C90F hexadecimal to binary

Here we will show you how to convert the hexadecimal number C90F 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 C90F from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in C90F by 16⁰, multiply the second to last digit in C90F by 16¹, multiply the third to last digit in C90F by 16², multiply the fourth to last digit in C90F by 16³, and so on, until all the digits are used.

F × 16⁰ = 15
0 × 16¹ = 0
9 × 16² = 2304
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:

15 + 0 + 2304 + 49152 = 51471

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.

51471 ÷ 2 = 25735 with 1 remainder
25735 ÷ 2 = 12867 with 1 remainder
12867 ÷ 2 = 6433 with 1 remainder
6433 ÷ 2 = 3216 with 1 remainder
3216 ÷ 2 = 1608 with 0 remainder
1608 ÷ 2 = 804 with 0 remainder
804 ÷ 2 = 402 with 0 remainder
402 ÷ 2 = 201 with 0 remainder
201 ÷ 2 = 100 with 1 remainder
100 ÷ 2 = 50 with 0 remainder
50 ÷ 2 = 25 with 0 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 C90F hexadecimal to binary:

C90F hexadecimal = 1100100100001111 binary
