7A1 hexadecimal to binary

Here we will show you how to convert the hexadecimal number 7A1 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 7A1 from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 7A1 by 16⁰, multiply the second to last digit in 7A1 by 16¹, multiply the third to last digit in 7A1 by 16², multiply the fourth to last digit in 7A1 by 16³, and so on, until all the digits are used.

1 × 16⁰ = 1
A × 16¹ = 160
7 × 16² = 1792

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 + 1792 = 1953

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.

1953 ÷ 2 = 976 with 1 remainder
976 ÷ 2 = 488 with 0 remainder
488 ÷ 2 = 244 with 0 remainder
244 ÷ 2 = 122 with 0 remainder
122 ÷ 2 = 61 with 0 remainder
61 ÷ 2 = 30 with 1 remainder
30 ÷ 2 = 15 with 0 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 7A1 hexadecimal to binary:

7A1 hexadecimal = 11110100001 binary
