Historical documentation from inter/national standards organizations trump an incorrect textbook any day (read the article discussion if you're really interested, and want links to truly authoritative documentation). I'm surprised that you would think wikipedia is in any way authoritative. Of course, this _is_ the Vanagon list, and no one here but you would even think of using coulombs for measuring Vanagon-y things. Battery capacities are measured in amp-hours, and multimeters measure volts-ohms-amperes. I've yet to see one which will display coulombs. |
