You have to get rid of the conversions. Think metric. For some people it
takes time. We have been metric for 30 years, and it is seems to be only in
the last few years that people I deal with have been referring to the
weather in metric. We now think of a nice day as something in the 20s
rather than 70-80.

I stopped that a long time ago. When I am at the butcher shop I am more
likely to ask for a half kilo than a pound.
