Conversion Formula
lbf = tf × 2204.622622
About Metric Ton-Force
One metric tonne-force (tf) is the gravitational force on 1,000 kg under standard gravity - exactly 9,806.65 N = 9.80665 kN. It dominates international heavy engineering: crane hook capacities are rated in tf (a '50-tonne crane' lifts 50 tf = 490.3 kN); ship mooring lines, anchor holding power, and cargo lashing per IMO standards are in tf; hydraulic presses for metal extrusion and stamping in Europe and Asia are rated in tf. ISO 7531 lifting-gear working load limits (WLL) use tf. 1 tf = 1,000 kgf = 9,806.65 N = 2,204.6 lbf.
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.
