I am doing an assignment that is dealing with conversions. I've got it pretty well down now but I am doing a problem that requires converting octal to binary. If anyone could show me an example i would appreciate it. My overall goal is to convert Octal- 77777 into decimal. Thank you!'

Octal to binary
- Thread starter Chazm
- Start date
if you are going to decimal just expand the octal:
7 x 8^4 + 7 x 8^3 +7 x 8^2 + 7 x 8^1 +7 x 8^0
another way is to find 100000-(base8) and subtract 1
As for binary, 7-(base8) = 111-(base2). So five 7s in base8 would be five groups of 111s in base2.
77777-base8 = 111,111,111,111,111-base2
7 x 8^4 + 7 x 8^3 +7 x 8^2 + 7 x 8^1 +7 x 8^0

Each "octal" digit converts to three binary digits (the octal digits 0-7 convert to three-bit binary digits)
For example, convert 526(octal) to binary.
5 is 101 binary
2 is 010 binary
6 is 110 binary
so,
526 octal is 101 010 110 binary
Try that on your octal number.
