Meters to leagues [nautical] formula

The meter is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second. One metre is about 3 3⁄8 inches longer than a yard, i.e. about 39 3⁄8 inches.

Here are some common conversions from meters to other length units:

1 meter = 100 centimeters
1 meter = 3.28084 feet
1 meter = 1.09361 yards
1 meter = 0.000621371 miles
1 meter = 39.3701 inches

Conversely, to convert from these other units of length to metres, you would use the appropriate conversion factor, either by multiplying or dividing the original quantity by the factor.

In summary, the meter is a unit of length in the SI system and is commonly used to measure distance and length in a variety of contexts. Its basis in units of 10 makes it easy to convert to other units of length.

Here are some examples of things that measure about one meter (order of magnitude):

A typical human arm span
A meter stick or yardstick
A bicycle frame size
A large pizza
A three-foot (1 meter) long fish
A standard kitchen countertop
A medium-sized dog
A basketball hoop height
A typical pool cue length
A standard walking cane
A small ladder or step stool
Microwaves of 300 GHz have a wavelength of 1 mm

An international nautical league is an obsolete unit of length, which was equal to three nautical miles (about 5.6 km).
