Unit Converter: Length (metre, inch, yard)

Convert length units such as Metric system, United States customary units / Imperial units, and Japanese units of measurement to each other.
Round to the 14th decimal place.

* About the notation of "e": Numbers with many digits may be displayed as "1e9". This is a computer exponential notation, where “e” represents a power of 10.

1e3 = 10³ = 1,000

1e6 = 10⁶ = 1,000,000

1e9 = 10⁹ = 1,000,000,000

1e-3 = 10^-3 = 0.001

1e-6 = 10^-6 = 0.000001

1e-9 = 10^-9 = 0.000000001

Length conversion formula

Metric system

1km = 10^3m

1m = 10^2cm = 10^3mm = 10^6μm = 10^9nm = 10^{10}\text{\AA}

United States customary units / Imperial units

1mile = 8furlong = 80chain = 1760yard

1yard = 3foot = 36inch

1inch = 25.4mm

Japanese units of measurement

1\text{里} = 36\text{町}

1\text{町} = 60\text{間} = 360\text{尺}

1\text{間} = 6\text{尺}

1\text{丈} = 10\text{尺}

1\text{尺} = 10\text{寸} = {\dfrac {10}{33}}m \approx 0.3030303m

Nautical

1nm = 1852m
