About these units
Quarter (US) (qr (US))
The US quarter equals 25 pounds, serving as a smaller commercial subdivision of the hundredweight. It was used for pricing agricultural goods, livestock feed, and some industrial materials. Its convenience arises from the fact that four quarters make a hundredweight, simplifying scaling between small and medium quantities. Today it is mostly of historical interest, but agricultural economists still encounter it when analyzing archival data.
Kilogram-force Second/Meter (kgf·s²/m)
This unusual unit represents a derived inertial mass-like quantity used in older engineering contexts based on gravitational force units rather than pure mass. One kilogram-force is the force exerted by gravity on a mass of one kilogram under standard gravity. When combined with s²/m, this creates a pseudo-mass unit used in engineering calculations involving dynamic systems. Although rarely used today, kgf·s²/m illustrates a transitional phase in engineering where gravitational and inertial concepts were intermixed before SI units standardized distinctions between mass and force.
