How to convert decimal to hexadecimal
To convert decimal to hexadecimal, type your number in the converter above and read the hexadecimal value. For example, 214 in decimal is D6 in hexadecimal. The other bases are shown at the same time.
Why convert decimal to hexadecimal
Developers convert decimal to hex to write colours (255, 128, 0 is FF8000), set memory offsets, build byte arrays and read register maps. The number 214 becomes D6: two digits instead of three, and a value that lines up neatly with a byte.
Convert decimal to hexadecimal by hand
Here is 214 (decimal) converted step by step:
- Divide the number by 16 repeatedly and note each remainder: 214 ÷ 16 = 13 remainder 6, 13 ÷ 16 = 0 remainder D.
- Stop when the quotient reaches 0.
- Read the remainders from last to first: D6.

Check your answer
To check the result, convert it back: D6 in hexadecimal is 214 in decimal. Your input may only contain the decimal digits 0 1 2 3 4 5 6 7 8 9; any other character is not a valid decimal number.
Good to know
- Divide by 16: the last remainder is the first digit of the result.
- Values from 0 to 255 always fit in two hex digits.
- Hex digits above 9 are letters: 10 is A, 11 is B and so on up to 15, which is F.
- The converter also shows the other bases at the same time, so a single entry gives you binary, decimal, hexadecimal and octal.
