2730 octal to binary

Here we will show you how to convert the octal number 2730 to a binary number. First note that the octal number system has eight different digits (0 1 2 3 4 5 6 7) and the binary number system has only two different digits (0 and 1).

The four steps used to convert 2730 from octal to binary are explained below.

Step 1)
Multiply the last digit in 2730 by 8⁰, multiply the second to last digit in 2730 by 8¹, multiply the third to last digit in 2730 by 8², multiply the fourth to last digit in 2730 by 8³, and so on, until all the digits are used:

0 × 8⁰ = 0
3 × 8¹ = 24
7 × 8² = 448
2 × 8³ = 1024

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

0 + 24 + 448 + 1024 = 1496

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.

1496 ÷ 2 = 748 with 0 remainder
748 ÷ 2 = 374 with 0 remainder
374 ÷ 2 = 187 with 0 remainder
187 ÷ 2 = 93 with 1 remainder
93 ÷ 2 = 46 with 1 remainder
46 ÷ 2 = 23 with 0 remainder
23 ÷ 2 = 11 with 1 remainder
11 ÷ 2 = 5 with 1 remainder
5 ÷ 2 = 2 with 1 remainder
2 ÷ 2 = 1 with 0 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 2730 octal to binary:

2730 octal = 10111011000 binary
