3ECA hexadecimal to octal

Here we will show you how to convert the hexadecimal number 3ECA 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 3ECA from hexadecimal to octal are explained below.

Step 1)
Multiply the last digit in 3ECA by 16⁰, multiply the second to last digit in 3ECA by 16¹, multiply the third to last digit in 3ECA by 16², multiply the fourth to last digit in 3ECA by 16³, and so on, until all the digits are used.

A × 16⁰ = 10
C × 16¹ = 192
E × 16² = 3584
3 × 16³ = 12288

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 + 192 + 3584 + 12288 = 16074

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.

16074 ÷ 8 = 2009 with 2 remainder
2009 ÷ 8 = 251 with 1 remainder
251 ÷ 8 = 31 with 3 remainder
31 ÷ 8 = 3 with 7 remainder
3 ÷ 8 = 0 with 3 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 3ECA hexadecimal to octal:

3ECA hexadecimal = 37312 octal
