Tools & Resources
Explore inventories, standards registries, and reference materials designed to make units accessible to humans, machines, and AI systems alike.
A semantic gateway and API to the physical fundamental constants. Built for science, designed for discovery and machine actionability.
A comprehensive digitization project that transforms CODATA fundamental physical constants into machine-actionable and legacy formats, enabling seamless integration with modern data science workflows, AI systems, and agent-based applications.
The SI Reference Point is a digital representation of the SI Brochure, which defines the International System of Units (SI), the world’s internationally agreed system of units. By making core SI reference information available in machine-readable form, the SI Reference Point helps ensure that the SI can be used consistently in digital applications and data exchange. .
The landmark publication 'Stop squandering data: make units of measurement machine-readable' outlining challenges and solutions for digital metrology.
A technical companion and implementation guide outlining standard digital representation patterns and metadata standards to ensure datasets are AI-ready.
A collection of open-source, semantic ontologies and data standards used to represent physical quantities, units of measure, and their mathematical dimensions in software and scientific data
A code system intended to include all units of measures contemporarily used in international science, engineering, and medicine, providing unambiguous electronic representation and conversion.
