→Method 4: Hexadecimal to Binary / Binary to Hexadecimal
# One hexadecimal number represents 4 binary numbers, so starting from right-side, group binary digits into groups of 4 (add leading zeros if necessary).
# Write (8)(4)(2)(1) under <u>each</u> group of 3 binary numbers.
# Multiply the placeholders (i.e. 0's and 1's) by the corresponding (8)(4)(2)(1) for each group to obtain the octal number.
# Convert values from 10 to 15 to A to F (refer to diagram of ''binary to hexadecimal'' conversion)<br><br>
