Something's gotta give... for that to work the Imperial teaspoon has to be bigger than the US teaspoon. Clearly these functional tools are internally consistent but not consistent between types. As far as I know there are no US or Imperial standards on par with the standard kilogram or standard meter (or now, the atomic standards that are even more precise for distance) that are agreed upon throughout the scientific world. The other systems are just conversion factors relative to the metric standards.
