An amp-hour (or Ah, A·h, A h) of the electrical load, mAh (mAh) and mAh seconds (mAs). Any amp hour 3600 Coulomb (amp second) and electric charge passing through the constant flow of 1 amp for 1 hour is equal. Amp hours more to measure the system, electrochemistry such as electroplating and battery used. MAh (mAh or mA·h), that public more from the amp-hour is one thousandth of an amp-hour value.

mAh H, (mAs or mA·s) to measure the radiation X applied to the Vacationer in diagnostic imaging and radiotherapy. This quantity with all the energy of the beam, X, processed by tunnel with the voltage fixed, fits. Fixed Faraday is a mole of electrons and 26, the 8 amp-hour is equal. This is more for calculating, electrochemistry is used.

The thing is that the AMP hours a energy.
