Yeah, and you're not French, so use Imperial.
Metric is scientifically standardised, Imperial isn't. It's got nothing to do with historical origin.
Imperial is also scientifically standardised, it's simply not internationally recognised. That's why you hear amusing stories about Mars probes crashing because one Nasa scientist was using miles, the other kilometres (doh).
It's sad that we adopted a French system really. Personally I find it easy to visualise an inch, or a foot - what on Earth is a metre other than "about 3 feet"
