An adult human foot is about 28 cm (11 in) long. The decimetre (SI symbol: dm) is a unit of length in the metric system equal to 10 −1 metres ( 1 / 10 m = 0.1 m). To help compare different orders of magnitude, this section lists lengths between 10 centimeters and 100 centimeters (10 −1 meter and 1 meter).
The Egyptian equivalent of the foot—a measure of four palms or 16 digits—was known as the djeser and has been reconstructed as about 30 cm (11.8 in). The Greek foot (πούς, pous) had a length of 1 / 600 of a stadion, [12] one stadion being about 181.2 m (594 ft); [13] therefore a foot was, at the time, about 302 mm (11.9 in). Its ...
The metre (or meter in US spelling; symbol: m) is the base unit of length in the International System of Units (SI). Since 2019, the metre has been defined as the length of the path travelled by light in vacuum during a time interval of 1 / 299 792 458 of a second, where the second is defined by a hyperfine transition frequency of caesium.
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. [2] [3] [4] Historically, it was defined as the meridian arc length corresponding to one minute ( 1 / 60 of a degree) of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical miles (that is 60 minutes × 360 degrees).

The Árbol del Tule in Santa Maria del Tule, Oaxaca, Mexico (Taxodium mucronatum) has a girth of 119.8 feet (36.5 m) and a height of 116.1 feet (35.4 m), with a 144-foot (43.9 m) wide crown as measured by Dr. Robert Van Pelt in 2005. The Tule tree therefore has a diameter of 38.1 feet (11.61 m) as extrapolated from the tape wrap values.
The 74-year-old comedian recently “fell 60 feet” down a hill outside a hotel, he shared. Underneath his patch, Leno’s face was visibly bruised.
Comparison of 1 square metre with some Imperial and metric units of area. The square metre (international spelling as used by the International Bureau of Weights and Measures) or square meter (American spelling) is the unit of area in the International System of Units (SI) with symbol m 2. [1]
