Ton-force
(Redirected from Short ton force)
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
[edit]The tonne-force (tf or tf)[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
[edit]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
[edit]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
[edit]- ^ 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 Mgf) and the megapond (Mp).

1 pound = 0.45359237 kg ∴ 1 tonne-force = 1000/0.45359237 lbf ≈ 2204.62262184887 lbf - ^
1 long ton = 1.0160469088 t ∴ 1 tonne-force = 1/1.0160469088 long tons-force ≈ 0.98420652761106 long tons-force - ^
1 short ton = 0.90718474 t ∴ 1 tonne-force = 1/0.90718474 short tons-force ≈ 1.1023113109244 short tons-force - ^
1 pdl = 0.138254954376 N ∴ 1 tonne-force = 9806.65/0.138254954376 pdl ≈ 70931.635283968 pdl - ^
1 long ton-force = 2240/2000 short tons-force = 1.12 short tons-force - ^
g0 = 9.80665/0.3048 ft/s2 ∴ 1 long ton-force = 2240 lb × 9.80665/0.3048 ft/s2 = 27458620/381 pdl ≈ 72069.868766404 pdl - ^
1 short ton-force = 2000/2240 long tons-force = 25/28 long tons-force ≈ 0.892857143 long tons-force - ^
1 short ton-force = 2000 lb × 9.80665/0.3048 ft/s2 = 24516625/381 pdl ≈ 64348.09711 pdl
