text: and the problem is that we tried to convert everything from inches to centimeters preserving basically the inches but expressing them as centimeters rather than saying no a centimeter is about the width of your thumbnail or whatever and you know and leaving it at that and uh you know a kilogram weighs about this much and get used to it from scratch cause i still can 't convert back and forth from inches to centimeters but i 'm perfectly comfortable using either
