Google is a good answer - it will respond to a simple 'convert' question, eg '1 cm in inches', or, in answer to your question:
1 (cubic foot) = 0.0283168466 cubic meters
or
1 (cubic meter) = 35.3146667 cubic feet
depending on which way round you put it.
I assume you know Google also responds to a 'define' command for words, which is define: < the word you're looking for>
