One hand is exactly 6.313131313e-05 miles, so converting hands to miles 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.
The statute mile: 5,280 feet, used for road distance in the US, UK and a handful of others. Exactly four inches, and still the only accepted way to state the height of a horse.
The mil and the millimetre are not the same thing and are out by a factor of about forty. A mil is one thousandth of an inch — 0.0254 mm — and a spec sheet that quotes film thickness in mils means the small unit. British drawings write the same size as "thou". The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in miles, so you can sanity-check whether your answer is a plausible size.

What does this quantity actually measure?
Both units measure length. 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 hand?
Exactly four inches, and still the only accepted way to state the height of a horse.
What is a mile?
The statute mile: 5,280 feet, used for road distance in the US, UK and a handful of others.
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 hh to mi in my head?
Plenty of people do this in their head: divide by 16,000 instead of using the exact factor 0.000063. At 100 that shortcut gives 0.00625 miles, off by 0.000063 miles or about 1.00%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
