7FA1 hexadecimal to binary

Here we will show you how to convert the hexadecimal number 7FA1 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 7FA1 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 7FA1 by 16⁰, multiply the second to last digit in 7FA1 by 16¹, multiply the third to last digit in 7FA1 by 16², multiply the fourth to last digit in 7FA1 by 16³, and so on, until all the digits are used.

1 × 16⁰ = 1
A × 16¹ = 160
F × 16² = 3840
7 × 16³ = 28672

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 + 160 + 3840 + 28672 = 32673

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.

32673 ÷ 2 = 16336 with 1 remainder
16336 ÷ 2 = 8168 with 0 remainder
8168 ÷ 2 = 4084 with 0 remainder
4084 ÷ 2 = 2042 with 0 remainder
2042 ÷ 2 = 1021 with 0 remainder
1021 ÷ 2 = 510 with 1 remainder
510 ÷ 2 = 255 with 0 remainder
255 ÷ 2 = 127 with 1 remainder
127 ÷ 2 = 63 with 1 remainder
63 ÷ 2 = 31 with 1 remainder
31 ÷ 2 = 15 with 1 remainder
15 ÷ 2 = 7 with 1 remainder
7 ÷ 2 = 3 with 1 remainder
3 ÷ 2 = 1 with 1 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 7FA1 hexadecimal to binary:

7FA1 hexadecimal = 111111110100001 binary
