II Read text and define the main idea of it: meter

The meter is the international unit of displacement or length. One meter is the distance traveled by a ray of electromagnetic energy through a vacuum in 1/299,792,458 (3.33564095 x 10-9) of a second. The meter was originally defined as one ten-millionth (0.0000001 or 10-7) of the distance, as measured over the earth's surface in a great circle passing through Paris, France, from the geographic North Pole to the equator.

One meter is a little more than three English feet, or about 39.37 inches. One foot is approximately 0.3048 meter. There are about 1609 meters in a statute mile. The official span was at one time formally defined as the separation between two scratches on a platinum bar in Paris. This was, of course, intended mainly for show, and not for use in the laboratory.

In engineering applications and also in an everyday sense, the term meter refers to any instrument used to measure the magnitude of a quantity. Examples include the volume-unit meter in home audio systems, the ammeter to measure electric current, and the kilowatt-hour meter to measure electrical energy consumed over a period of time.
