Octal to Binary Conversion
So the process to convert Octal to binary is a simple one. As we have established earlier an Octal number is equivalent to three binary bits. So, what we have to do is first convert each digit into its binary equivalent.
Example: Convert 2138 to a binary number.
Write the corresponding binary value of each digit of the given octal number:
2 —> 010
1 —> 001
3 —> 011
Hence we get 2138 = 0100010112
What is Octal ?
Octal is a number system with a base of 8 i.e. it uses 8 numeric values, namely, {0, 1, 2, 3, 4, 5, 6, 7}. This number system is mostly used in the programming of computer programs. For example (32150.7642)8, (275)8, (324)8, (2243)8 are Octal numbers. In this article, we will discuss the octal number system.
