About these units
Gerah (Biblical Hebrew) (gerah)
A gerah, approximately 0.57 grams, is the smallest unit in the Hebrew weight system. 1 shekel = 20 gerahs Gerahs were used for minute quantities of precious metals or spices for ritual purposes. Biblical texts refer to gerahs in the context of sanctuary offerings and priestly duties. The gerah illustrates the fine-grained precision required for temple rituals and daily commerce in the ancient Near East.
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.
