Units of Force

Description

• 

Force has the dimension length mass per time squared. The SI unit of force is the newton, which is defined as a kilogram meter per second squared.

•

An asterisk ( * ) indicates the default context, an at sign (@) indicates an abbreviation, and under the prefixes column, SI indicates that the unit takes all SI prefixes, IEC indicates that the unit takes IEC prefixes, and SI+ and SI- indicate that the unit takes only positive and negative SI prefixes, respectively.  Refer to a unit in the Units package by indexing the name or symbol with the context, for example, newton[SI] or lbf[standard]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, newton or lbf.

  

 

  

The units of force are defined as follows.

  

A gramforce is defined as the force of gravity on a gram, that is, acceleration_of_free_fall*gram.

  

A pond is another term for the gramforce.

  

A dyne is defined as a gram centimeter per second squared.

  

A sthene is defined as a tonne meter per second squared.

  

An ounceforce is defined as the force of gravity on an avoirdupois ounce, that is, acceleration_of_free_fall*ounce.

  

A poundforce is defined as the force of gravity on an avoirdupois pound, that is, acceleration_of_free_fall*pound.

  

A tonforce is defined as the force of gravity on a short ton, that is, acceleration_of_free_fall*ton.

  

A kipf is defined as 1000 poundforces.

  

A poundal is defined as an avoirdupois pound international foot per second squared.

  

A planck force is defined as a planck length times planck mass per planck time cubed.
