About ConvertNavi
ConvertNavi is the global unit conversion hub: instant converters, exact formulas, downloadable reference tables, cooking conversions with ingredient density, fuel economy, data units, plus a free API and embeddable widgets.
Principles
- • Exact when defined. NIST SP 811 and BIPM SI brochure exact factors are used wherever international agreement exists.
- • Approximate when honest. Cooking, density-dependent and ambient-condition values are clearly labelled approximate.
- • One URL per intent. A pair page is the canonical for that conversion intent; widget URLs are noindex.
- • No tracking gymnastics. No login, no email capture, no popups.
- • Open data, open API. Every conversion the website does is reachable through the JSON API.

- • USDA FoodData Central (cooking densities)
- • IEC 80000-13 (binary vs decimal prefixes for data)
