The `"dyn/""cm""^2` unit is often used to measure pressures. This is a very small pressure unit and is used in measurement of shear stresses. The Dyne per Square Centimeter is derived from the CGS unit of force. 1 Dyne is equal to 1 gram accelerated 1 centimeter per second squared. The at unit is a non-SI unit. The Technical Atmosphere unit of pressure equals a one kilogram-force per square centimeter.
