Metron is a dnd5e-specific module converting actors, items, their descriptions and text fields, as well as scenes and journal entries from imperial to metric units.
IMPORTANT: While the module aims to reliably convert documents in place, it is heavily recommended to make a backup of all data to be converted.
To convert a document, click on the Convert button in the document's sheet's header buttons.
This will convert that particular document, as well as all documents embedded in it (e.g. Items in an Actor) to the unit system selected in the module's settings.
Converting in the reverse direction is possible by Shift-Clicking the Convert button.
Scenes and compendiums have their Convert button in their right-click menu.
The used conversion rates do not strictly follow real word ones, but adhere to the simplified rules, e.g. 5 feet are converted to 1.5 meters.
By default, Metron always converts units written in English (e.g. 5 ft, or 2 miles).
Additional languages are added dependent on the currently active language of FoundryVTT.
- English (always active)
- Japanese
