Ton-force

Unit of force defined as the weight of one ton

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.

Long ton-force

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

Short ton-force

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

Notes

1. All calculations on this page assume the following definition of standard gravity, g₀.

   g₀ = 9.80665 m/s²

2. The tonne-force, also known as the metric tone force, is equivalent to the megagram-force (Mgf or Mg_f) and the megapond (Mp).
