Convert FFF Hex to Decimal

Here we will show you how to convert FFF Hex to Decimal and then give you the answer.

Step 1) Count the digits in FFF, which in this case is 3 digits, and convert each digit to Hex if necessary per Table 1.

Step 2) Starting from the last number in Step 1, multiply the first number with 1, the second number with 16, and the third number with 256. (See Table 2 for details.)

Step 3) Add up all the numbers you got in Step 2 to get the answer.

Following the instructions above, your math should look like this:

15 x 1 = 15
15 x 16 = 240
15 x 256 = 3840

15 + 240 + 3840 = 4095

Thus, we got the following answer:

FFF = 4095
