DimensionalCombinations

DimensionalCombinations[{pq1, pq2, ...}] returns possible combinations of physical quantities that are dimensionless.

DimensionalCombinations[{pq1, pq2, ...}, dim] returns combinations matching dimensions of dim.

Examples

Find dimensionless combinations:

DimensionalCombinations[{Quantity["Length"], Quantity["Time"], Quantity["Speed"]}]

Match specific dimensions:

DimensionalCombinations[{Quantity["Mass"], Quantity["Speed"]}, Quantity["Energy"]]
