Convert binary to octal

Answer 1

To convert a binary number of an octal number, group each set of three bits into a group, starting from the right. Then, convert each group into its decimal equivalent. A 1 in the leftmost bit is a 4, a one in the middle bit is a 2, and a one in the right bit is a 1. For example, 101 is 4+0+1, or 5. Grouping should be as follows:

Binary: 0011010011010110

Grouped: 0 011 010 011 010 110

Octal: 032326

You may also find programs that will perform this conversion for you. Windows Calculator can perform this translation for you when using the advanced mode that shows binary/hex/octal options.

Answer 2

This is actually very simple: convert each octal digit to a group of 3 binary digits. Example:

453 (octal) = 010 101 011 (binary).

You would normally leave out the spaces between the digits; I only put them there to emphasize that each group of three binary digits came from a single octal digit.
