The 'B' in BHP stands for 'brake'. So on a "rolling road" the dials show
the figures as power against the rolling road brake.
To be honest, I'm not sure how a brake horse power is measured, although I'm
sure a quick search on the internet could yield me both the imperial and
metric version.
I just see it as a figure. So in the same way I could gauge the
"econominess" of MPG I can also gauge the powerfulness of BHP. I believe
that the BHP in the UK follows the same standard.
The most powerful car I've had (Jag) had over 400BHP, but thanks to it being
a cabrio, auto-box and heavy it was not the fastest car I ever had (lotus)
which packed over 50BHP less but got to 60 (mph) in just over 4 (seconds).
BTW - There is two different ways of measuring BHP:- "at the wheels" and the
higher "at the flywheel". Some prefer to work in the latter whereas some
(including me) prefer the former.

How does BHP differ from plain HP? Would a BHP number be higher then an HP
number? How many BHP is there in a watt?

A real deception would be to drop in BGP instead of BHP. (Brake Goat
Power).
My mini pulls 420 BGP !

This has happened with the calorie, which is one reason why the calorie
isn't
in SI.
