"2m" refers to a measurement of two meters, which is equivalent to approximately 6.56 feet. It is commonly used in various fields, including construction, sports, and everyday life, to indicate distance or height. For example, a standard basketball hoop is set at a height of 3.05 meters, making it about half the height of a typical room ceiling. In the context of social distancing, "2m" became a widely recognized guideline during the COVID-19 pandemic. This distance was recommended to help reduce the spread of the virus by minimizing close contact between individuals. Many public spaces, including restaurants and stores, implemented signage to remind people to maintain this distance.
