About these units
Decigram (dg)
A decigram equals 1/10 of a gram and appears in older scientific literature, pharmaceutical compounding, and some food chemistry applications. Today, milligrams and grams are more common, but decigrams still offer practical value when describing masses that naturally fall between these scales, such as certain supplements or cosmetic ingredients. The decigram remains a reminder of the metric system's logical progression, offering users a consistent, scalable set of units.
Planck Mass (mₕ)
The Planck mass, approximately 2.176434 × 10⁻⁸ kilograms, occupies a unique position in theoretical physics. Unlike particle masses, it is derived entirely from fundamental constants—Planck's constant, Newton's gravitational constant, and the speed of light. The Planck mass represents a mass scale where quantum mechanical and gravitational effects become comparable. Although enormous relative to subatomic particles (roughly the mass of a dust grain), it is considered "natural" in that it emerges from pure physics rather than empirical observation. In theoretical studies of black holes, quantum gravity, string theory, and early-universe cosmology, the Planck mass marks a boundary beyond which existing models require unification. It is a conceptual rather than practical unit, yet it provides a profound insight into the structure of physical law.
