Good work. Perhaps you can steal this idea: Metric intervention https://userscripts-mirror.org/scripts/show/130277 https://userscripts-mirror.org/scripts/show/130277 > Converting that old French system the Brits are still using to the metric standard of science. ~ foot, inch (00',00",00'00,00'00"), yard, mile, stone, Pound-mass/Lbs., Gallon ~ It will totally convert something heretical like: 1'23 1/4" x 2'12 5/8" into something elegant and civilized like 89.535 cm x 93.0275 cm This (uhm) didn't take a year to make but it was rather useful when I needed it.
