Braille Numbers Converter

In short Braille has no separate digits. The numbers 1 to 9 and 0 reuse the cells for the letters a to i and j, and a number sign — dots 3-4-5-6 — is written in front to say that digits are meant. So 2026 is five cells: the number sign, then the cells for b, j, b and f. The mistake almost everyone makes writing braille numbers by hand is repeating the number sign before every digit. It is written once per run and stays in force until a space or a letter sign, so a four-digit year takes one sign, not four. The rule has a consequence worth understanding, because it is the reason braille needs a letter sign at all. If a letter from a to j comes straight after a number, there is nothing to distinguish it from another digit, so a letter sign (dots 5-6) is written to cancel the number. That is why "1a" is four cells: the number sign, the digit, the letter sign, then the letter. Letters from k to z need no such warning, because their cells are not digits. It also means braille copied without its number sign is genuinely ambiguous: the cells for "abc" and "123" are identical, and nothing in the text recovers which was intended. If a number you have converted reads back as letters, a missing number sign is the first thing to check.
