28FA hexadecimal to binary

Here we will show you how to convert the hexadecimal number 28FA 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 28FA from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 28FA by 16⁰, multiply the second to last digit in 28FA by 16¹, multiply the third to last digit in 28FA by 16², multiply the fourth to last digit in 28FA by 16³, and so on, until all the digits are used.

A × 16⁰ = 10
F × 16¹ = 240
8 × 16² = 2048
2 × 16³ = 8192

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:

10 + 240 + 2048 + 8192 = 10490

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.

10490 ÷ 2 = 5245 with 0 remainder
5245 ÷ 2 = 2622 with 1 remainder
2622 ÷ 2 = 1311 with 0 remainder
1311 ÷ 2 = 655 with 1 remainder
655 ÷ 2 = 327 with 1 remainder
327 ÷ 2 = 163 with 1 remainder
163 ÷ 2 = 81 with 1 remainder
81 ÷ 2 = 40 with 1 remainder
40 ÷ 2 = 20 with 0 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 28FA hexadecimal to binary:

28FA hexadecimal = 10100011111010 binary
