So did you ask them if they have any data in SI units only?

Thought I would send you all this email from Pratt & Whitney Canada.
I"m in school on a new aircraft and the engine information in a P&W
brochure gave Thrust as 6400 Fn and Thermodynamic 7630 Fn. I had no idea what
these units were, so I wrote to their customer service in Montreal who
forwarded me the attached file, you'll see it has a mishmash of units,
Fahrenheit only, Celsius only, basically no SI except for Celsius. Fn is
apparently their abbreviation for Pound Thrust, anyone have any idea where they
might have got this weird abbreviation from?
Mike Payne
Michael,
The abbreviation Fn that PWC uses is for net thrust in lbs. I have
attached an engine overview file that should answer most of your
questions. For specific operating limits please refer to the engine
maintenance manual chapter 05-10-00.
Best Regards,
Jean Marc Saulnier

I cannot find anything on this engine on your web site.
I'm at school on the Falcon 7X with Pratt & Whitney 307A engines, the
information we have is incomplete. The handout States Thrust 6400 Fn,
what is this? Femto Newtons? Do you have any information that gives
better information. I'm fine with data in SI, just give me the correct
units.
