>We use Calories (ie kilo-calories). You won't hear the man in the street referring to Joules (or Ergs), esp. as most won't know what they are anyway. And "bar" for pressure.

Same over there, wherever one feels the pressure, one visits the bar :).

Jouls were a part of the effort to put everything into IS units, presumably to facilitate the switch into computers... until we succumbed to the lure of the Western-type laziness and saw that it's easier to change code than to change people's habits. So while we're generally metric, there are a few areas where some old units are used - inches for plumbing (but not sewers), measuring land area - while everyone knows ares and hectares, you aren't a pro peasant if you use those; you'd say "two chains of land" or "a morning and a half of land".

Anyways, whenever a new unit of measure was pushed, whoever tried to use it would get a "just tell me in old dinars, OK?".
