Romanumerals is a free site for converting, reading and practising Roman numerals: converters for numbers, dates and years, a validator, charts, centuries, a quiz and guides, in several languages.
Who makes it
The site is made by Gabriel, a developer who also works in digital marketing. He builds the tools and writes the guides and the blog. More about Gabriel
How the content is made
- Conversions are calculated, not typed. Every numeral, breakdown and table on the site comes from the same tested code that runs the converter.
- Facts have sources. When a page says a numeral was used somewhere (a clock, a pope's name, a numbered event), the source is linked next to it.
- AI is only a first draft. AI may be used to draft text, never to supply facts, and every page is reviewed before it is published.
- Each language is written for its readers. Spanish pages follow Spanish conventions for centuries, Italian pages Italian ones, and so on.
The guides explain the system in depth, starting with how Roman numerals work.
