FAQ
Frequently Asked Questions
How do you convert binary to hexadecimal?
Group the binary digits into sets of 4 starting from the right (pad with leading zeros if needed). Then convert each 4-bit group to its hexadecimal equivalent: 0000=0, 0001=1, ..., 1001=9, 1010=A, 1011=B, 1100=C, 1101=D, 1110=E, 1111=F. Example: 11010110₂ → 1101 0110 → D6₁₆.
Why is binary to hex conversion so simple?
Hexadecimal is base 16, and 16 = 2⁴. This means exactly 4 binary digits map to 1 hex digit. This direct power-of-2 relationship makes the conversion a simple substitution — no arithmetic is needed, just group and replace.
What are hexadecimal digits?
Hexadecimal uses 16 symbols: 0-9 for values 0-9, and A-F for values 10-15. A=10, B=11, C=12, D=13, E=14, F=15. Hex is case-insensitive, so 'a' and 'A' both represent 10.
Why is hexadecimal used in programming?
Hexadecimal is used because it provides a compact representation of binary data. One hex digit replaces 4 binary digits, making long binary values much shorter and more readable. It's commonly used for memory addresses, color codes (e.g., #FF5733), MAC addresses, and debugging binary data.
What is a nibble in binary?
A nibble (or nybble) is a group of exactly 4 binary bits. It can represent 16 values (0-15), which maps perfectly to one hexadecimal digit. Two nibbles make one byte (8 bits). The term comes from being 'half a byte.'
How do you convert hex back to binary?
Replace each hex digit with its 4-bit binary equivalent: 0→0000, 1→0001, ..., 9→1001, A→1010, B→1011, C→1100, D→1101, E→1110, F→1111. Example: 3F₁₆ → 0011 1111₂. This is the exact reverse of binary-to-hex conversion.
