About Weight Units
Weight is a measure of the force of gravity acting on an object. The SI unit of mass is the kilogram (kg). Common metric prefixes include kilo- (×1000), milli- (×0.001), and micro- (×0.000001). While metric units are used globally in science and most countries, imperial units like pounds and ounces remain common in the US and a few other regions.

The atomic mass unit (AMU) is an incredibly small unit of mass, equal to 1/12 of the mass of a carbon-12 atom. It's primarily used in atomic and molecular physics. One gram contains approximately 6.022 × 10²³ AMU, a number known as Avogadro's constant. This unit helps scientists work with the masses of individual atoms and molecules.
