There are many instruments used to measure length including rulers, tape measures, micrometers, gauges and vernier calipers. There are also instruments that make use of scientific principles to deduce length where it may not be directly measured. Measuring lengths accurately has been a driving force

Some commonly used density measuring devices include hydrometers, aerometers, pycnometers, density kits and digital density meters. The density of an object can be manually computed by dividing its mass by its volume, which is mathematically represented by the formula d = m/v, where "d" denotes dens
