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 Megaparsecs
A megaparsec (Mpc) is one million parsecs or 3.26 million light years, the standard unit for measuring intergalactic distances. The Andromeda Galaxy is about 0.77 megaparsecs away, while most galaxies in the observable universe are measured in megaparsecs. The Local Group of galaxies spans about 3 megaparsecs. Astronomers use megaparsecs in combination with redshift measurements to calculate distances to distant galaxies and study the expansion of the universe. The Hubble constant, describing cosmic expansion, is expressed in kilometers per second per megaparsec.
