FAQ
How do I convert binary to octal?
Multiply the binary value by the conversion factor: read the digits as base 2, then re-encode in base 8. This calculator applies the exact factor automatically and rounds the display to ten significant figures.
How do I convert octal back to binary?
Divide by the same factor — conversion factors work in both directions, so the reverse calculation is just the inverse of the forward one.
How accurate is this binary to octal conversion?
The math runs on exact SI definitions and international standard factors, with results rounded only for display (ten significant figures). That is far tighter than any practical measurement tolerance.
