About Pound-Force
The pound-force (lbf) is the gravitational force on 1 lb-mass under standard gravity - exactly 4.4482216152605 N. It dominates US structural, mechanical, and aerospace engineering: AISC and ACI structural codes use lbf and kips (1 kip = 1,000 lbf); tire pressure 'psi' means lbf/in²; engine torque in lb·ft. Aircraft thrust is quoted in lbf: the GE90-115B (Boeing 777) produces 115,300 lbf = 513 kN. Spring rates, fastener torques, and load cell calibrations across North America are in lbf. 1 lbf = 4.44822 N = 16 ozf = 32.174 pdl.
About Pond
The pond (p), also called gram-force (gf), is the gravitational force on 1 g under standard gravity - exactly 9.80665 × 10⁻³ N. It belongs to the metric gravitational technical system that dominated continental European engineering before SI. One thousand ponds = one kilopond (kp) = kilogram-force (kgf). Laboratory balances reading in grams technically measure pond, not mass. Older Mettler and Sartorius balance specs quote spring forces in pond. Pre-SI textile tensile strength was expressed in pond/tex. 1 p = 1 gf = 9.80665 mN = 0.001 kgf.
