Hi guys, Got a question on the naming of the kilo unit. Lets say ive got a battery at 1 kWh capacity, the k is lower case. However MWh, mega is capitalised, so is GWh, TWh. Now on the other end of the scale i can understand it is lower case, mWh, μWh, nWh. And for the large end of the scale, the symbols are upper case, except for kilo. So why is it not KW instead of kW?
