19CD hexadecimal to binary

Here we will show you how to convert the hexadecimal number 19CD 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 19CD from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 19CD by 16⁰, multiply the second to last digit in 19CD by 16¹, multiply the third to last digit in 19CD by 16², multiply the fourth to last digit in 19CD by 16³, and so on, until all the digits are used.

D × 16⁰ = 13
C × 16¹ = 192
9 × 16² = 2304
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:

13 + 192 + 2304 + 4096 = 6605

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.

6605 ÷ 2 = 3302 with 1 remainder
3302 ÷ 2 = 1651 with 0 remainder
1651 ÷ 2 = 825 with 1 remainder
825 ÷ 2 = 412 with 1 remainder
412 ÷ 2 = 206 with 0 remainder
206 ÷ 2 = 103 with 0 remainder
103 ÷ 2 = 51 with 1 remainder
51 ÷ 2 = 25 with 1 remainder
25 ÷ 2 = 12 with 1 remainder
12 ÷ 2 = 6 with 0 remainder
6 ÷ 2 = 3 with 0 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 19CD hexadecimal to binary:

19CD hexadecimal = 1100111001101 binary
