81AE hexadecimal to binary

Here we will show you how to convert the hexadecimal number 81AE 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 81AE from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 81AE by 16⁰, multiply the second to last digit in 81AE by 16¹, multiply the third to last digit in 81AE by 16², multiply the fourth to last digit in 81AE by 16³, and so on, until all the digits are used.

E × 16⁰ = 14
A × 16¹ = 160
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:

14 + 160 + 256 + 32768 = 33198

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.

33198 ÷ 2 = 16599 with 0 remainder
16599 ÷ 2 = 8299 with 1 remainder
8299 ÷ 2 = 4149 with 1 remainder
4149 ÷ 2 = 2074 with 1 remainder
2074 ÷ 2 = 1037 with 0 remainder
1037 ÷ 2 = 518 with 1 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 81AE hexadecimal to binary:

81AE hexadecimal = 1000000110101110 binary
