AC91 hexadecimal to binary

Here we will show you how to convert the hexadecimal number AC91 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 AC91 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in AC91 by 16⁰, multiply the second to last digit in AC91 by 16¹, multiply the third to last digit in AC91 by 16², multiply the fourth to last digit in AC91 by 16³, and so on, until all the digits are used.

1 × 16⁰ = 1
9 × 16¹ = 144
C × 16² = 3072
A × 16³ = 40960

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:

1 + 144 + 3072 + 40960 = 44177

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.

44177 ÷ 2 = 22088 with 1 remainder
22088 ÷ 2 = 11044 with 0 remainder
11044 ÷ 2 = 5522 with 0 remainder
5522 ÷ 2 = 2761 with 0 remainder
2761 ÷ 2 = 1380 with 1 remainder
1380 ÷ 2 = 690 with 0 remainder
690 ÷ 2 = 345 with 0 remainder
345 ÷ 2 = 172 with 1 remainder
172 ÷ 2 = 86 with 0 remainder
86 ÷ 2 = 43 with 0 remainder
43 ÷ 2 = 21 with 1 remainder
21 ÷ 2 = 10 with 1 remainder
10 ÷ 2 = 5 with 0 remainder
5 ÷ 2 = 2 with 1 remainder
2 ÷ 2 = 1 with 0 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 AC91 hexadecimal to binary:

AC91 hexadecimal = 1010110010010001 binary
