Can you tell me how a home's electric meter works, in order to calculate my electricity usage?

An electric meter measures the total electricity used in a household by recording the amount of electricity passed through the meter on a standardized measurement scale. The device usually looks like a small rectangular box mounted on or beside the wall outside of the home, and typically has two or three meters, measuring respectively for electricity, gas, and water usage. Inside the meter are two electrodes set at an angle to each other, with an electric circuit linking the two. When current flows through the meter, it rotates to record the number of electrons that have flown past it, which is then translated into kilowatt-hours (kWh). The more electricity used, the higher the rotational speed of the dial on the electric meter.
