Measuring is a large part of my job, and I 90% of the time use Feet and Inches. I always think it's best to use the " or mm, as everyone knows what's been talked about. The lack of using them may have caused this space probe incident.
I live in England and are not happy about this metric thing being pushed upon us. I like lbs, not kgs, and inches, not centimetres.
Next thing we'll be using the Euro not good old pounds and pence. I hope the U.S. stays Imperial for ever ( though what's with this 7 pints in a Gallon lark!!! ).
Sick with it Mel, it's jollyfine.
