Text to Decimal Converter

About this calculator

Every character a computer displays is internally stored as a number — its Unicode code point — and this converter maps each character in your text to that number’s decimal value, so the word “Hi” becomes “72 105” (72 for “H”, 105 for “i”), with each code point separated by a space. This is the same underlying numbering used by Unicode’s more familiar hexadecimal notation (U+0048 for “H”), just expressed in base 10 instead of base 16.

Programmers reach for this kind of conversion when debugging character-encoding issues, working with low-level string or byte representations, or teaching how text is actually represented in memory — since ASCII and Unicode assign every letter, digit, punctuation mark, and emoji a specific numeric identity long before it’s rendered as a glyph on screen. The conversion works in both directions: paste text to get its decimal code points, or paste space-separated decimal numbers to reconstruct the original text.
