1) What's a "foreign country" depends on who is reading your mail. By 
"foreign country" I assume you mean the entire world except for the US and 
Liberia, these being the only places still using inch measurements.  IMO, 
when sending email worldwide, it is usually best to avoid ethnocentric 
terms such as "foreign" and "alien". Note: Most US scientists "went metric" 
over 40 years ago, although US engineers did not. (this was the basis of 
the last Mars Lander disaster)

2) I don't think you really meant     " p = input power in inches"
