If the data stream is stored it will be an array of current samples and an array of timestamps. If data are available in series then just take a difference operation on the timestamp array which gives the width of each rectangle in the series and then multiply this by the current sample for that period (this assumes current is constant for a short period) so this is the width (time) times height (current) in your sample data. Then sum all these products to get the measured area and then convert to other units. | |

In the short run, it's not a big deal tho but after few hours it makes a huge difference as I explained in one of the comments above. I would rather going to include the runtime in the calculation average mA * runtime(s) / 3600. I hope I'm not wrong here. | |
