Editing Force (section)

== Units ==
The [[SI]] unit of force is the [[Newton (unit)|newton]] (symbol N), which is the force required to accelerate a one kilogram mass at a rate of one meter per second squared, or kg·m·s<sup>−2</sup>.The corresponding [[CGS]] unit is the [[dyne]], the force required to accelerate a one gram mass by one centimeter per second squared, or g·cm·s<sup>−2</sup>. A newton is thus equal to 100,000&nbsp;dynes.<ref name= metric_units>{{cite book |first1=Cornelius |last1=Wandmacher |first2=Arnold |last2=Johnson |title=Metric Units in Engineering |page=[https://archive.org/details/metricunitsineng0000wand/page/15 15] |year=1995 |publisher=ASCE Publications |isbn=978-0-7844-0070-8 |url=https://archive.org/details/metricunitsineng0000wand/page/15 }}</ref>

The gravitational [[foot-pound-second]] [[English unit]] of force is the [[pound-force]] (lbf), defined as the force exerted by gravity on a [[pound-mass]] in the [[Standard gravity|standard gravitational]] field of 9.80665&nbsp;m·s<sup>−2</sup>.<ref name=metric_units/> The pound-force provides an alternative unit of mass: one [[slug (unit)|slug]] is the mass that will accelerate by one foot per second squared when acted on by one pound-force.<ref name=metric_units/> An alternative unit of force in a different foot–pound–second system, the absolute fps system, is the [[poundal]], defined as the force required to accelerate a one-pound mass at a rate of one foot per second squared.<ref name=metric_units/>

The pound-force has a metric counterpart, less commonly used than the newton: the [[kilogram-force]] (kgf) (sometimes kilopond), is the force exerted by standard gravity on one kilogram of mass. The kilogram-force leads to an alternate, but rarely used unit of mass: the [[metric slug]] (sometimes mug or hyl) is that mass that accelerates at 1&nbsp;m·s<sup>−2</sup> when subjected to a force of 1&nbsp;kgf. The kilogram-force is not a part of the modern SI system, and is generally deprecated, sometimes used for expressing aircraft weight, jet thrust, bicycle spoke tension, torque wrench settings and engine output torque.<ref name= metric_units/>
