Dynes}} In [[physics]], the '''dyne''' (symbol "dyn", from Greek δύναμις (''dynamis'') meaning power, force) is a [[Units of measurement|unit]] of [[Force (physics)|force]] specified in the ''[[Centimetre gram second system of units|centimetre-gram-second]]'' (CGS) [[system of units]], a predecessor of the modern [[International System of Units|SI]]. One dyne is equal to exactly 10 micro[[newton]]s. 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". ; 1 dyn = 1 g·cm/s² = 10<sup>−5</sup> kg·m/s² = 10 µN The '''dyne per centimetre''' is the unit usually associated with measuring [[surface tension]]. For example, the surface tension of distilled water is 72 dyn/cm at 25°C (77°F).<ref>http://www.dow.com/PublishedLiterature/dh_00e5/09002f13800e5fdb.pdf?filepath=/PublishToInternet/InternetDOWCOM/surfactants/pdfs/noreg/119-01514.pdf&fromPage=BasicSearch</ref> {{Units of force}} {{Wikisource1914NSRW|Dyne}} [[Category:Centimetre gram second system of units]] [[ast:Dina]] [[de:Dyn]] [[es:Dina]] [[eo:Dino]] [[eu:Dina]] [[fr:Dyne]] [[ko:다인]] [[it:Dyne]] [[he:דיין (מידה)]] [[nl:Dyne]] [[ja:ダイン]] [[pl:Dyna]] [[pt:Dina]] [[ru:Дина (единица измерения)]] [[sl:Dina]] [[fi:Dyne]] [[tr:Dyn]] [[uk:Дина]] [[zh:达因]]
