CEF9 hexadecimal to binary

Here we will show you how to convert the hexadecimal number CEF9 to a binary number. First note that the hexadecimal number system has sixteen different digits (0 1 2 3 4 5 6 7 8 9 A B C D E F) and the binary number system has only two different digits (0 and 1).

The four steps used to convert CEF9 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in CEF9 by 16⁰, multiply the second to last digit in CEF9 by 16¹, multiply the third to last digit in CEF9 by 16², multiply the fourth to last digit in CEF9 by 16³, and so on, until all the digits are used.

9 × 16⁰ = 9
F × 16¹ = 240
E × 16² = 3584
C × 16³ = 49152

Remember that the hexadecimal number system has sixteen different digits, so when doing the above calculation, we use the following values if applicable: A=10, B=11, C=12, D=13, E=14, and F=15.

Step 2)
Next, we add up all the products we got from Step 1, like this:

9 + 240 + 3584 + 49152 = 52985

Step 3)
Now we divide the sum from Step 2 by 2. Put the remainder aside. Then divide the whole part by 2 again, and put the remainder aside again. Keep doing this until the whole part is 0.

52985 ÷ 2 = 26492 with 1 remainder
26492 ÷ 2 = 13246 with 0 remainder
13246 ÷ 2 = 6623 with 0 remainder
6623 ÷ 2 = 3311 with 1 remainder
3311 ÷ 2 = 1655 with 1 remainder
1655 ÷ 2 = 827 with 1 remainder
827 ÷ 2 = 413 with 1 remainder
413 ÷ 2 = 206 with 1 remainder
206 ÷ 2 = 103 with 0 remainder
103 ÷ 2 = 51 with 1 remainder
51 ÷ 2 = 25 with 1 remainder
25 ÷ 2 = 12 with 1 remainder
12 ÷ 2 = 6 with 0 remainder
6 ÷ 2 = 3 with 0 remainder
3 ÷ 2 = 1 with 1 remainder
1 ÷ 2 = 0 with 1 remainder

Step 4)
In the final step, we take the remainders from Step 3 and put them together in reverse order to get our answer to CEF9 hexadecimal to binary:

CEF9 hexadecimal = 1100111011111001 binary
