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 Feet of Water measurement unit is most often used to measure depth of a liquid, such as in a tank or a large body of water. The temperature must be specified to make the measurement uniform. The standard measurement temperature of the water is 4 degrees Celsius.
