API, OpenAPI and WebMCP documentation

Explanation

The converter converts Roman libra into Kilograms using one fixed ancient-mass reference model. Formula: Kilograms = Roman libra × 0.32745.

Ancient mass and weight units varied across periods and regions, so this page keeps one canonical scholarly approximation for modern reference instead of implying one universal historical standard.

Historical reference: this is a fixed modern approximation. A specific period, locality and primary measurement source have not been established for every unit in this dataset. Check those details before applying it to an artifact or historical record.
