A little perspective
100 femtoseconds lasts about 100 times as long as Atomic-scale transition.

100 femtoseconds
Time conversions use a Julian year of exactly 365.25 days.
Atomic-scale transition
A chosen femtosecond process interval; real transitions span many timescales.
Defined examples — our methodology
The marked time is calibrated. Unmeasured illustration details are representative.
Measurement details
Why these numbers?
The visual compares time with time. The records below preserve each value’s basis and caveats.
Atomic-scale transition
1 fsTime · reference interval
A chosen femtosecond process interval; real transitions span many timescales.
- Comparing
- Time ↔ Time
- Relative size
- 100 femtoseconds is larger on this measurement by a factor of about 100.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Atomic-scale transition is labelled reference interval; treat the displayed value as a comparison anchor rather than false precision.
