How convert decimal to hexadecimal?

Answer 1

The places in base 10 (decimal) increase by powers of 10. The places in base 16 (hexadecimal) increase by powers of 16.

16^0 = 1

16^1 = 16

16^2 = 256

16^3 = 4096

Since you can have up to 15 units in a place before moving up to the next place the letters A through F are used to extend the numbers 0-9

Let's take a random number like 1107 base 10.

There are four 256's in 1107, leaving 83. There are five 16's in 83, leaving 3. There are three ones in 3.

1107 base 10 = 453 base 16
