As cited earlier by someone else, the conversions and an on-line calculator are all listed at http://www.rceng.com/ and click the link Online Fuel Injector Flow Rate Worksheet!

You can highlight all that web page and copy and paste it into a Word document to save or print and use for a reference.

Thanks. I follow that. So with 4 of these 550cc suckers going full belt I'd
be capable of expelling 52/6 * 4 = 34.67 gals/hr. Seems a bit excessive!
Also - does fuel pressure factor into the equasion?
