For people & software
Conversion Encyclopedia
Unit conversion tools and API for people, developers and AI agents
Conversion Encyclopedia combines readable calculators and reference pages with a machine-readable API. Convert everyday units, ingredients, materials and technical measurements through one consistent, documented engine.
- Human-readable toolsCalculators, reference tables and clearly stated assumptions.
- Context-aware resultsExact unit math plus density, ingredient and technical profiles where required.
- Agent-ready accessJSON API, OpenAPI, API Catalog and WebMCP on the same conversion engine.
Scope & Verification
Use category hubs to open exact conversion families, then move into leaf pages that keep one explicit basis per route.
- Category hubs separate exact-factor, profile-based, density-based, and estimate-based systems.
- Leaf pages surface calculators, common-value tables, reverse routes, and source notes when available.
- Methodology and verification pages explain how fixed factors and assumptions are kept aligned.
Explanation
Conversion Encyclopedia is a measurement reference for both people and software. Human-readable pages provide calculators, common-value tables, explanations and explicit assumptions. Developers and compatible AI agents can request the same conversion logic through the JSON API, discover operations through OpenAPI and API Catalog, or use browser-exposed WebMCP tools.
The encyclopedia is organized by measurement context so different rule sets do not collapse into one generic answer. Cooking and beverage pages separate ingredient or liquid density from universal unit math, while technical hubs keep exact SI, metric, imperial, nautical, or scientific reference definitions explicit on each route.
Start from the family that matches your task, then open the exact page for the unit direction and item you need. Hubs summarize scope, assumptions and verification, while leaf pages expose the same basis across the snapshot, calculator, common values, FAQ and reverse page. The public machine interfaces reuse that canonical engine rather than maintaining a separate set of answers.
Questions & answers
Frequently Asked Questions
What is a conversion encyclopedia?
It is organized as families, hubs, and leaf pages so you can navigate from a domain to a specific conversion. Leaf pages show the factor used for each calculation.
How are converter families organized?
Families group pages by unit pairing and measurement rules, and each family has a hub listing available leaf pages. Cooking and Beverage grams↔volume families use ingredient-specific density, while other families use universal factors.
What makes a converter page “verified”?
Verified means the numeric factor was reviewed against source data and approved for publication. Verified leaf pages show the exact factor used.
How should I navigate the site?
Start with a family hub, then open the leaf page for your exact unit direction and item if needed. Choose an ingredient when converting grams↔volume in Cooking or Beverage.
Can developers and AI agents use the conversion engine?
Yes. The public JSON API uses the same canonical conversion engine as the website, with machine-readable discovery through OpenAPI, API Catalog and WebMCP. Usage details and examples are available in the developer documentation.
