    Understanding battery capacity: Ah is not A

    - 23 August 2014

    Very well written report Jan! You've managed to explain technical stuff while keeping your language in common terms.

    Just an FYI to the readers who are new to electronics, that the AMPERE is just one of many SI units. The "Système International" was invented by a bunch of French scientists and they consolidated all the units in a way that you can very easily do mathematical conversions and calculations. Some examples:

    Water freezes at 0 degrees Celsius and boils at 100 degrees C.

    1 Gram of water = 1 milliLitre = 1 cubic centremetre
    So if i only had water and scales, i could work out Volume!

    By the way, the metric system is a part of the International System of Units. Americans really need to get with the times and ditch Imperial!
