What is an attosecond?

An attosecond is a unit of time equal to one quintillionth of a second (10^-18 seconds), used mainly in ultrafast science to describe very fast processes such as electron dynamics.

Why convert attoseconds to years?

Converting attoseconds to years helps contextualize extremely brief events within much longer timescales, making it easier to compare atomic-scale events to everyday or astronomical durations.

What defines a year in this conversion?

The year used here is based on the Julian year, defined exactly as 365.25 days or 31,557,600 seconds, commonly used in scientific and astronomical contexts.
