    To me the major advantage is that these units are the same everywhere. Many older measures have regional, national or application specific variations.

    A kilometer is always the same, a mile varies a bit, imperial, nautical, or railway ?
    A liter is likewise the same everywhere, whereas US and UK gallons are significantly different.
    Universal (almost) and consistency are the merits for me.

      For me it would be that the math is straightforward. Simple addition, subtraction, multiplication, and division would be so much easier to get right without having to deal with, for example, miles, feet, inches, and fractions of inches.

        That's it in a nutshell. Simpler.

          I would say full stroke for displacement but port-to-TDC for compression ratio.

            I believe your hope to keep American practice in measurement-standards is about to be dashed! Next month reps from 57 countries will meet in France to change SI-units in the most profound way since the French evolution!

              That makes sense: 12 lignes to the inch; 12 inches to the foot: magnitude of ten.

                Unless you're a surveyor, in which case there are only ten inches to the foot.

                  Like there were originally only ten months?

                    I don't recall, did anyone mention the furlong–firkin–fortnight system (https://en.wikipedia.org/wiki/FFF_system)? A microfortnight is rather close to one second and a millifurlong is almost 8" (or 20cm).
