I can't remember if I posted something along these lines before. I think the metric (SI) is better to work with than imperial. However, the basic units seem a bit sort of arbitrary. I think the original kilogram was the weight of a litre of water (maybe it wasn't). A degree Celsius is a hundredth of the difference between water's boiling and freezing point. A metre is a fraction of the earth's circumference iirc. These are not universal constants. I wondered what better units there may be. Iirc, there are 6 things to measure: length, time, mass, electric charge, temperature, and luminosity. I reckon the speed of light could be used to determine the distance unit if there was a good candidate for the time unit. The charge of an electron could be used as the unit for electrical charge. What would be the sensible multiplier: 10 like metric, 2 like computer science, e like in maths?
