Feature Requests: Preferred Measurement Units - kg/miles

It might seem a bit of a bizarre combination, but I'd like to see an option to use kg and miles as my preferred units (at present, the options are imperial, metric, or hybrid lb/km).

I'm sure I'm not the only Englishman never to use lb. Even when imperial weights are used - which is less and less often because of European influence - they'd be combined stones/lb/oz rather than just pounds. Would be far easier to allow a combination of miles for distance and kilos for weight.

All the best
