A51F hexadecimal to binary

Here we will show you how to convert the hexadecimal number A51F 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 A51F from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in A51F by 16⁰, multiply the second to last digit in A51F by 16¹, multiply the third to last digit in A51F by 16², multiply the fourth to last digit in A51F by 16³, and so on, until all the digits are used.

F × 16⁰ = 15
1 × 16¹ = 16
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:

15 + 16 + 1280 + 40960 = 42271

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.

42271 ÷ 2 = 21135 with 1 remainder
21135 ÷ 2 = 10567 with 1 remainder
10567 ÷ 2 = 5283 with 1 remainder
5283 ÷ 2 = 2641 with 1 remainder
2641 ÷ 2 = 1320 with 1 remainder
1320 ÷ 2 = 660 with 0 remainder
660 ÷ 2 = 330 with 0 remainder
330 ÷ 2 = 165 with 0 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 A51F hexadecimal to binary:

A51F hexadecimal = 1010010100011111 binary
