One liter per hour is exactly 1.945711665e-05 acre-feet per day, so converting liters per hour 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.
Irrigation and reservoir release rates in the western United States. The rating unit for dosing pumps, drip irrigation and small boilers.
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. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into acre-feet per day, which is usually more useful than the bare number.
The formula
liters per hour- The amount you are converting, in liters per hour
1.94571166516e-05- The exact number of acre-feet per day in one liter per hour
acre-feet per day- The converted result
How it works, step by step
- Enter the value in liters per hour.
- It is multiplied by 1.94571166516e-05, 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 shower head: 576 L/h in acre-feet per day
Take a shower head, roughly 576 L/h. The conversion is a single multiplication — 576 × 1.94571e-05 — giving 0.0112073 ac ft/d. Because the relationship is proportional, doubling the input doubles the answer to 0.0224146 ac ft/d.
A dripping tap: 0.36 L/h in acre-feet per day
At 0.36 L/h (a dripping tap), the same quantity in acre-feet per day is 0.36 × 1.94571e-05 = 7.00456e-06 ac ft/d. One liter per hour is 1.94571e-05 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 hour?
Exactly 1.94571166516e-05. 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 hour to acre-feet per day?
acre-feet per day = liters per hour × 1.94571166516e-05. Reversed, liters per hour = acre-feet per day ÷ 1.94571166516e-05, which is the same as multiplying by 51,395.0765628.
Which is the bigger unit, the liter per hour or the acre-foot per day?
The acre-foot per day. One liter per hour is only 1.94571e-05 of a acre-foot per day, so it takes 51,395.1 liters per hour 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 hour?
The rating unit for dosing pumps, drip irrigation and small boilers.
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/h to ac ft/d in my head?
Plenty of people do this in their head: divide by 50,000 instead of using the exact factor 0.000019. At 100 that shortcut gives 0.002 acre-feet per day, off by 0.000054 acre-feet per day or about 2.79%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
