Fathoms I think.
There area many units used for measurement of the distances .But , the S.I unit od distance is meters ( m ) .
Meters and Kilometers
We measure length in one direction using standard units. Whether it's feet, meters or light years, it's 1-dimensional. Area is a 2-dimentional concept. It's the distance in one direction and the distance in another direction. Distance times distance is the units times the units, or units squared (units2). We see square centimeters, square feet, or square kilometers as well as other units used to measure this 2-dimentional characteristic. Volume is defined as the amount of space something takes up. Space is a 3-dimensional concept, so a 3-dimensional units are required. You've already guessed that's where cubic inches, cubic centimeters or cubic kilometers (units3) is used to measure this 3-dimentional characteristic.
200 ^2 = 40000 You should be able to do the remaining. Note: distance cannot be used to measure area Area = distance ^2 (units wise)
For example, on a number line (which is one dimensional object), we measure the distance of two points in units. For example, the distance between 2 and 4 is 2 units. Any nth side of a polygon, can be measured by using linear units, such as cm, in., ft, km, etc. The circumference of a circle, the length of an arc, also are measured by linear units. A unit that is used to measure the distance between two points, is called linear dimension.

Lightyears and miles
light years
Meters and Kilometers
It depends on what it of distance is being used. A million million kilometres is 6684 astronomical units, which is the distance travelled by light in 3.3 million seconds, or 5½ weeks.
Light year or astronomical units
nautical mile
For measuring length/distance, meter is used. Other units are km / cm/ mm.
There are two main units of distance used for measuring space distances, they are solar units and light years
In olden days, they were used for measuring mass, distance and volumes. Nowadays, these units are not used in science anywhere in the world except in the US.
The official (international) unit for energy is the joule. Other units frequently used include the calorie, the electron-volt. In general, by the definition of work (which is basically energy) as force x distance, any product of units of force and distance can also be used, for example the foot-pound.
