Using three-value logic in the theory of dimensionality of physical values

The use of calculation of statements of three-value Bochvar logic in the theory of dimensionality of physical values is examined. A "draft" of the theory of dimensionalities, whose basic postulate is the formula which symbolically expresses the statement: "If the equality V = W makes sense, then the equality [VJ] = [WJ] of the [VJ] and [WJ] dimensionalities of the physical values V and W is true," is presented. The question about the dimensionalities of physical values in the Gauss and ISU (International System of Units) is briefly examined.
