I don't get that one. It might be just that you are used to it.

A meter is a slightly longish step.

A decimeter is the width of a hand.

A centimeter is the width of a pinky finger.

A milimeter is twice the thickness of your fingernail.

It is actually no less or more intuitive than the imperial system (except when it comes to calculations, unit conversion and interfacing with other SI units like Volts, Joules, Watts etc.) I feel very comfortable working with digits like 12.5 or 33.33. I think a lot of the imperial-versus-metric-debate boils down to the question how big your love for fractions is and how things are measured around you. If everything is built with 2 by 4 wood, then a metric system is inconvinient. If your hardware store sells 4x8cm wood, then going to inches would be inconvinient.

But they're not! My foot is 25cm, far from '1 foot'. My thumb is 1.5 cm wide, far from an inch. The metric system is actually much more human for me. And I never needed to measure 1/3rds to 0.02mm precision without a precise measurement instrument. And if exact precision doesn't matter then all these arguments about fractions are moot, too!

considering your foot is 2 standard deviations from the mean foot length, that hardly proves anything

Well it proves a lot in my opinion. Feet are really non uniform in length by a lot.

go to google and type "about definition"

You can't both say that meter isn't exact enough when meassuring 1/3 and also say that 25 mm wrong on a food is ok...

I didnt say exact, just not easily done aka intuitive. a concept probably lost on you ages ago
