A meter is the SI Unit for length. The definition of a meter has changed dramatically over the years. A meter is approximately a yard. Many students look at a meter stick that has a yard stick on the opposite side - and get confused. Use the correct side!
KHS Students: Read page 121 of your text and find out just how much the definition of a meter has changed since the early definition that it should be one ten-millionth of the distance from the North Pole to the equator. Since 1983, the definition is that a meter is the distance light travels in 1/299,792,458 second.
