A Homepage Is a Map, Not a Landing Page
The homepage now directs visitors from six converters to a preserved pyramid diagram, a rotating unit dossier, focused studies, and the latest build-log entries.

Ancient Measures
Convert and calculate ancient units with academically sourced tools built from primary and scholarly evidence. Move from Classical epics to Tudor records and Roman artefacts across length, weight, time, liquid, area, and treasure; every result keeps its historical basis and limits visible.
