One smoot is 5 feet 7 inches long, which is about 1.70 meters.

This quirky unit comes from MIT students measuring the length of the Harvard Bridge in 1958 using the height of a student named Oliver Smoot as their ruler.

The bridge was famously recorded as “364.4 smoots ± one ear,” a playful nod to measurement error.

TL;DR:

  • 1 smoot = 5 ft 7 in.
  • ≈ 67 inches ≈ 1.7018 meters.
