How Decimal Converts to Hexadecimal

Hexadecimal is base 16, using digits 0-9 plus letters a-f to represent the values 10-15 in a single digit. The standard conversion method is repeated division by 16: divide by 16, keep the remainder as a hex digit, divide the quotient by 16 again, and repeat until the quotient is 0. The hex result is the remainders read from last to first.

How to Convert Decimal to Hexadecimal

Converting 255: 255 ÷ 16 = 15 remainder 15 (which is 'f'), 15 ÷ 16 = 0 remainder 15 (also 'f'). Reading the remainders in reverse order: ff. Converting 202: 202 ÷ 16 = 12 remainder 10 (which is 'a'), 12 ÷ 16 = 0 remainder 12 ('c'). Reading in reverse: ca.
