A slug is considered a garden pest and a curiosity to many. This article will give basic slug information and description, the life cycle of slugs, different methods of slug control in gardens and around homes.
Systems of measure either define mass and derive weights or define a base weight and derive a mass unit. A slug is defined as the mass that is accelerated by 1 ft/s when a force of one pound (lbf) is exerted on it. One slug has a mass of 32.174049 lb or 14.593 903 kg based on standard gravity , the international foot , and the avoirdupois pound . At the surface of the Earth, an object with a mass of 1 slug exerts a force downward (definition of weight) of approximately 32.2 lbf or 143 N . History The slug is part of a subset of units known as the gravitational FPS system , one of several such specialized systems of mechanical units developed in the late 19th and the 20th century. Geepound was another name for this unit in early literature. The name slug was coined before 1900 by British physicist Arthur Mason Worth Express yourself.
