946 liter per hours.

Frequently asked questions
How many liter per hours are in 1 gallon per days?
1 gallon per days equals 0.157725491 liter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to liter per hours?
Multiply the gallon per days value by 0.157725491. The converter above does this instantly to whatever precision you set.
How do I convert liter per hours back to gallon per days?
Use the reverse factor: 1 liter per hours equals 6.340129257 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) 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 days to liter per hours conversion exact?
Yes. Both gallon per days and liter per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.157725491 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.
