1FAB hexadecimal to binary

Here we will show you how to convert the hexadecimal number 1FAB 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 1FAB from hexadecimal to binary are explained below.

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

B × 16⁰ = 11
A × 16¹ = 160
F × 16² = 3840
1 × 16³ = 4096

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:

11 + 160 + 3840 + 4096 = 8107

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.

8107 ÷ 2 = 4053 with 1 remainder
4053 ÷ 2 = 2026 with 1 remainder
2026 ÷ 2 = 1013 with 0 remainder
1013 ÷ 2 = 506 with 1 remainder
506 ÷ 2 = 253 with 0 remainder
253 ÷ 2 = 126 with 1 remainder
126 ÷ 2 = 63 with 0 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 1FAB hexadecimal to binary:

1FAB hexadecimal = 1111110101011 binary
