**No, you dumb lap-dog. Trevor won't answer it for several reasons:

* I don't deal in Imperial measurements. No one on this planet does 
(except for a pitiful 5% of the planet's population). The Metric system 
is the only language scientists deal with.
* The Question is irrelevant to the discussion.
