In 1795 the meter was defined as 1/10,000,000 part of the quarter of a meridian, passing through Paris. The new unit of length was introduced which became known as the meter. The meter (metre in UK spelling) is a unit of length/distance in the metric system (SI Unit system) equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983).ġ m is equivalent to 3.28084 ft or 0.000621371 miles.Īs a result of the French Revolution in 1789, the old units of measure that were associated with the monarchy were replaced by the new units. Primary exceptions are the United States of America, and some countries where feet and yards are used in limited extent: the United Kingdom and Canada, where the yard remains in limited use as a part of imperial system (for example, yards are used on road signs for shorter distances in the United Kingdom and feet are widely used in construction and real estate in Canada). The meter is widely used in most countries and is the official unit for medium lengths and distances (for example, road signs in continental Europe show maximum vehicle hight in meters).
It's a standard measure for short distances (up to 1 km long), in real estate and construction, supply materials, vehicle and aircraft dimensions, short geographical distances and directions in most countries excluding the USA where foot and yard are still widely used for this purpose. The meter is used as a unit to measure medium distances or lengths. Meter (m) is a unit of Length used in Metric system.įoot (ft) is a unit of Length used in Standard system.
