Nano-droids with a length of 1.5 nanometers shown at 200x magnification
Nanometer signified a measurement unit for length, employed when quantifying extremely diminutive objects. A prime example includes nano-droids from the NM-K reconstitutor, which possessed a length of 1.5 nanometers. Objects of such minute dimensions, approximating a single nanometer, approached near invisibility.
