Convert Short Ton-Force to Metric Ton-Force
Convert Short Ton-Force (tf (US)) to Metric Ton-Force (tf) instantly and accurately.
Conversion Formula
tf = tf (US) × 0.90718474
About Short Ton-Force
One short ton-force is the gravitational force on a US short ton (2,000 lb) - exactly 2,000 lbf ≈ 8,896 N. It is used in heavy US industry for hydraulic press force ratings, forging press capacities, crane lift ratings, and bulldozer drawbar pull. US rigging and lifting equipment is rated in short tons. Caution: short ton-force (8,896 N) vs metric tonne-force (9,807 N) vs long ton-force (9,964 N) introduces up to 12% ambiguity when 'ton capacity' is unqualified - a critical safety distinction. 1 short tf = 2,000 lbf = 2 kip = 8,896.44 N.
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.
