A5B1 hexadecimal to binary

Here we will show you how to convert the hexadecimal number A5B1 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 A5B1 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in A5B1 by 16⁰, multiply the second to last digit in A5B1 by 16¹, multiply the third to last digit in A5B1 by 16², multiply the fourth to last digit in A5B1 by 16³, and so on, until all the digits are used.

1 × 16⁰ = 1
B × 16¹ = 176
5 × 16² = 1280
A × 16³ = 40960

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 + 176 + 1280 + 40960 = 42417

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.

42417 ÷ 2 = 21208 with 1 remainder
21208 ÷ 2 = 10604 with 0 remainder
10604 ÷ 2 = 5302 with 0 remainder
5302 ÷ 2 = 2651 with 0 remainder
2651 ÷ 2 = 1325 with 1 remainder
1325 ÷ 2 = 662 with 1 remainder
662 ÷ 2 = 331 with 0 remainder
331 ÷ 2 = 165 with 1 remainder
165 ÷ 2 = 82 with 1 remainder
82 ÷ 2 = 41 with 0 remainder
41 ÷ 2 = 20 with 1 remainder
20 ÷ 2 = 10 with 0 remainder
10 ÷ 2 = 5 with 0 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 A5B1 hexadecimal to binary:

A5B1 hexadecimal = 1010010110110001 binary
