About these units
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.
Quarter (UK) (qr (UK))
The UK quarter, equal to 28 pounds, corresponds to 1/4 of a UK hundredweight. Historically used in grain trade, wool markets, and taxation, it reflects the older English approach to structuring weights around the stone. Its direct link to the long hundredweight made it easy for merchants to calculate loads and price goods. While obsolete today, the UK quarter remains important for historians reconstructing traditional British commerce and agricultural economies.
