Kilosecond

For a list of half-lives in this timescale, see: List of isotopes by half-life

A kilosecond (symbol: ks) is 1000 seconds (16 minutes, 40 seconds), so there are 86.4 kiloseconds in a 24 hour day, and 604.8 kiloseconds in a week. The second is the International System of Units (SI) base unit of time, combine with the prefix kilo- which means 1000, results in the definition of a kilosecond. Although the metric system dictates the use of the kilosecond, it is rarely used in practice. The more common (and irregular) units of minutes (60 seconds) and hours (60 minutes) result in a conversion factor of 3600 when converting seconds to hours. The term kilosecond is most commonly found in astrophysics research articles.

A kilosecond is the longest observation of anti-atom confinement as of 14 April 2011 (2011 -04-14) [1]
