power to weigh is calculated by this equation -

Power / weight x 1000 (metric ton)

228 / 1265 x 1000 = 180.2371541501967284584980237512bhp

seems closer to 180 than 190 to me...

(power/(weight*0.0009842)*100)/100

thus making my calculation correct.

Correct Steve, neither are technically incorrect, but it is widely accepted that bhp/ton is measured metrically unless you are American.

But it doesn't matter if its metric or imperial, Chris has slightly more bhp/tonne (or ton, if were talking about imperial).

yes, but if they're both done using metric measurements, chris's GT has 0.7bhp per tonne more. which is neither here nor there.
