I'm curious, has there ever been an attempt at going metric in the US? e.g.
using Celsius? How do people feel about it?

In the early '70s, there were some Joint Resolutions which said,
basically, that the US should begin thinking about getting ready to
prepare for the possibility of considering a change to the metric
system. In the mid '70s I worked a job in a place that had international
sales and in light of the supposed atmosphere of metrification that was
spreading across the land I made a remark one day about the firm's units
of measurement. The foreman just about jumped down my throat. 'Why
should WE change?!?' he demanded. 'We're number one! Let the rest of
those countries [sic] change to OUR way!'

And in my firm, as in America generally, that was that.
