About Smoot

A smoot is a unit of distance (or "length", as physical scientists say) used for measuring the Harvard Bridge. It is named after an MIT fraternity pledge at Lambda Chi Alpha fraternity, Oliver R. Smoot (class of 1962), who in October, 1958 was rolled head over heels by his fraternity brothers to measure the length of the bridge. The smoot is equal to his height (five feet and seven inches -- 1.70 m), and the bridges length was measured to be "364.4 smoots plus one ear".

About Em

The em is a printers unit of relative distance. One em is the height of the type size (in points) being used. If 12 point type is being set, then one em is 12 points, and so on.
