Fun Facts

Planck Mass (~2.18e-8 kg – quantum quirk)
At roughly 22 micrograms, the Planck mass is the universe’s tiniest weight unit – so minuscule you’d need quantum tweezers to pick one up.

About Mass & Weight

Learn about the various mass and weight measurement systems used around the world

Historical Context

Mass and weight units have evolved differently across civilizations. The metric system standardized measurements with the kilogram, while the imperial system uses pounds and ounces. Specialized units like carats for gemstones and troy weights for precious metals serve specific commercial purposes.

Modern Standards

Today, the kilogram is the SI base unit for mass, defined by the Planck constant. While most countries use the metric system, the US still commonly uses pounds and ounces. In scientific contexts, grams and kilograms are universal standards regardless of location.
