? Could't tell if that was sarcastic.
To measure alcohol levels in beer you determine the specific gravity using a tool called a hydrometer.
Beer is easy to measure because it is a homogeneous mixture. The alcohol level is the same at the bottom of the barrel as it is at the top.
To measure cannabis they use gas chromatography and compare relative substances. The problem is that a bud is not homogeneous like a bottle of beer. There could be more THC glands in one spot and less in another. All you could get is an approximate range.
Hope that helps.
