Ton-force Knowpia

A ton-force is one of various units of force defined as the weight of one ton due to standard gravity.^{[note 1]} The precise definition depends on the definition of ton used.

Tonne-force

The tonne-force (tf or t_f)^{[note 2]} is equal to the weight of one tonne.

one tonne-force	= 1000 kilograms-force (kgf)
	= 9.80665 kilonewtons (kN)
	≈ 2204.623 pounds-force (lbf)^{[note 3]}
	≈ 0.9842065 long tons-force^{[note 4]}
	≈ 1.1023113 short tons-force^{[note 5]}
	≈ 70931.64 poundals (pdl)^{[note 6]}

Long ton-force

The long ton-force is equal to the weight of one long ton.

one long ton-force	= 2240 lbf
	= 1016.0469088 kgf
	= 9.96401641818352 kN
	= 1.12 short tons-force^{[note 7]}
	≈ 72069.87 pdl^{[note 8]}

Short ton-force

The short ton-force is equal to the weight of one short ton.

one short ton-force	= 2000 lbf
	= 907.18474 kgf
	= 8.896443230521 kN
	≈ 0.892857 long tons-force^{[note 9]}
	≈ 64348.10 pdl^{[note 10]}

Notes

^ All calculations on this page assume the following definition of standard gravity, g₀.
g₀ = 9.80665 m/s²
^ The tonne-force, also known as the metric tone force, is equivalent to the megagram-force (Mgf or Mg_f) and the megapond (Mp).
