Weird Units Calculator — Smoots, Cubits, Furlongs & More
How many smoots is the Golden Gate Bridge? How many cubits is your house? Enter any distance in metres and convert it to eight unusual, archaic or quirky units — from the smoot (a unit invented at MIT in 1958) to the light year.

Convert metres to eight unusual units. 1 smoot = 1.7018 m; 1 cubit = 0.4572 m; 1 furlong = 201.168 m; 1 hand = 0.1016 m; 1 fathom = 1.8288 m; 1 chain = 20.1168 m; 1 league = 4 828.032 m. Default: 1 000 m ≈ 588 smoots, 4.97 furlongs, 546.8 fathoms, 49.7 chains.

How this is calculated
Most of these units were once genuinely used for everyday measurement before the metric system arrived. The hand (4 inches) has been used to measure horse height since at least the 16th century and is still the official unit in horse racing. The furlong (220 yards, originally the length a team of oxen could plough without resting) lives on in horse-racing distances and some Commonwealth land records. The chain (22 yards, invented by Edmund Gunter in 1620) was the standard surveying unit that produced the acre (10 chains × 1 chain). The fathom (6 feet) was the standard depth unit in marine navigation before SI. The league (3 miles) was a common travel-distance unit in pre-industrial Europe and famously used in Jules Verne's '20 000 Leagues Under the Sea'.
The cubit is one of the oldest known units of length — roughly the distance from elbow to fingertip (~18 inches). Different ancient cultures defined it slightly differently; this calculator uses the common cubit of exactly 18 inches (0.4572 m). The smoot is a humorous unit created in 1958 when MIT student Oliver Smoot lay down end-to-end to measure the Harvard Bridge in Cambridge, Massachusetts. The bridge is officially 364.4 ± 1 ear smoots long, and the paint markings are repainted annually by MIT students.
The light year (9.461 × 10¹⁵ m) is an astronomical distance unit equal to the distance light travels in one Julian year (365.25 days). For any distance on Earth, the light-year value will be an extremely small fraction — nanoscopic compared to interstellar scales.

The Harvard Bridge (MIT Bridge) in Cambridge, Massachusetts was measured at 364.4 ± 1 ear smoots in 1958 by Oliver Smoot and his fraternity brothers. 364.4 smoots × 1.7018 m ≈ 620.1 m. The markings are still repainted each year by MIT students.
Yes — in horse racing. Race distances in the United Kingdom, Ireland, the United States, Australia and other countries are still measured in furlongs (1 furlong = 201.168 m = ⅛ mile). A typical horse race is 6–20 furlongs. The furlong also appears in some US and UK land descriptions.
A Gunter's chain is exactly 22 yards (20.1168 m). It was the standard land-survey unit across the British Empire and the United States from the 17th century onward. 10 chains × 1 chain = 1 acre, and 80 chains = 1 mile. Most historical land records in the US, UK, Australia, Canada and India were recorded in chains and links (1 chain = 100 links).
