Quick Weed Measurement Chart

Before diving deeper, here’s a quick reference chart that shows the most common weed measurements.

These measurements are based on weight, not the physical size of the buds.

Because cannabis buds vary in density, one gram of dense weed may look smaller than one gram of fluffy weed.

Why Weed Is Measured in Grams and Ounces

Cannabis is traditionally sold using both metric and imperial systems.

Grams are part of the metric system, while ounces come from the imperial system used in the United States.

This hybrid system has become standard across the cannabis industry.

Most marijuana dispensaries and online retailers like Buy My Weed USA list cannabis quantities using both measurements so buyers can easily understand what they’re purchasing.

For example:

• 1/8 ounce = 3.5 grams
  
• 1/4 ounce = 7 grams
  
• 1 ounce = 28 grams

A gram of weed is the smallest standard amount of cannabis you can purchase at most dispensaries or online stores.
