In physics, the dyne is a unit of force specified in the centimetre-gram-second (cgs) system of units, symbol "dyn". One dyne is equal to exactly 10-5 newtons. Further, the dyne can be defined as "the force required to accelerate a mass of one gram at a rate of one centimetre per second squared." Since antiquity, people have tried to understand the behavior of matter: why unsupported objects drop to the ground, why different materials have different properties, and so forth. ... The word unit means any of several things: Unit of measurement or physical unit, a fundamental quantity of measurement in science or engineering. ... In physics, a net force acting on a body causes that body to accelerate; that is, to change its velocity. ... CGS is an acronym for centimetre-gram-second. ... In physics and metrology, units are standards for measurement of physical quantities that need clear definitions to be useful. ... The newton (symbol: N) is the SI unit of force. ... Mass is a property of physical objects that, roughly speaking, measures the amount of matter they contain. ... The gram or gramme, symbol g, is a unit of mass, and is defined as one one-thousandth of the SI base unit kilogram (i. ... The metre, or meter (symbol: m) is the SI base unit of length. ... The second (symbol s) is a unit for time, and one of seven SI base units. ...

1 N = 1 kg·m/s² = 105 dyn ≈ 0.10197 kp ≈ 0.22481 lbf ≈ 7.2330 pdl
1 dyn = 10−5 N = 1 g·cm/s² ≈ 1.0197×10−6 kp ≈ 2.2481×10−6 lbf ≈ 7.2330×10−5 pdl
1 kp = 9.80665 N = 980665 dyn = gn·(1 kg) ≈ 2.2046 lbf ≈ 70.932 pdl
1 lbf ≈ 4.448222 N ≈ 444822 dyn ≈ 0.45359 kp = gn·(1 lb) ≈ 32.174 pdl
1 pdl ≈ 0.138255 N ≈ 13825 dyn ≈ 0.014098 kp ≈ 0.031081 lbf = 1 lb·ft/s²
The values for the pound-force are calculated using the same value for the standard acceleration of
gravity gn which is official for defining the kilopond (a.k.a. kilogram-force), something which is not
required. Other values such as gn = 32.16 ft/s² are also used.

F. f. Greek δυναμις (dunamis) power, force. The newton (symbol: N) is the SI unit of force. ... The International System of Units (abbreviated SI from the French phrase, SystÃ¨me International dUnitÃ©s) is the most widely used system of units. ... The deprecated unit kilogram-force (kgf) or kilopond (kp) is the force exerted by one kilogram of mass in standard Earth gravity (defined as exactly 9. ... The pound-force is a non-SI unit of force or weight (properly abbreviated lbf or lbf). The pound-force is equal to a mass of one pound multiplied by the standard acceleration due to gravity on Earth (which is defined as exactly 9. ... The poundal is a non-SI unit of force. ... g (also gee, g-force or g-load) is a non-SI unit of acceleration defined as exactly 9. ... The pound is the name of a number of units of mass or weight, all in the range of 300 to 600 grams. ... A foot (plural: feet) is a non-SI unit of distance or length, measuring around a third of a metre. ... Results from FactBites:
