About these units
Drachma (Biblical Greek) (drachma)
The drachma, roughly 4.3 grams, served as the principal Greek silver unit for centuries. Both a mass and a monetary unit, the drachma appears extensively in ancient writings, from philosophy to commerce to biblical passages. The term originates from "a handful," linking the weight to early barter practices. Over time, it became a symbol of civic identity—different city-states minted distinct drachmas with unique iconography. Its influence survives in the name of Greece's former national currency, the drachma, reinforcing its cultural legacy.
Pound-force Square Second/Foot (lbf·s²/ft)
This unit is part of the British Gravitational System, where mass is defined from force rather than the other way around. It can be interpreted as an inertial mass unit, since applying 1 pound-force to it would produce an acceleration of 1 foot per second squared. Historically, before the SI system clarified the distinction between force and mass, engineering fields often used mixed systems where pounds could represent either force (lbf) or mass (lbm). The unit lbf·s²/ft was introduced to straighten out these ambiguities in dynamic calculations such as impact forces, mechanical oscillations, and safety load computations. Today, the unit survives mostly in engineering textbooks, legacy calculations, and historical documentation. It demonstrates how complex and inconsistent measurement systems once were, and why global scientific communities moved toward SI clarity.
