Conversion Formula
kN = p × 9.806650000e-6
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.
About Kilonewtons
A kilonewton (kN) is 1,000 N - the standard force unit for structural engineering outside North America. A 70 kg person exerts ~0.687 kN; a heavy goods vehicle axle 100-130 kN; a loaded Boeing 747 on its landing gear ~2,800 kN. Eurocode and BS EN structural codes express beam loads and foundation reactions in kN and bending moments in kN·m. Universal testing machines for materials testing are rated 10-10,000 kN. Prestressed concrete tendons are stressed to 100-250 kN each. 1 kN = 1,000 N = 224.81 lbf = 101.97 kgf.
