B681 hexadecimal to binary

Here we will show you how to convert the hexadecimal number B681 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 B681 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in B681 by 16⁰, multiply the second to last digit in B681 by 16¹, multiply the third to last digit in B681 by 16², multiply the fourth to last digit in B681 by 16³, and so on, until all the digits are used.

1 × 16⁰ = 1
8 × 16¹ = 128
6 × 16² = 1536
B × 16³ = 45056

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 + 1536 + 45056 = 46721

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.

46721 ÷ 2 = 23360 with 1 remainder
23360 ÷ 2 = 11680 with 0 remainder
11680 ÷ 2 = 5840 with 0 remainder
5840 ÷ 2 = 2920 with 0 remainder
2920 ÷ 2 = 1460 with 0 remainder
1460 ÷ 2 = 730 with 0 remainder
730 ÷ 2 = 365 with 0 remainder
365 ÷ 2 = 182 with 1 remainder
182 ÷ 2 = 91 with 0 remainder
91 ÷ 2 = 45 with 1 remainder
45 ÷ 2 = 22 with 1 remainder
22 ÷ 2 = 11 with 0 remainder
11 ÷ 2 = 5 with 1 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 B681 hexadecimal to binary:

B681 hexadecimal = 1011011010000001 binary
