m to AU

meter

• Definition: The meter is the fundamental unit of length in the International System of Units (SI). It is defined as the distance light travels in a vacuum in 1/299,792,458 seconds.

• Symbol: The symbol for meter is “m”.

• Usage: Meters are commonly used in various fields such as construction, science, and everyday measurements to quantify distances.

astronomical unit

• Definition: An astronomical unit (AU) is a unit of distance defined as the average distance from the Earth to the Sun, approximately 149.6 million kilometers.

• Symbol: The symbol for astronomical unit is “AU”.

• Usage: Astronomical units are primarily used in astronomy to describe distances within our solar system.

Origin of the meter

• The meter was initially introduced during the French Revolution in 1791. It was originally defined as one ten-millionth of the distance from the equator to the North Pole along the meridian through Paris. Over time, the definition has evolved to its current standard based on the speed of light.

Origin of the astronomical unit

• The concept of the astronomical unit dates back to the early 19th century. It was established as a convenient way to express distances in the solar system, particularly for calculating the orbits of planets. The current definition was solidified in the 20th century as more precise measurements of the Earth-Sun distance were achieved.
