I fully support the change to metric units. - the international metric system is more than 200 years old. At the origin, all countries agreed to adopt the Greenwich (British/american) meridian as a reference, and, in exchange, the metric unit system first developed in France. After 200 years, the non British/American have long ago adopted the Greenwich meridian, but the "imperial" unit system is still in use; The move to metric is well advanced in England. I thought that is was mandatory according to the laws in the US... - the mixed use of metric/imperial units has costed hundreds millions dollar to the US, when they lost at least 2 satellites (to Mars) because NASA and GPL didn't used the same units system; - the metric is much simpler to use, in particular when the scale is different. What is the force on a square foot when the pressure is given in psi... - ... On the other side, I would NOT support a fork. There is enough work still to be done for new stations, new skins etc. Let's keep ONE weewx, is it such a powerful and useful tool!
