Hi,
Have been able to follow topics by keeping handy a rule,tape,calipers and an old sliding metric conversion chart.

I do ok on everything except temperature.The old chart is not real detailed on the temp part.

What i can see is 0degF is -17celsius.This for me is way cold.

When you talk about -20,-30, how cold is this and what is actually happening outside.

I check temp observations for my state all the time,I like to see the summer and winter extremes.
What do you blokes experience in your summers and winters?
Thanks,
Beebloke
