When I moved to France way back when, one of the first things I set out to buy was a kitchen scale. Kitchen scales are not difficult to find in Europe because most of the countries use weights for baking and in every other type of recipe. In spite of their ubiquity, it was hard to find a scale that measured in both in grams and kilos as well as ounces and pounds. Since few use those standards of measurement in Europe, even kitchen scales that I’d used in America would have a little toggle switch somewhere on them (often on the underside) to shift back and forth between ounces and grams. But whenever I looks at scales in Europe, there was invariably a gaping hole where that switch would be.
(I always thought it odd that they would leave a switch off the same kitchen scale that they make for one part of the world and not the other. Seems to me that it would be easier to make one scale for everyone. But on the other hand, it would also be easier if everyone used the same system of measurement.)
