81F0 hexadecimal to binary

Here we will show you how to convert the hexadecimal number 81F0 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 81F0 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 81F0 by 16⁰, multiply the second to last digit in 81F0 by 16¹, multiply the third to last digit in 81F0 by 16², multiply the fourth to last digit in 81F0 by 16³, and so on, until all the digits are used.

0 × 16⁰ = 0
F × 16¹ = 240
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:

0 + 240 + 256 + 32768 = 33264

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.

33264 ÷ 2 = 16632 with 0 remainder
16632 ÷ 2 = 8316 with 0 remainder
8316 ÷ 2 = 4158 with 0 remainder
4158 ÷ 2 = 2079 with 0 remainder
2079 ÷ 2 = 1039 with 1 remainder
1039 ÷ 2 = 519 with 1 remainder
519 ÷ 2 = 259 with 1 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 81F0 hexadecimal to binary:

81F0 hexadecimal = 1000000111110000 binary
