What is 43 in hex?

Answer 1

43 (decimal) converted to hex is: 2B. The 2 is in the sixteen place, so 2 x 16 = 32. The B represents eleven, so 32 + 11 = 43 (decimal).

The method to find from decimal to hex is: divide by 16, take the remainder as the digit, then take the quotient and divide by 16 again and the remainder is the next digit. Keep going until the quotient is zero. So we have 43/16 = 2 remainder 11. So the rightmost digit is B (A is ten, B is eleven, C is twelve, D is thirteen, E is fourteen, F is fifteen). Then take the 2 and divide by 16 = 0 remainder 2, so the next digit is 2.

If instead, you wanted to know what 43 (hex) value converted to decimal is: 4 x 16 = 64, then add 3 = 67 (decimal).
