What terms was standard meters defined in on 1983?
Originally, a metre was defined as 1/10,000,000th of the distance from the Earth's equator to the North pole. Since 1983 it has been defined as:the length of the path travelled by light in a vacuum during a time interval of 1/299,792,458th of a second.
What is the scientific meaning of meter?
The scientific meaning of meter was originally defined as one ten-millionth (0.0000001 or 10-7) of the distance from the Earth's equator to the North Pole. However, it is now defined as being the length of the path traveled by light in a vacuum during a time interval of 1/299,792,458 of a second.
What is the scientific definition of the meter?
The meter is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second.The distance light travels in a vacuum in 1/299,792,458 of a second is the offcial definition of a meter.
What is the exact length of a Meter?

What is the internationally accepted definition of the meter?
The main impact of the metric system is that it has been standardized so that the meter, kilogram, Celsius degree, second (and other dimensional standards) are standardized worldwide. Having units relate in powers of ten makes for convenience.

Define a centimeter and a millimeter?
A meter is the distance light travels in a vacuum in 1/299,792,458 seconds, so a centimeter is this distance divided by 100 and a millimeter is this distance divided by 1000.
How was the length of a meter redefined in the year 1983?
On October 20, 1983, the meter was officially redefined as the distance traveled by light in a vacuum during a time interval of 1/299,792,458 of a second.Light travels at 299792.458 km/sec, so the period was chosen as 0.00000000335641 second, or 3.35641 x 10-9 second.The original definitions (1799 and 1899) depended on a measured standard bar. In 1960, it was redefined as a relationship to the wavelength of light from ions of the element krypton. In 1980, the standard was based on the unusually cohesive wavelength of an iodine-stabilized helium-neon laser.
What does The International Committee on Weights and Measures designates the speed of light as?
They don't designate the speed of light, but they do define the meter as1/299,792,458 of the distance that light travels in one second in vacuum.
