8181 hexadecimal to binary

Here we will show you how to convert the hexadecimal number 8181 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 8181 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 8181 by 16⁰, multiply the second to last digit in 8181 by 16¹, multiply the third to last digit in 8181 by 16², multiply the fourth to last digit in 8181 by 16³, and so on, until all the digits are used.

1 × 16⁰ = 1
8 × 16¹ = 128
1 × 16² = 256
8 × 16³ = 32768

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 + 128 + 256 + 32768 = 33153

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.

33153 ÷ 2 = 16576 with 1 remainder
16576 ÷ 2 = 8288 with 0 remainder
8288 ÷ 2 = 4144 with 0 remainder
4144 ÷ 2 = 2072 with 0 remainder
2072 ÷ 2 = 1036 with 0 remainder
1036 ÷ 2 = 518 with 0 remainder
518 ÷ 2 = 259 with 0 remainder
259 ÷ 2 = 129 with 1 remainder
129 ÷ 2 = 64 with 1 remainder
64 ÷ 2 = 32 with 0 remainder
32 ÷ 2 = 16 with 0 remainder
16 ÷ 2 = 8 with 0 remainder
8 ÷ 2 = 4 with 0 remainder
4 ÷ 2 = 2 with 0 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 8181 hexadecimal to binary:

8181 hexadecimal = 1000000110000001 binary
