128E hexadecimal to octal

Here we will show you how to convert the hexadecimal number 128E to an octal 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 octal number system has only eight different digits (0 1 2 3 4 5 6 7).

The four steps used to convert 128E from hexadecimal to octal are explained below.

Step 1)
Multiply the last digit in 128E by 16⁰, multiply the second to last digit in 128E by 16¹, multiply the third to last digit in 128E by 16², multiply the fourth to last digit in 128E by 16³, and so on, until all the digits are used.

E × 16⁰ = 14
8 × 16¹ = 128
2 × 16² = 512
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:

14 + 128 + 512 + 4096 = 4750

Step 3)
Now we divide the sum from Step 2 by 8. Put the remainder aside. Then divide the whole part by 8 again, and put the remainder aside again. Keep doing this until the whole part is 0.

4750 ÷ 8 = 593 with 6 remainder
593 ÷ 8 = 74 with 1 remainder
74 ÷ 8 = 9 with 2 remainder
9 ÷ 8 = 1 with 1 remainder
1 ÷ 8 = 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 128E hexadecimal to octal:

128E hexadecimal = 11216 octal
