    That’s great and all. But by measuring everything in millimetres and grams you miss out on the very thing that makes the metric system great; the easy conversions. You can measure things in millimetres and easily switch to centimeters, just by moving the decimal sign, when the measurement gets large enough. That way you can almost always keep the numbers manageable. No need to say 1500 millimetres. Just say 1,5 m.

      Weight as well. One liter is exactly 1kg of water. In precipitation (rain amount) 1mm is exactly 1l or 1kg of water on 1m². So when they say there will be 8mm of fall, that’s expected around 8l per square meter which is quite intuitive.
