The length unit meter is the SI unit used to define a distance. Originally it was defined based on the distance from the equator to the north pole and 1 meter corresponded to 1 part in 10 million of this distance measured along the sea level.

Today, however, the length unit of 1 m is much more precisely and strictly defined. Instead of using our earth as the defining object, 1 m is actually defined as the length light travels during 1/299792458 s in vacuum.

I hope this answers your question about the meter unit.

A meter, abbreviated m, is the Standard International (SI) unit of length; it is the fundamental unit of length in metric system.

One meter (1m) is the distance (length) traveled by light in vacuum in 3.33564095*10^ -9 of a second.

In relation to other units:

1m = 100cm (centimeters)

1m = 39.37 inches

1000m = 1km (Kilometer)

One meter one thousandth of a kilometer. There are a hundred centimeters in a meter. A meter is equal to approximately 3.2 feet. A meter is almost 60 percent of average human height. A meter is the distance a light ray can travel in vacuum in a time duration of approximately 3.3 nanoseconds or 1/299792458 th of a second (~ three hundred millionth of a second).

...The French originated the meter in the 1790s as 1/ten-millionth of the distance from the Equator to the North Pole along a meridian through Paris. It is realistically represented by the distance between two marks on an iron bar kept in Paris. The International Bureau of Weights and Measures upgraded the bar to one made of 90 % platinum and10 % iridium alloy.

...A meter is about 3.28 feet.

A meter is just about 3 inches longer than a yard.

So to get a mental picture in your mind, just think of the length of a yard stick add 3 more inches.

Hope this makes it easy for you.
