0x6f

0x6F is a hexadecimal notation for a byte value. The prefix 0x signals that the digits that follow are in base 16, a common convention in programming and digital electronics.

In base-10 terms, 0x6F equals 6 × 16 + 15, which is 111. In binary, this value is 01101111. This compact representation is frequently used in low-level programming, memory dumps, and data serialization to express byte values or bit patterns.

Character mapping links 0x6F to the Latin small letter o. In ASCII and Unicode, the code point for the lowercase o is U+006F, and the byte value 0x6F corresponds to that character in ASCII-compatible encodings. In UTF-8, the same byte 0x6F represents the character o when encoded as a single-byte ASCII-compatible character.

Common uses include writing hex literals in source code (for example, in C, C++, JavaScript), representing byte values in data streams, and encoding in URLs as percent-encoding (%6F for the character o). It also appears in hex dumps and debugging outputs to display raw byte values.
