This page converts liters per second into US gallons per day using the factor 22,824.47003, and shows the reverse figure alongside it. Both units measure volumetric flow, which is why one number does the whole job.
Used for plumbing design and compressed air. The rating unit for reverse-osmosis membranes and water demand.
Standard versus actual volume. Gas flow in CFM depends on pressure and temperature, which is why compressor ratings say SCFM and specify the reference conditions. Converting the number is exact; comparing two ratings measured at different conditions is not. The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in US gallons per day, so you can sanity-check whether your answer is a plausible size.
The formula
liters per second- The amount you are converting, in liters per second
22,824.4700307- The exact number of US gallons per day in one liter per second
US gallons per day- The converted result
How it works, step by step
- Enter the value in liters per second.
- It is multiplied by 22,824.4700307, the exact factor between the two units.
- The answer is shown in US gallons per day, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
A garden hose: 0.3 L/s in US gallons per day
Take a garden hose, roughly 0.3 L/s. The conversion is a single multiplication — 0.3 × 22,824.5 — giving 6847.34 GPD. Because the relationship is proportional, doubling the input doubles the answer to 13,694.7 GPD.
A bathroom tap: 0.1 L/s in US gallons per day
At 0.1 L/s (a bathroom tap), the same quantity in US gallons per day is 0.1 × 22,824.5 = 2282.45 GPD. One liter per second is 22,824.5 US gallons per day, so the numbers grow as expected.
How to read your score
Frequently asked questions
How many US gallons per day are in one liter per second?
Exactly 22,824.4700307. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert liters per second to US gallons per day?
US gallons per day = liters per second × 22,824.4700307. Reversed, liters per second = US gallons per day ÷ 22,824.4700307, which is the same as multiplying by 4.38126273536e-05.
Which is the bigger unit, the liter per second or the US gallon per day?
The liter per second. One liter per second equals 22,824.5 US gallons per day.
What does this quantity actually measure?
Both units measure volumetric flow. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a liter per second?
Used for plumbing design and compressed air.
What is a US gallon per day?
The rating unit for reverse-osmosis membranes and water demand.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
Is there a quick way to do L/s to GPD in my head?
Plenty of people do this in their head: multiply by 23,000 instead of using the exact factor 22,824.47003. At 100 that shortcut gives 2,300,000 US gallons per day, off by 17552.996926 US gallons per day or about 0.77%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
