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. 


Planck Mass

The Planck mass (mP) is the natural unit of mass in the Planck system of units, defined as √(ℏc/G) ≈ 2.176 × 10⁻⁸ kg, where ℏ is the reduced Planck constant, c is the speed of light, and G is the gravitational constant. It represents the scale at which quantum gravitational effects are expected to become significant. The Planck mass is roughly the mass of a flea egg and serves as a fundamental reference scale in theoretical physics and quantum gravity research.
