Translate values between decimal, binary, hexadecimal, octal, and related bases for programming and digital electronics.
Binary allows 0–1, octal 0–7, decimal 0–9, and hexadecimal 0–9 plus A–F. Invalid characters are rejected or ignored so results stay trustworthy.
Hex compresses binary into readable pairs (one hex digit = four bits), which is ideal for memory addresses, color channels, and byte dumps.
It focuses on base conversion of integer values. For percentages, interest, or loan math, use the Finance & Math calculators instead.
