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.
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.
