One liter per second is exactly 0.07004561995 acre-feet per day, so converting liters per second to acre-feet per day is a single multiplication. Enter any figure and the result appears as you type — the arithmetic runs in your browser, so nothing is sent anywhere.
Used for plumbing design and compressed air. Irrigation and reservoir release rates in the western United States.
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. Below the calculator there is a step table for the values people look up most, and a second table putting real volumetric flow figures into acre-feet per day so the number you get has something to be compared against.
The formula
liters per second- The amount you are converting, in liters per second
0.0700456199457- The exact number of acre-feet per day in one liter per second
acre-feet per day- The converted result
How it works, step by step
- Enter the value in liters per second.
- It is multiplied by 0.0700456199457, the exact factor between the two units.
- The answer is shown in acre-feet 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 acre-feet per day
A garden hose comes to about 0.3 L/s. Multiplying by the factor: 0.3 × 0.0700456 = 0.0210137 ac ft/d. Dividing the answer back by 0.0700456 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
A bathroom tap: 0.1 L/s in acre-feet per day
At 0.1 L/s (a bathroom tap), the same quantity in acre-feet per day is 0.1 × 0.0700456 = 0.00700456 ac ft/d. One liter per second is 0.0700456 acre-feet per day, so the numbers shrink as expected.
How to read your score
Frequently asked questions
How many acre-feet per day are in one liter per second?
Exactly 0.0700456199457. 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 acre-feet per day?
acre-feet per day = liters per second × 0.0700456199457. Reversed, liters per second = acre-feet per day ÷ 0.0700456199457, which is the same as multiplying by 14.2764101563.
Which is the bigger unit, the liter per second or the acre-foot per day?
The acre-foot per day. One liter per second is only 0.0700456 of a acre-foot per day, so it takes 14.2764 liters per second to make one acre-foot 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 acre-foot per day?
Irrigation and reservoir release rates in the western United States.
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 ac ft/d in my head?
Plenty of people do this in their head: divide by 14 instead of using the exact factor 0.07004561995. At 100 that shortcut gives 7.1428571 acre-feet per day, off by 0.1383 acre-feet per day or about 1.97%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
