HEX HeroHow to convert Hexadecimal to Binary
Hexadecimal system is probably more familiar as a numeral system that is also commonly used by computers and other digital systems. It is base 16 and it has 16 symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and A, B, C, D, E, F.
Binary system uses only 2 symbols, which are typically expressed as 0 (zero) and 1 (one). It has a positional notation and each digit is referred to as a single bit. All this makes it perfect for digital electronic circuitry and logic gates which means that binary system is used by almost all modern computers and similar devices.
Table #1: Hexadecimal to Binary conversion table
| Hexadecimal | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | A | B | C | D | E | F |
| Binary | 0000 | 0001 | 0010 | 0011 | 0100 | 0101 | 0110 | 0111 | 1000 | 1001 | 1010 | 1011 | 1100 | 1101 | 1110 | 1111 |
Instructions:
- Start with any hexadecimal number
- Represent each hexadecimal digit with the equivalent group of 4 binary digits (see conversion table above)
- Concatenate the resulting binary digits into a single number
- Discard any insignificant leading zeros at the left of the resulting binary number
