Example: convert 15 as to None:
15 as = 15 × 2.78538308834547e-22 None = 4.17807463251821e-21 None
Attosecond to Hour (Sidereal) Conversion Table
| attosecond | hour (sidereal) |

Attosecond
An attosecond is a unit of time equal to 10^-18 seconds, used to measure extremely short durations, particularly in atomic and subatomic processes.
History/Origin
The attosecond was introduced in the early 21st century as scientists developed ultrafast laser techniques to observe electron dynamics, marking a significant advancement in time measurement at atomic scales.
Current Use
Attoseconds are primarily used in physics and chemistry to study ultrafast phenomena such as electron movements, chemical reactions, and quantum dynamics, often through attosecond laser pulses and spectroscopy.
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.
