4C81 hexadecimal to binary

Here we will show you how to convert the hexadecimal number 4C81 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 4C81 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 4C81 by 16⁰, multiply the second to last digit in 4C81 by 16¹, multiply the third to last digit in 4C81 by 16², multiply the fourth to last digit in 4C81 by 16³, and so on, until all the digits are used.

1 × 16⁰ = 1
8 × 16¹ = 128
C × 16² = 3072
4 × 16³ = 16384

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 + 3072 + 16384 = 19585

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.

19585 ÷ 2 = 9792 with 1 remainder
9792 ÷ 2 = 4896 with 0 remainder
4896 ÷ 2 = 2448 with 0 remainder
2448 ÷ 2 = 1224 with 0 remainder
1224 ÷ 2 = 612 with 0 remainder
612 ÷ 2 = 306 with 0 remainder
306 ÷ 2 = 153 with 0 remainder
153 ÷ 2 = 76 with 1 remainder
76 ÷ 2 = 38 with 0 remainder
38 ÷ 2 = 19 with 0 remainder
19 ÷ 2 = 9 with 1 remainder
9 ÷ 2 = 4 with 1 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 4C81 hexadecimal to binary:

4C81 hexadecimal = 100110010000001 binary
