Convenient for Amazon shopping, cooking, etc.

Inch, Feet, Yard, Mile -> Metre (Meter)
Pound, Ounce, Stone -> Kilogram
Gallon, Quart, Pint, Fluid Ounces, Cups -> Litre (Liter)

Area conversion for ft, yd, in, mi, both as "sq. ft" and "ft²" (must not be superscript); the same is for volume conversion.
