›› Definition: Mile

A mile is any of several units of distance, or, in physics terminology, of length. Today, one mile is mainly equal to about 1609 m on land and 1852 m at sea and in the air, but see below for the details. The abbreviation for mile is 'mi'. There are more specific definitions of 'mile' such as the metric mile, statute mile, nautical mile, and survey mile. On this site, we assume that if you only specify 'mile' you want the statute mile.


›› Definition: Light-second

A light-second is a unit of length. It is defined as the distance light travels in an absolute vacuum in one second or 299,792,458 meters. Note that this value is considered exact, since the meter is actually (as of 1983) defined in terms of the light second. It is just over 186,282 miles and almost 109 feet.
