FAQ

A: Uppercase Chinese numerals output values such as “壹佰贰拾叁”; uppercase RMB amounts add “元, 角, 分, 整” according to currency formatting. For example, 120.50 is converted to “壹佰贰拾元伍角”.

A: Standard Roman numeral conversion supports integers from 1 to 3999 and validates whether common subtractive forms such as IV, IX, XL, and CM comply with the rules.

A: Yes. Base conversion uses big integer processing, making it suitable for long binary, decimal, and hexadecimal numbers while avoiding precision errors caused by regular decimal calculations.

A: In settings, change “Processing Method” to “Batch convert by line,” then enter one value per line. After conversion, the page will preview the first 20 lines, while copy and CSV export will retain all results.

A: Select “Custom Base Conversion” in the “Base Conversion” category, then set the source base and target base. Bases from 2 to 36 are supported, and characters can use 0-9 and A-Z.
