I was referring to the use of MPH (which is probably wrong) and FPS mixed together. I don't care about bullet caliber being mixed mm and inch - I consider them to just be "a size" and not a measurement.

Isn't it just a constant ratio in either case? 1 mph === 1.46667 fps

  So? All units of a given quantity differ by just a constant factor [ignoring the affine units °C and °F]. But mixing mph and fps is just as disingenuous as, say, mixing mph and km/h. Nobody on Earth outside the US has any idea or intuition what the conversion factor between mph and fps is.

    Disingenuous was not the goal. I was in a hurry and didn't convert the last unit FPS after looking up the specifics.

      You've nothing to apologize for. MPH and FPS are both simple distance versus time measurements, both imperial, and trivially converted. Of course it's some non-US individual that has to complain about it, those are the only people who truly seem to care about what units are customary in the US. The rest of us just convert as necessary. Hell, just google search and have the answer in two seconds.

        Don't be ridiculous. It would be just as silly to have velocities in both m/s and km/h in a same paragraph. And many, many more people in the world know the conversion factor between those than between mph and fps. It's pretty bold of you to talk about 4% of the world's population as "the rest of us", but unfortunately it's to be expected from a certain type of American.

> I consider them to just be "a size" and not a measurement. You're right to consider it that way. In many cases, bullets aren't actually the size the name would suggest. For instance, .380 ACP is actually .355 inches (9mm) in diameter. 5.56x45mm is actually 5.7mm.

MPH is how they clocked it in the video. I should have converted it to FPS because that's the proper measurement for these sorts of things although I prefer or meters per second.
