The conversion from milligrams (mg) of tetrahydrocannabinol (THC) to percentage (%) is a calculation used to determine the concentration of THC in a given product, such as cannabis flower, edibles, or concentrates. This conversion expresses the amount of THC present relative to the total weight of the product. For instance, knowing the milligram content of THC in an edible and the total weight of the edible allows one to calculate the percentage of THC present.
Understanding the THC concentration is vital for consumers to accurately dose cannabis products and avoid unintended effects. Accurate dosage information is also crucial for regulatory compliance in jurisdictions where cannabis use is legal. Historically, THC content was often estimated, but with increasing legalization and standardization, precise measurements and conversions have become increasingly important for both consumers and producers.
