Chinese Number Converter

📖 Tool Introduction

Convert between Arabic digits and Chinese numerals, with a third mode that produces the formal money form used on receipts and contracts, including large units such as ten thousand and a hundred million.

Chinese numerals have a few rules that catch people out, and they are worth knowing before trusting any conversion. The first is how zeros work: a run of zeros in the middle is read as a single zero, and zeros at the end are not read at all, so 10005 comes out as one ten thousand zero five rather than a long string of zeros. The second is that ten thousand and a hundred million are grouping units, with the number split into groups of four digits, and whether a zero has to be inserted depends on where a group boundary falls. The third is that the one before ten can be dropped at the start of a number, so ten is read as ten rather than one ten, while the same one inside a larger number is spoken.

The money form uses a different set of characters altogether, the formal ones used on financial documents, paired with units for tens, hundreds and thousands and with markers for yuan, jiao, fen and the word that marks an exact amount. This is a requirement rather than a decoration: a receipt or contract written with the ordinary characters instead of the formal ones can be rejected, which is why it is offered here as a separate direction rather than being folded into the general conversion.

Reading Chinese back into digits works by accumulating against the units. Tens, hundreds and thousands multiply the current figure, while ten thousand and a hundred million promote everything accumulated so far, so a high unit arriving late in the string scales the whole of what came before it. Everyday spellings are recognised too, including the colloquial form of two that turns up in speech.
