What terms was standard meters defined in on 1983?
Since 1983 the meter has been defined as the distance light.
How was the length of a standard meter defined in the year 1719?
The standard meter (metre) was not defined in 1719. It was not until the 1790's that it was set as a standard. It was proposed that the metre would be defined as one ten millionth the distance from the earth's north pole to the equator as measured along a meridian. There is a good explanation here: http://en.wikipedia.org/wiki/Meter ...
How was the length of the standard meter defined in the year 1791?
by the dimensions of the planet earth

Unit of measurement uniformily used by everyone?
A standard measurement is one that is accepted and used by everyone. If the measurement can be compared to some standard, which does not changes, then it can be universally used. One example is a unit of time such as seconds, minutes, hours, days, years. The meter has a standard, and the foot and inch are defined in reference to the meter. ...
How was the length of a standard meter defined in the year 1791?
In the 18th century it was felt that a standard unit of length was needed. The French Academy of Sciences decided in 1791 that the meter would be defined by the dimensions of the planet earth. The metre would be a unit of length such that Earth's meridian line (a line linking the equator with the north pole) was equal to ten million meters. Over the following years measurements of the meridian line that passes through Paris were attempted, so that...

Asked in Physics
Why do scientists keep revising the definition of the meter?
As scientists study new areas the meter is involved in these new areas and new definitions in terms of the new areas are defined. The original meter was defined in terms of the earth studies, as electricity was studied, the speed of light became important and the meter was defined in terms of the speed of light. As science expands the definitions of the meter will expand. ...
