0XFFF to decimal 0XFFF is a hexadecimal (hex) number. We can tell it is a hex number because it starts with 0X. Hexadecimal numbers like 0XFFF are not often used in daily life, but we see them used for certain things such as html colors, shortening binary numbers, computer error codes, and math exercises.

The hexadecimal number system has 16 symbols (base 16) instead of the decimal system which has 10 numbers (base 10). The hex symbols are 0 1 2 3 4 5 6 7 8 9 A B C D E F where A=10, B=11, C=12. D=13, E=14, and F=15.

Like we said above, the 0X indicates that it is a hex number and that is the only purpose of 0X. Thus, to convert a hex number such as 0XFFF to decimal, we only need to look at the symbols after 0X which are FFF.

To convert the hex number 0XFFF to decimal (or any other hexadecimal number for that matter), you follow these steps:

Step 1) Multiply the last digit by 1, Multiply the second to last digit by 16, Multiply the third to the last digit by 16 x 16, Multiply the fourth to the last digit by 16 x 16 x 16, Multiply the fifth to the last digit by 16 x 16 x 16 x 16 and so on until all the digits are used.

Step 2) Add up all the products you got from Step 1 to get the answer to 0XFFF in decimal.

Here is the math using using the steps above showing you how to convert 0XFFF to decimal.

F x 1 = 15
F x 16 = 240
F x 16 x 16 = 3840

15 + 240 + 3840 = 4095

That is all there is to it. Here is the answer to 0XFFF in decimal:
