How do I convert Miles to Millimeters?
It's 1,609,344 mm to the mile, exactly, so multiply by that. The factor comes from the mile being 1,609.344 m and each metre being 1,000 mm.
3 miles is 4,828,032 mm, and a 100-mile ultramarathon is 160,934,400 mm – not a figure anyone checks at the finish.
For a rough idea, 1.6 million mm per mile gets you within 0.6%.
