Kilosecond

Kilosecond

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).

Usage

*It took me two kiloseconds to get to work today (about half an hour)
*The meeting was about 4 kiloseconds long (just over an hour)
*The snail crossed the desk in 1.3 kiloseconds (21.6 minutes)
*The train arrived 1.167 kiloseconds late (19.45 minutes)

Orders of Magnitude

To help compare orders of magnitude of different times, this page lists times between 103 seconds and 104 seconds (approximately 16.7 minutes to 2.8 hours). A kilosecond is one thousand seconds.
