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.
 • Maple knows the units of force listed in the following table.

 Name Symbols Context Alternate Spellings Prefixes newton N SI * newtons SI gramforce gf SI * gramforces SI pond standard * ponds sthene standard * sthenes SI dyne dyn standard * dynes SI ounceforce ozf standard * ounceforces poundforce lbf standard * poundforces tonforce tonf standard * tonforces kipf standard * kipfs poundal standard * poundals planck_force planck * planck_forces

 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.
