    Supported unit conversions

This online metric to imperial unit converter supports conversions from nanometers (nm), micrometers (μm), millimeters (mm), centimeters (cm), decimeters (dm), meters (m), and kilometers (km) to inches (in), feet (ft), yards (yd), miles (mi), nautical miles (M), and leagues (lea). It uses the standards defines by the International System of Units and ISO standards on quantitities and units [1][2]. The league is the only exception as it does not have an official standard.

    Metric vs. Imperial units of length

Metric units are the internationally adopted system of units used in engineering, science, navigation, land measurement, etc. and have the meter as a basis, which is defined as the distance light travels in a vacuum in 1/299,792,458 seconds. The units from the metric system are the official ones in most countries of the world, with the exception of the United States, United Kingdom, and a couple of other countries.

Some imperial units continue to be used in naval and air navigation for historical reasons (the nautical mile), while others have entered through innovation, for example screen/display sizes are usually listed in inches since historically they were designed in countries using the imperial system. From the units supported by our metric to imperial converter, the league is the only one without an official definition, since it is not an official unit of length in any country.

    How to convert metric to imperial units?

Our metric unit converter supports many different pairs of units, so we will give examples on how to perform a unit conversion for only some of the most popular pairs.

Cm to inch conversion example

Sample task: convert 50 cm to inches. Solution:

cm / 2.54 = in
50 cm / 2.54 = 19.685039 in
End result:
50 cm is equal to 19.685039 in

Meters to feet conversion example

Sample task: convert 25 meters to feet. Solution:

m / 0.3048 = ft
25 m / 0.3048 = 82.020997 ft
End result:
25 m is equal to 82.020997 ft

Km to Miles conversion example

Sample task: convert 20 kilometers to miles. Solution:

km / 1.609344 = miles
20 km / 1.6093 = 12.427424 miles
End result:
20 km is equal to 12.427424 miles
