| @Neilos: it's not only the names, the units themselves were more intuitive. The problem was, of course, that a foot was 32.5 cm in France, 30.5 cm in the UK, 27.9 cm in Spain, etc., so it was too complicated for trade, science, etc. A meter was a meter everywhere, but in the early 19th century nobody knew, even approximately, the length of a meter (to say that it was 1/40,000,000 of the circumference of the Earth was of little help to ordinary people). To know the approximate length of a foot you only had to look at your feet. |
