Imperial Units

Just when I thought I knew all of the imperial units I heard Matt Parker (Standup Maths) list them all, even the more obscure ones, in this wonderful monologue. When you hear their names and their relative sizes you cannot help but be grateful for the metric system which is more common today.

More or Less Podcast Matt Parker's Website Transum Podcast

This audio excerpt is from an excellent podcast from BBC Radio 4 called More or Less: Behind the Stats in which Tim Harford tries to make sense of the statistics which surround us. It's well worth a listen if you have an interest in mathematics and statistics and provides real world examples of the maths we learn in school.
