To convert acre-feet per day to milliliters per minute, multiply by 856,584.6094. That factor is the whole relationship: both units measure volumetric flow, so the conversion is a proportion with no offset and no substance-specific constant.
Irrigation and reservoir release rates in the western United States. Laboratory and infusion flow: HPLC pumps and syringe drivers are set in mL/min.
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 milliliters per minute, so you can sanity-check whether your answer is a plausible size.
The formula
acre-feet per day- The amount you are converting, in acre-feet per day
856,584.60938- The exact number of milliliters per minute in one acre-foot per day
milliliters per minute- The converted result
How it works, step by step
- Enter the value in acre-feet per day.
- It is multiplied by 856,584.60938, the exact factor between the two units.
- The answer is shown in milliliters per minute, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
A fire hydrant: 4.2 ac ft/d in milliliters per minute
Take a fire hydrant, roughly 4.2 ac ft/d. The conversion is a single multiplication — 4.2 × 856,585 — giving 3.59766e+06 mL/min. Because the relationship is proportional, doubling the input doubles the answer to 7.19531e+06 mL/min.
A shower head: 0.0112 ac ft/d in milliliters per minute
A shower head comes to about 0.0112 ac ft/d. Multiplying by the factor: 0.0112 × 856,585 = 9593.75 mL/min. Dividing the answer back by 856,585 returns the figure you started with, which is the quickest way to check you have the factor the right way up.

Frequently asked questions
How many milliliters per minute are in one acre-foot per day?
Exactly 856,584.60938. 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 acre-feet per day to milliliters per minute?
milliliters per minute = acre-feet per day × 856,584.60938. Reversed, acre-feet per day = milliliters per minute ÷ 856,584.60938, which is the same as multiplying by 1.1674269991e-06.
Which is the bigger unit, the acre-foot per day or the milliliter per minute?
The acre-foot per day. One acre-foot per day equals 856,585 milliliters per minute.
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 acre-foot per day?
Irrigation and reservoir release rates in the western United States.
What is a milliliter per minute?
Laboratory and infusion flow: HPLC pumps and syringe drivers are set in mL/min.
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 ac ft/d to mL/min in my head?
Plenty of people do this in their head: multiply by 860,000 instead of using the exact factor 856,584.6094. At 100 that shortcut gives 86,000,000 milliliters per minute, off by 341539.061961 milliliters per minute or about 0.40%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
