Dyne

History

The name dyne was first proposed as a CGS unit of force in 1873 by a Committee of the British Association for the Advancement of Science.{{cite conference |editor-first= Professor |editor-last = Everett |access-date= 8 April 2012}}

Definition

The dyne is defined as "the force required to accelerate a mass of one gram at a rate of one centimetre per second squared". An equivalent definition of the dyne is "that force which, acting for one second, will produce a change of velocity of one centimetre per second in a mass of one gram".

One dyne is equal to 10 micronewtons, 10−5 N or to 10 nsn (nanosthenes) in the old metre–tonne–second system of units.

• 1 dyn = 1 g⋅cm/s2 = 10−5 kg⋅m/s2 = 10−5 N
• 1 N = 1 kg⋅m/s2 = 105 g⋅cm/s2 = 105 dyn

Use

The dyne per centimetre is a unit traditionally used to measure surface tension. For example, the surface tension of distilled water is 71.99 dyn/cm at 25 °C (77 °F).{{cite book | editor = Haynes, W.M. | editor2=Lide, D.
