Kilogram

The kilogram (also kilogramme) is the base unit of mass in the metric system, formally the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering, and commerce worldwide, and is often simply called a kilo in everyday speech. 


Attogram

The attogram (ag) is a unit of mass equal to 10⁻¹⁸ grams, derived by applying the SI prefix atto- to the gram. It represents one of the smallest practically measurable masses, employed in cutting-edge nanotechnology and nanomechanical resonator experiments. Researchers have used nanoscale devices to detect masses as small as a few attograms.
