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.
A meter is defined as the distance travelled by light in free space in 1/299,792,458th of a second.
meter
From Wikipedia: "Since 1983, [the metre] is defined as the distance travelled by light in vacuum in 1⁄299,792,458 of a second." This is the currently used definition.
One square meter is defined as the area of a square with sides that are each one meter long. Therefore, 1 meter is simply a linear measurement and does not directly convert to square meters. However, if you consider a square that is 1 meter by 1 meter, it encompasses an area of 1 square meter.
In a hole that is 1 meter wide, 1 meter deep, and 1 meter long, there is no dirt because a hole is defined by the absence of material. Therefore, the volume of the hole is 1 cubic meter, but it contains zero dirt.
the meter is defined as the basic unit of the metric unit.
the meter is defined as distance that travels 1/299792458
A meter is defined as the distance travelled by light in free space in 1/299,792,458th of a second.
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.
The meter is defined as the distance traveled by ? in absolute vacuum in 1299792458 of a second.
1 meter is one forty-millionth of the polar circumference of Earth.
meter
A meter is defined to be the distance travelled by light in 1/299,792,458 of a second.
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.

He didn't. The newton unit is defined as a kilogram-meter per second squared, meaning it does not predate the invention of the kilogram, meter, and (scientifically defined) second. The international prototype kilogram was standardized in 1889, so the newton does not predate this year, at least.
