99A5 hexadecimal to octal

Here we will show you how to convert the hexadecimal number 99A5 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 99A5 from hexadecimal to octal are explained below.

Step 1)
Multiply the last digit in 99A5 by 16⁰, multiply the second to last digit in 99A5 by 16¹, multiply the third to last digit in 99A5 by 16², multiply the fourth to last digit in 99A5 by 16³, and so on, until all the digits are used.

5 × 16⁰ = 5
A × 16¹ = 160
9 × 16² = 2304
9 × 16³ = 36864

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:

5 + 160 + 2304 + 36864 = 39333

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.

39333 ÷ 8 = 4916 with 5 remainder
4916 ÷ 8 = 614 with 4 remainder
614 ÷ 8 = 76 with 6 remainder
76 ÷ 8 = 9 with 4 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 99A5 hexadecimal to octal:

99A5 hexadecimal = 114645 octal
