2meter

2meter (two meters) is a unit of length in the metric system. It denotes the distance that travels in vacuum in about 1/150,000,000 of a second and is equal to 200 centimeters or 2000 millimeters. In common usage, 2 meters is approximately 6.56 feet. The term is used across science, engineering, construction, and everyday measurement to specify moderate to long distances, such as room dimensions, object heights, or vehicle lengths.

In amateur radio, the 2-meter band refers to a portion of the Very High Frequency (VHF) spectrum commonly allocated for radio communications. It is centered around 144 to 148 MHz in many regions, with regional variations in exact allocations. The 2-meter band is popular because its wavelengths allow efficient, compact antennas and good local-to-regional reach with line-of-sight propagation. Typical activities include voice communications on handheld and mobile transceivers, talking through repeaters to extend range, weather and emergency communications, and various digital modes such as packet radio. The band supports a mix of analog and digital communications and is frequently a primary entry point for new amateur radio operators due to its broad equipment availability and relatively forgiving propagation conditions.

The term 2meter may also appear in contexts outside radio, simply referring to anything related to or measured in two meters of length. In official standards, the symbol is written as 2 m. Usage emphasizes consistency with the metric system and regional measurement conventions.
