## ››Definition: 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). In October of 1958, fellow students helped Mr. Smoot measure the length of the bridge by placing him end to end and marking the increments. Oliver was a top student at MIT and went on to run NIST, the National Institute of Standards and Technology. The smoot is equal to his height (five feet and seven inches -- 1.70 m), and the bridge's length was measured to be "364.4 smoots plus one ear".
