About these units
Exagram (Eg)
An exagram, equal to 10¹⁵ kilograms, is used to describe masses of planets, moons, and extremely large terrestrial reservoirs (e.g., total mass of Earth's atmosphere ≈ 5 Eg). Because of its enormous scale, the exagram rarely appears outside astrophysics or large-scale geophysics. When used, however, it provides a powerful sense of magnitude—allowing scientists to describe Earth systems at the grandest scales with simple, comprehensible numbers.
Scruple (Apothecary) (s.ap)
The scruple is an old apothecary unit equal to 20 grains or 1.2959782 grams, originating in ancient Greek and Roman medicine. Apothecaries used scruples for compounding herbal remedies, powders, and tinctures long before standardized metric systems were adopted. Its size made it ideal for preparing early pharmaceuticals where doses needed to be accurate but not excessively granular. Over centuries, the scruple appeared in medical recipes, early scientific writings, and even medieval charms and remedies. Although obsolete today, replaced by milligrams and grams, the scruple is vital for historians studying early medical texts, pharmacy records, and classical-era scientific practices.
