Scruple (Apothecary)

A scruple (s.ap) is an old unit of weight used in apothecary measurements, equivalent to 1.3 grains or approximately 1.3 grams.

History/Origin

The scruple originated in ancient Greece and was adopted into Roman and medieval European apothecary systems. It was historically used for measuring small quantities of medicinal substances and drugs.

Current Use

Today, the scruple is largely obsolete and replaced by metric units, but it is still referenced in historical contexts and traditional apothecary practices.


Planck Mass

The Planck mass (m_P) is a fundamental physical constant representing a mass scale derived from natural units, approximately 2.176 Γ— 10^-8 kilograms.

History/Origin

Introduced by Max Planck in 1899 as part of his system of natural units, the Planck mass emerged from combining fundamental constants to define a universal mass scale in theoretical physics.

Current Use

The Planck mass is primarily used in theoretical physics, especially in quantum gravity and high-energy physics, to express natural units and scale phenomena near the Planck scale.
