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

Electron Mass (Rest)

The rest mass of an electron is the intrinsic mass of an electron when it is at rest (not moving relative to an observer).

Its value is approximately 9.109 × 10⁻³¹ kilograms (or about 0.511 MeV/c² in energy units).

This tiny mass is fundamental to atomic and particle physics, influencing how electrons behave in atoms and electric currents.

Summary:

Rest mass ≈ 9.109 × 10⁻³¹ kg
Equivalent to about 0.511 MeV/c²
Fundamental property of the electron in physics
