The cube of a binary number is called an octal number. To convert a binary to its equivalent octal number, the given binary number is divided into groups, each set of numbers should contain three binary bits, and then each group is converted to its equivalent octal number. . The following example lets you understand that octal conversion to binary 。</P> <P align="left">Example: Binary number (111110011001)<SUB>2</SUB> Convert to its equivalent octal </P> <P>Equivalent</P> <p align="center">
