A dyne (dyn) is the unit of force in the centimeter-gram-second (cgs) system. It is the force which gives an acceleration of 1 cm/s² to a body of 1 g (=10⁻³ kg) mass. In SI units, one dyne = 10⁻⁵ N (newton), because

${\displaystyle 1\;\mathrm {dyn} =1\;\mathrm {g} \;{\frac {1\;\mathrm {cm} }{\mathrm {s} ^{2}}}=10^{-3}\;\mathrm {kg} \;{\frac {10^{-2}\;\mathrm {m} }{\mathrm {s} ^{2}}}=10^{-5}\;{\frac {\mathrm {kg} \cdot \mathrm {m} }{\mathrm {s} ^{2}}}=10^{-5}\;\mathrm {N} .}$

The name was first proposed in 1873 by the British Association for the Advancement of Science.
