Meters also can be marked as metres (in British English spelling).Definition: A meter, or metre (symbol: m), is the base unit of length and distance in the International System of Units (SI). The meter is a unit of length in the metric SI system and is 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). There are measurements of length/distance in the metric SI system greater than a meter that can be expressed in terms of metres.ġ m is equivalent to 3.28084 ft or 1.09361 yd.Units of length in the metric SI system are based on multiples or fractions of a meter.It is also the most popular unit for describing the retail estate distances and measurements (room sizes, floor measurements and so on).
The meter is commonly used in different trades and industries (for examle in machinery manufacturing), on road signs to indicate vehicle hight limits, the distance to short travel to a given location (for example in automotive GPS navigation voice prompts), on maps to indicate small scale, for vehicle, vessels and aircragt dimensions in industry and trade. In 1983 the final definition of meter was accepted as length of the path travelled by light in a vacuum in 1/299,792,458 of a second. In 1960 the meter was defined as 1,650,763.73 wavelengths of light from a specified transition in krypton-86. The meter gained popularity in continental Europe during the nineteenth century, particularly in scientific field, and was officially adopted as an international measurement unit in 1875. 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. Foot (ft) is a unit of Length used in Standard system.
