Definition: A meter, or metre (symbol: m), is the base unit of length and distance in the global System of devices (SI). The meter is characterized as the distance traveled by light in 1/299 792 458 the a second. This definition was slightly modified in 2019 come reflect transforms in the meaning of the second.

History/origin: Originally, in 1793, the meter was defined as one ten-millionth of the distance from the equator to the phibìc Pole. This changed in 1889, as soon as the international prototype metre was developed as the length of a prototype meter bar (made of an alloy the 90% platinum and 10% iridium) measured in ~ the melting point of ice. In 1960, the meter was again redefined, this time in terms of a certain number of wavelengths of a specific emission heat of krypton-86. The current definition of the meter is properly the exact same as the an interpretation that was embraced in 1983, v slight modifications due to the adjust in meaning of the second.
Current use: gift the SI unit that length, the meter is used worldwide in many applications such together measuring distance, height, length, width, etc. The United says is one notable exception in the it mostly uses us customary systems such together yards, inches, feet, and also miles instead of meters in day-to-day use.
Definition: A millimeter (symbol: mm) is a unit of size in the international System of systems (SI). That is identified in terms of the meter, together 1/1000 that a meter, or the street traveled by irradiate in 1/299 792 458 000 that a second.

History/origin: The milli- prefix is one of plenty of metric prefixes. It suggests one thousandth of the base unit, in this situation the meter. The an interpretation of the meter has changed over time, the current meaning being based on the street traveled by the speed of light in a given amount the time. The relationship between the meter and also the millimeter is constant however. Prior to this definition, the meter was based upon the size of a prototype meter bar. In 2019, the meter has actually been re-defined based on the alters made to the an interpretation of a second.
