Emerson Unit 

An Emerson Unit defines the number of matches (Swedish standard) that need to be lit, and extinguished, in order to mask the smell of a fart.

This is similar to the Scoville Units, which indicate the number of drops of water to fully dilute the strength of a chilli.

That fart was so stinky it registered 10 Emerson Units! You need to lay off the cask beer man.
