If a variable is defined using math non-linear functions on other variables that are defined with units, evaluated values may seem unexpected. For example, variable g is assigned a value of 8 mil. If another variable is introduced using linear math function of variable g, for example Linear_math, which is assigned a value of 2*g, will have an evaluated value of 16 mil. However, if we use non-linear math function, for example sqrt(g*g), the evaluated value will be a unitless value of 0.0002032 which may be confusing for a user (see Fig.1).
