In the US, weed weights come in a variety of measurements. And the smallest of those measurements is the gram. But why do we weigh some weed amounts in grams and other in ounces?
Whether it’s weed purchased on the street or cannabis bought at a licensed dispensary, we generally weigh small amounts of cannabis in grams, especially when it comes to amounts less than an ounce. In the US, we typically weigh commercial goods in ounces or pounds, so why are grams the universal measurement for smaller amounts?
To understand this, we first need to distinguish two common systems of measurement: the SI, or international system of measurements, and the English or imperial system.

Although today we tend to take measurements for granted as fixed, universal units (1 inch is always exactly 1 inch, right?), historically, this wasn’t always the case. The British or imperial system traces its roots back to ancient Rome, with measurements based on commonly traded goods. For instance, in the 1300s, an “inch” was defined as the length of three “average” or “ideal” barleycorns set side-by-side. Of course, no such “ideal” seed exists.
Over the centuries, various imperialist measurements for volume, weight, and distance changed as new kings assumed control of their kingdoms. This led to a lot of headache. For example, if imperial distances were redefined, farmers had to change the boundaries of their lands by literally moving all of their fence posts. (To be fair, SI unit definitions have also changed over the centuries, but these changes are relatively tiny and largely insignificant for most practical, everyday cases.)
