Megameter (Mm)
Definition: A megameter (Mm) is a unit of length equal to one million meters (10^6 meters). It is used to measure large distances in both geography and astronomy.
History: The megameter was introduced alongside other metric units to standardize measurements of large distances. It has been mainly used in astronomical contexts to simplify expressions of distances in space.
Current Use: Megameters are used in astronomy to describe distances between astronomical objects such as the Earth and the Sun. They also appear in some applications in geology and planetary science.
Yard (yd)
Definition: A yard (yd) is a unit of length equal to 0.9144 meters or three feet. It is commonly used in construction, sports fields, and textile measurements, particularly in the US and UK.
History: The yard originated in medieval England, standardized by King Henry I. It was originally based on the length of a man's belt or the distance from the nose to the thumb tip.
Current Use: Yards are widely used in the US and UK for measuring land, fabric, and sports fields, including American football. They are also commonly seen in real estate and landscaping measurements.
