Kilosecond
From Wikipedia, the free encyclopedia
A kilosecond is 1000 seconds (16 minutes, 40 seconds), so there are 86.4 kiloseconds in a 24 hour day. 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 use of kiloseconds (1000 seconds) in research papers is increasing in popularity, but is still far less common than the standard hour (3600 seconds).
