1201 octal to binary

Here we will show you how to convert the octal number 1201 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 1201 from octal to binary are explained below.

Step 1)
Multiply the last digit in 1201 by 8⁰, multiply the second to last digit in 1201 by 8¹, multiply the third to last digit in 1201 by 8², multiply the fourth to last digit in 1201 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
0 × 8¹ = 0
2 × 8² = 128
1 × 8³ = 512

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

1 + 0 + 128 + 512 = 641

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.

641 ÷ 2 = 320 with 1 remainder
320 ÷ 2 = 160 with 0 remainder
160 ÷ 2 = 80 with 0 remainder
80 ÷ 2 = 40 with 0 remainder
40 ÷ 2 = 20 with 0 remainder
20 ÷ 2 = 10 with 0 remainder
10 ÷ 2 = 5 with 0 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 1201 octal to binary:

1201 octal = 1010000001 binary
