How do I convert binary to hex?
Group binary digits into sets of 4 from the right (pad with zeros if needed). Convert each group: 0000=0, 0001=1... 1010=A, 1111=F.
Why do programmers prefer hex over binary?
Hex is 4 times shorter and far easier to read. The 32-bit value 11111111000000001111111100000000 is just FF00FF00 in hex, and byte boundaries line up with pairs of hex digits.
What if my binary number isn't a multiple of 4 bits?
Pad it with leading zeros until it is. For example, 110 becomes 0110, which is hex 6. Padding on the left never changes the value.
