We tried to convert from inches to centimeters.
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
