The term "klick" is derived from the word "kilometer." So, one klick equals one kilometer. If a soldier radios "We're 10 klicks south of your position," that means they are 10 kilometers away, or 6.2 miles away.

The British eventually used the Roman mile as a model in their measurement system, but they didn't want to give up their furlong. The Roman mile was about seven-and-one-half furlongs, and when the British adopted it, they lengthened the Roman mile to eight furlongs, which equals 5,280 feet.
It originated from the Roman mille passus, or “thousand paces,” which measured 5,000 Roman feet. About the year 1500 the “old London” mile was defined as eight furlongs. At that time the furlong, measured by a larger northern (German) foot, was 625 feet, and thus the mile equaled 5,000 feet.
According to this, one knot was defined as one nautical mile and one nautical mile represented 6,080 feet (1853.18 meters).
sm (or NM) 1,852 km. 0,54 sm. 1 statute mile = 1760 Yards = 5280 feet.
The word mile stems from the Latin word mille, which means 1,000. In an act of Parliament, Queen Elizabeth I decreed that a mile was to be eight furlongs, 80 chains, 320 rods [1], 1,760 yards or 5,280 feet. The length was statutorily decided upon in 1592, hence the name statute mile.
SM = Statute Miles, which is like a regular mile that most people use in their daily lives. It's depicted as SM, due to most other things in aviation being in Nautical Miles.
"Statute" gives distance in miles, elevation in feet, temperature in Fahrenheit. "Metric" gives distance in km, elevation in metres, temperature in Celsius.
A nautical mile is a unit of measurement used in air, marine, and space navigation, and for the definition of territorial waters. Today the international nautical mile is defined as exactly 1852 metres (6076 ft; 1.151 mi). The derived unit of speed is the knot, one nautical mile per hour.
Video shows what statute mile means. A standard land mile of 5,280 feet or 1,760 yards or 1.609344 kilometers.
Miles And MilesThe familiar land mile is 5,280 feet, is called a statute mile, and it's based on paces. On the other hand, the nautical mile is used for distances on the ocean and doesn't have a tangible equivalent like paces. In navigation, one minute is called a nautical mile.
Identify and label the nm. We have changed our scale again, and now each one thousandth of our scaled up micrometer is equal to one nanometer (nm). One nanometer is about 10 atoms lined up, diameter to diameter, it is also how much your fingernails grow in one second.
Nanometer (nm), an SI unit of length, equal to 10−9 m (a thousand-millionth of a meter) Nanomolar (nM), in chemistry, one thousand-millionth molar. Nautical mile (NM or nmi), a unit of length used for maritime and aviation purposes. Newton metre (Nm, may also be written as N·m), a unit of torque.
Nanometer A nanometer is 1000 times smaller than a micrometer. 1 micrometer (μm) = 1000 nanometers.
A nanometer is one billionth of a meter, also expressed as 0.000000001 or 10-9 meters (for perspective, hair grows at roughly 1 nm per second**). In chip design, “nm” refers to the length of a transistor gate – the smaller the gate the more processing power that can be packed into a given space.
The newton-metre (also newton metre; symbol N⋅m or N m) is a unit of torque (also called moment) in the SI system. One newton-metre is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long. The nonstandard notation Nm occurs in some fields.
The metre is defined as the length of the path travelled by light in a vacuum in 1299 792 458 of a second. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately 40000 km.
Just how small is “nano?” In the International System of Units, the prefix "nano" means one-billionth, or 10-9; therefore one nanometer is one-billionth of a meter. It's difficult to imagine just how small that is, so here are some examples: A sheet of paper is about 100,000 nanometers thick.
A degree of longitude is widest at the equator with a distance of 69.172 miles (111.321 kilometers). The distance gradually shrinks to zero as they meet at the poles. At 40 degrees north or south, the distance between a degree of longitude is 53 miles (85 kilometers).
The angular measure of degree can be sub divided into smaller parts known as minute, and the relationship that holds is: 1° = 60' = 60 minutes. Another thing that can be derived from this is: 1° = 60 minutes = 4 minutes.
Because, just like in sailing on the open ocean, when you are traveling a long distance you want to use a unit of length that is directly related to latitude and longitude. The nautical mile is one minute of latitude. Knowing your latitude you also know the factor to determine what one minute of longitude is.
Divide the amount of miles by the degrees in a circle. The circumference of the earth along the equator is 24,901.92 miles, and there are 360 degrees in a circle. This results in about 69.2 miles. That is the approximate distance between each degree of latitude.
