Cannabis Potency Calculator [For Flower]

This Cannabis Potency Calculator is designed to estimate the total cannabinoid content in your cannabis flower, both before and after accounting for loss due to burn-off. This is particularly useful for understanding the potency of your cannabis products and making informed decisions about consumption, especially when using different methods such as joints, pipes, vaporizers, or bongs.

How to Use:

  1. Enter the Cannabinoid Percentages (%): Input the THC, CBD, and CBG concentration of your cannabis flower. This is typically provided as a percentage on the product label or from lab test results.

  2. Enter the Flower Weight (g): Input the weight of your cannabis flower in grams.

  3. Select the Consumption Method: Choose your method of consumption from the options provided (Joint, Pipe, Vaporizer, Bong). Each method has an estimated average loss rate due to burn-off. 50% for Joint/Pipe/Bong and 20% for Vaporizers due to their efficiency.

  4. Calculate: Click the ‘Calculate’ button. The calculator will compute the total cannabinoid content in milligrams (mg) and then adjust this amount based on the selected consumption method’s average loss rate.


  • The calculator displays the total cannabinoid content of your cannabis flower in milligrams (mg).
  • It also provides an adjusted cannabinoid content, which estimates the amount after factoring in the loss due to the chosen consumption method.

Accuracy Disclaimer: Please note that these calculations provide an approximation. Actual THC intake can vary based on several factors, including the efficiency of the consumption method and individual usage habits. The estimated loss rates for each method are averages and may not reflect the specific rate of THC loss in every situation.
