About this tool
Type a number like 2026 to get MMXXVI, or a Roman numeral like MCMXCIV to get 1994. Valid numerals are checked, so a wrong form such as IIII is flagged. Useful for dates on buildings, chapters, clocks and tattoos.
When to use it
Convert numbers to Roman numerals and back.
Tips
Roman numerals do not have zero. They cover 1 to 3,999 in standard form.
Privacy
Everything runs in your browser, so your data is not uploaded or stored.
Rules
I is 1, V is 5, X is 10, L is 50, C is 100, D is 500 and M is 1,000. A smaller symbol before a larger one subtracts, so IX is 9 and XL is 40.
計算示例
With the boxes at their starting values (Number or Roman numeral: 2026), the tool shows: Number: 2026; Roman numeral: MMXXVI. Change any box to see your own numbers. The result updates as you type, and nothing leaves your browser.
