11001 octal to binary

Here we will show you how to convert the octal number 11001 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 11001 from octal to binary are explained below.

Step 1)
Multiply the last digit in 11001 by 8⁰, multiply the second to last digit in 11001 by 8¹, multiply the third to last digit in 11001 by 8², multiply the fourth to last digit in 11001 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
0 × 8¹ = 0
0 × 8² = 0
1 × 8³ = 512
1 × 8⁴ = 4096

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

1 + 0 + 0 + 512 + 4096 = 4609

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.

4609 ÷ 2 = 2304 with 1 remainder
2304 ÷ 2 = 1152 with 0 remainder
1152 ÷ 2 = 576 with 0 remainder
576 ÷ 2 = 288 with 0 remainder
288 ÷ 2 = 144 with 0 remainder
144 ÷ 2 = 72 with 0 remainder
72 ÷ 2 = 36 with 0 remainder
36 ÷ 2 = 18 with 0 remainder
18 ÷ 2 = 9 with 0 remainder
9 ÷ 2 = 4 with 1 remainder
4 ÷ 2 = 2 with 0 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 11001 octal to binary:

11001 octal = 1001000000001 binary
