Ton-Force (Long) [tonf (UK)]


The long ton-force (also called the UK ton-force) is a unit of force based on the long ton, traditionally used in the United Kingdom.



  • A long ton equals 2,240 pounds (lbs).



  • The long ton-force is the force exerted by a long ton mass under standard gravity.



  • Mathematically:



1 tonf (UK)=2,240 lbs×9.80665 m/s29,964.02 newtons1 \text{ tonf (UK)} = 2,240 \text{ lbs} \times 9.80665 \text{ m/s}^2 \approx 9,964.02 \text{ newtons}

  • It is used in engineering and industries where the long ton is the standard measure of mass.



  • This unit is larger than the short ton-force and differs from the metric ton-force.


Centinewton [cN]


Centinewton is a unit of force in the International System of Units (SI).



  • 1 centinewton (cN) equals 10210^{-2} newtons (0.01 newton).



  • It is used to measure very small forces, useful in precision engineering, material testing, and small-scale physics experiments.



  • To put it in perspective:



1 cN=0.01 N1 \text{ cN} = 0.01 \text{ N}

Centinewtons allow convenient expression of forces smaller than decinewtons but larger than millinewtons.
