Convert hour (sidereal) to millisecond

Please provide values below to convert hour (sidereal) [None] to millisecond [ms], or Convert millisecond to hour (sidereal).

1 None = 3590170.43 ms. To convert hour (sidereal) to millisecond, multiply the value by 3590170.43; to go the other way, divide by it (1 ms = 2.78538308835e-07 None). Both units measure time and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

  • 1 None = 3590170.43 ms

Hour (Sidereal)

An hour (sidereal) is a unit of time based on the Earth's rotation relative to distant stars, equal to approximately 3,894 seconds, used primarily in astronomy.

History/Origin

The sidereal hour originated from the ancient division of the day based on Earth's rotation relative to the stars, differing from the solar hour by about 4 minutes, and has been used historically in astronomy for precise timekeeping.

Current Use

Sidereal hours are mainly used in astronomy and astrophysics to measure celestial events and the Earth's rotation relative to distant celestial objects, rather than in everyday timekeeping.


Millisecond

A millisecond (ms) is a unit of time equal to one thousandth of a second.

History/Origin

The millisecond was introduced as a standard unit of time measurement with the development of precise timekeeping and scientific instrumentation in the 20th century, particularly with the advent of electronic clocks and digital technology.

Current Use

Milliseconds are widely used in computing, telecommunications, and scientific measurements to denote very short durations, such as in data processing, network latency, and high-frequency trading.
