Convert Metric Ton-Force to Kilogram-Force
Convert Metric Ton-Force (tf) to Kilogram-Force (kgf) instantly and accurately.
Conversion Formula
kgf = tf × 1000
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 Kilogram-Force
The kilogram-force (kgf), also called the kilopond (kp), is the gravitational force on 1 kg under standard gravity - exactly 9.80665 N. It was the primary force unit in continental European engineering before SI. ISO 1000 (1973) and EU Directive 80/181/EEC deprecated it in favour of the newton. Spring and bathroom scales reading in 'kg' technically measure kgf. Older DIN and JIS materials standards give tensile strength in kgf/mm² (× 9.80665 = MPa). Hydraulic cylinder ratings in legacy European machinery use kgf or tonne-force. 1 kgf = 9.80665 N = 2.20462 lbf.
