  2. Ton-force - Wikipedia

    en.wikipedia.org/wiki/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 ...

  3. Equations for a falling body - Wikipedia

    en.wikipedia.org/wiki/Equations_for_a_falling_body

    A set of equations describing the trajectories of objects subject to a constant gravitational force under normal Earth-bound conditions.Assuming constant acceleration g due to Earth's gravity, Newton's law of universal gravitation simplifies to F = mg, where F is the force exerted on a mass m by the Earth's gravitational field of strength g.

    en.wikipedia.org/wiki/List_of_conversion_factors

    See Weight for detail of mass/weight distinction and conversion. Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound.

  5. Short ton - Wikipedia

    en.wikipedia.org/wiki/Short_ton

    The short ton (abbreviation tn [1]) is a measurement unit equal to 2,000 pounds (907.18 kg). It is commonly used in the United States , where it is known simply as a ton; [ 1 ] however, the term is ambiguous, the single word " ton " being variously used for short, long , and metric tons.

  6. English Engineering Units - Wikipedia

    en.wikipedia.org/wiki/English_Engineering_Units

    Units for other physical quantities are derived from this set as needed. In English Engineering Units, the pound-mass and the pound-force are distinct base units, and Newton's Second Law of Motion takes the form = where is the acceleration in ft/s 2 and g c = 32.174 lb·ft/(lbf·s 2).

  7. Traction (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Traction_(mechanics)

    A 70-ton M1A2 would sink to the point of high centering if it used round tires. The tracks spread the 70 tons over a much larger area of contact than tires would and allow the tank to travel over much softer land. In some applications, there is a complicated set of trade-offs in choosing materials.

  8. Conversion of units - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_units

    The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...

  9. Ton - Wikipedia

    en.wikipedia.org/wiki/Ton

    The water ton is used chiefly in Great Britain, in statistics dealing with petroleum products, and is defined as 224 imperial gallons (35.96 cu ft; 1.018 m 3), [22] the volume occupied by 1 long ton (2,240 lb; 1,016 kg) of water under the conditions that define the imperial gallon.
