About this tool
Each hexadecimal digit becomes exactly four binary digits, so conversion is digit by digit. For 2F: 2 is 0010 and F is 1111, which gives 0010 1111.
Leading zeros in the first group do not change the value.
Formula
- Replace each hex digit with its four-bit pattern: 0=0000, 1=0001 … 9=1001, A=1010 … F=1111.
Examples
- Hexadecimal A = 1010 (binary)
- Hexadecimal 2F = 0010 1111 (binary)
- Hexadecimal FF = 1111 1111 (binary)
- Hexadecimal 1A3 = 0001 1010 0011 (binary)
Tips
