ton-force
{{Short description|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.All calculations on this page assume the following definition of standard gravity, g0.
:g0 = {{val|9.80665|u=m/s2}} The precise definition depends on the definition of ton used.
Tonne-force
The tonne-force (tf or tf)The tonne-force, also known as the metric ton force, is equivalent to the megagram-force (Mgf or Mgf) and the megapond (Mp). is equal to the weight of one (metric) tonne.
