About Fathom (ftm)

Traditionally equal to 6 feet (1.8288 meters), the fathom originated as the span of a sailor's outstretched arms and has been used for centuries to measure water depth. Nautical charts and depth soundings still reference fathoms in many maritime traditions, and Mark Twain's pen name came from the riverboat call 'mark twain' meaning two fathoms.

About Light-year (ly)

The distance light travels in one Julian year -- approximately 9.461 trillion kilometers -- the light-year is the standard unit for expressing interstellar distances. Proxima Centauri, the nearest star beyond the Sun, lies about 4.24 light-years away. Despite its name, the light-year measures distance, not time.
