To convert miles to picas, multiply by 380,160. That factor is the whole relationship: both units measure length, so the conversion is a proportion with no offset and no substance-specific constant.
Twelve points, or 1/6 inch — the column-width unit of print layout. The statute mile: 5,280 feet, used for road distance in the US, UK and a handful of others.
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 picas, so you can sanity-check whether your answer is a plausible size.

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 mi to pica in my head?
Plenty of people do this in their head: multiply by 380,000 instead of using the exact factor 380,160. At 100 that shortcut gives 38,000,000 picas, off by 16000.000000 picas or about 0.04%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
