tonne-force
Forceexact by definition
The tonne-force is the weight of one metric tonne under standard gravity, exactly 9806.65 newtons, or 9.80665 kN. European and Asian press ratings, crane capacities and jack sizes are quoted this way.
Watch out: A "100 ton press" needs its ton identified. 100 tonne-force is 981 kN, 100 US short ton-force is 890 kN, and 100 long ton-force is 996 kN, a spread of 12 percent on the same nameplate number.
