Radiation exposure is measured in becquerels, grays, and sieverts, for the decay rate, absolute absorbed quantity of radiation, and relative effect on human tissues.
Piquancy exposure is measured only in scoville-heat-units, which is the spiciness equivalent of the sievert. Clearly, piquancy is in need of at least one additional unit that can abstract away the variations in mammalian tongues. That number, in combination with your personal taste profile, would allow you to predict the perceived spiciness of any given dish when you eat it.
You would just need to objectively measure the concentrations of capsaicinoids, and their TRPV1-activating analogs, put those into a spreadsheet with your own numbers, and determine how piquant something would be in scoville-heat-units when you, specifically, eat it.
