Planck Mass
The Planck mass is a fundamental physical constant in theoretical physics, representing a natural unit of mass based on fundamental constants: the speed of light, gravitational constant, and Planck’s constant.
Its value is approximately 2.18 × 10⁻⁸ kilograms (about 22 micrograms).
The Planck mass is significant in quantum gravity and string theory, marking a scale where quantum effects of gravity become strong and classical physics breaks down.
Summary:
Approximately 2.18 × 10⁻⁸ kg (22 micrograms)
Derived from fundamental physical constants
Important in quantum gravity and theoretical physics
Pennyweight (pwt)
The pennyweight (pwt) is a unit of mass traditionally used in the precious metals and jewelry industries. It is part of the troy and apothecary weight systems.
One pennyweight equals 1/20 of a troy ounce, or 24 grains, which is approximately 1.555 grams.
Pennyweights are commonly used to measure gold, silver, and gemstones, offering a precise small-scale weight unit for valuable materials.
Summary:
1 pennyweight = 1/20 troy ounce ≈ 1.555 grams
Used mainly in precious metals and jewelry
Part of the troy weight system
