About Meters
The meter (m) is the fundamental unit of length in the International System of Units (SI) and is used worldwide. Originally defined as one ten-millionth of the distance from the Earth's equator to the North Pole, it's now precisely defined as the distance light travels in a vacuum in 1/299,792,458 of a second. A meter is roughly the height of a kitchen counter, the width of a large door, or one large step for an adult. Most countries use meters for measuring room sizes, building heights, and short distances.
About Astronomical Units
An astronomical unit (AU) is the average distance between Earth and the Sun, precisely defined as 149,597,870.7 kilometers. This unit provides a convenient scale for measuring distances within our solar system. Mars orbits at 1.5 AU, Jupiter at 5.2 AU, and Neptune at about 30 AU from the Sun. The dwarf planet Pluto reaches up to 49 AU away. Light takes about 8.3 minutes to travel 1 AU, explaining why we see the Sun as it was 8 minutes ago. The AU is fundamental in astronomy and space exploration.
