100 femtoseconds
Time: 100 fs; definition.
Time conversions use a Julian year of exactly 365.25 days.
Atomic-scale transition
Time: 1 fs; reference interval.
A chosen femtosecond process interval; real transitions span many timescales.
Defined examples — our methodology
The marked time is calibrated. Unmeasured illustration details are representative.

How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- The duration of an atomic-scale transition: The measurement is labelled reference interval. Check the source notes for its basis.
