>I think it actually is a US law enacted by Congress a while back, to go to "dual systems," in preparation for all-metric someday (I'll have to look this up, now I'm curious). Most commercial items in US seem to use both systems now, anyway, like the can of coke I'm drinking says "12 oz (355ml)", and the print-toner by me has "store at only between a-b degress F, c-d degrees C."
Somehow, that seems plain wrong to me. SI (metric) units should come first, and perhaps even in larger letters.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
