12420 octal to hexadecimal

Here we will show you how to convert the octal number 12420 to a hexadecimal number. First note that the octal number system has 8 different digits (0 1 2 3 4 5 6 7) and the hexadecimal number system has 16 different digits (0 1 2 3 4 5 6 7 8 9 A B C D E F).

The four steps used to convert 12420 from octal to hexadecimal are explained below.

Step 1)
Multiply the last digit in 12420 by 8⁰, multiply the second to last digit in 12420 by 8¹, multiply the third to last digit in 12420 by 8², multiply the fourth to last digit in 12420 by 8³, and so on, until all the digits are used:

0 × 8⁰ = 0
2 × 8¹ = 16
4 × 8² = 256
2 × 8³ = 1024
1 × 8⁴ = 4096

Step 2)
Next, we add up all the products we got from Step 1, like this:

0 + 16 + 256 + 1024 + 4096 = 5392

Step 3)
Now we divide the sum from Step 2 by 16. Put the remainder aside. Then divide the whole part by 16 again, and put the remainder aside again. Keep doing this until the whole part is 0. (Also, replace remainders if need be: 10=A, 11=B, 12=C, 13=D, 14=E, and 15=F).

5392 ÷ 16 = 337 with 0 remainder
337 ÷ 16 = 21 with 1 remainder
21 ÷ 16 = 1 with 5 remainder
1 ÷ 16 = 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 12420 octal to hexadecimal:

12420 octal = 1510 hexadecimal
