In the eighteenth century, there were two favoured approaches to the definition of the meter. One approach suggested that the metre be defined as the length of a 'seconds pendulum' (pendulum with a half-period of one second). Another suggestion was defining the metre as one ten-millionth of the length of the Earth's meridian along a quadrant (the distance from the Equator to the North Pole).
In 1791, the French Academy of Sciences selected the latter definition (the one related to Earth's meridian) over the former (the one with the pendulum) because the force of gravity varies slightly over the surface of the Earth's surface, which affects the period of a pendulum.

How was the stardard meter defined in 1791?
As 10 dm. A cubic dm (deci-meter) cube happens to be able to contain exactly 1 liter of water at 20 degrees C. with cats
The meter is defined as?
A meter is currently defined as the length of the path travelled by light in vacuum during a time interval of 1 / 299,792,458 of a second.
Why is a meter a meter long?
A meter is defined as the distance travelled by light in free space in 1/299,792,458th of a second.
How was the length of the standard meter defined defined in the year 1791?
The metre was originally intended to be one ten-millionth of the distance from the equator to the north pole running through Paris (making the distance from the equator to the north pole 10,000 km and the circumference of the earth 40,000 km [round that great circle]). It has since been redefined
Arrangement of a line of poetry defined by the number of syllables and rhythm is?
meter
How was lenght of a standard meter defined in the year 1791?
by the demension of the planet earth
How was the stardard meter defined in 1791?

What was the length of a meter in the year 1791?
The meter was invented in 1791. As being 1/10,000,000 of the distance from the North Pole to the equator.
What is the meter defined by?
the meter is defined as the basic unit of the metric unit.
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 a standard meter could be cast in metal.
How was meter first defined?
the meter is defined as distance that travels 1/299792458
When did the word meter become used as a measurement term?
It was established in 1791.
The meter is defined as?
A meter is currently defined as the length of the path travelled by light in vacuum during a time interval of 1 / 299,792,458 of a second.
Why is a meter a meter long?
A meter is defined as the distance travelled by light in free space in 1/299,792,458th of a second.
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.
What is the meter defined as?
A metre is defined as the distance light will travel in 1/299 792 458 seconds in a vacuum.
What is the exact length of a Meter?
A meter is defined to be the distance travelled by light in 1/299,792,458 of a second.
