Click a bit to toggle it. Bits are numbered from zero on the right.
Read hex four bits at a time.
Start at the right. Split the binary number into groups of four, then replace each group with its hex digit.

AC₁₆ = 10 × 16 + 12 = 172₁₀4 bits = 1 nibble = 1 hex digit. Two nibbles make one byte. That is why a byte always fits in two hex digits.
