How Is Cocaine Measured? Weights (Grams & Ounces) & Common Terms Explained (2026 Guide)
May
Cocaine is typically measured in grams, ounces, and kilograms, with common street terms like “8 ball” representing specific weights. Understanding these units helps clarify how quantities are calculated and why measurements vary. Navigating these weights is often confusing because the terminology mixes the metric system with old imperial units. This 2026 guide explains exactly how these units work so you can understand the math behind the scales.

This guide is for informational and harm-reduction purposes only. It does not encourage or facilitate illegal activity. Understanding drug measurements helps reduce risk, identify short weights, and prevent accidental overdose by emphasizing the dangers of unknown purities.
Quick Answer: How Is Cocaine Measured?
- 1 gram = 1g
- Half ounce = 14g
- 1 ounce = 28g
- 1 kilo = 1000g
- 8 ball = 3.5g
Cocaine is measured in grams for small amounts and ounces or kilograms for larger quantities. The most common consumer unit is the eight ball, which is 3.5 grams, representing exactly one-eighth of a standard 28-gram ounce.
How Cocaine Is Measured (In Simple Terms)
Cocaine is measured using:
- Grams for small amounts
- Ounces for mid-level quantities
- Kilograms for bulk distribution
The most common unit is the eight ball (3.5 grams), which equals one-eighth of an ounce.
Cocaine Weight Conversion Table

| Ounce | Zip | 28.0g | 8 eight balls |
| Kilogram | Key / Brick | 1000g | ~36 ounces |
Cocaine Measurements Explained (Simple)
- 1 gram = 1g
- 1 eight ball = 3.5g
- 1 quarter ounce = 7g
- 1 half ounce = 14g
- 1 ounce = 28g
- 1 kilo = 1000g
What Is Cocaine Measurement?
In the simplest terms, cocaine measurement is the act of determining the mass of a powder or solid “rock” using the metric system. Because this substance is highly potent and expensive, even a tiny difference in weight matters.
The system works by breaking down larger units into smaller ones. For example, a kilogram is 1,000 grams. In the United States, wholesalers often switch to the imperial system, using the ounce as the primary bridge. One scientific ounce is roughly 28.35 grams, but in the street trade, this is almost always rounded down to an even 28 grams to make the math for smaller portions easier to calculate. If you are looking to understand the broader picture, knowing the different types of cocaine and their effects is just as important as knowing the weights.
Common Cocaine Weights & Units
Understanding the specific numbers helps you identify exactly what you are looking at. Here are the most common units used today.
The Half Gram (0.5g)
This is often the smallest unit available. It is frequently called a “fiftie” or a “half-a-G.” It is a very small amount, typically used for personal, single-use quantities.
The Full Gram (1.0g)
The gram is the universal base unit for most users. It is exactly 1.0 grams on a scale—about the size of a small paperclip. This is the standard unit for evaluating purity and pricing.
The “Teeth” or “Teezie” (1.75g)
This unit is exactly half of an eight ball. It is an uncommon measurement in some areas but popular in others where individuals want more than a gram but cannot afford a full ball.
The Eight Ball (3.5g)
The eight ball is the most iconic measurement in the industry. If you want to know what an 8 ball of cocaine is, it is exactly 3.5 grams, representing 1/8th of an ounce.
The Quarter Ounce (7.0g)
A “quad” or quarter consists of two eight balls. When calculating the grams in a quarter ounce, the answer is exactly 7.0 grams. This is a bulkier consumer amount that offers a better price per gram.
How Many Grams in Half Oz of Coke?
There are exactly 14 grams in a half ounce of cocaine. This is equivalent to four eight balls.
How Many Grams in an Ounce of Coke?
There are exactly 28 grams in an ounce of cocaine. While a scientific ounce is 28.35g, the street trade rounds it down to 28.0g for easier math. If you want to know how many eight balls are in an ounce, the math is 28 divided by 3.5, which equals exactly 8.
How Many Grams in a Kilo of Coke?
There are exactly 1,000 grams in a kilo of cocaine. A “key” or “kilo” is the standard international shipping unit. If you want to know how many 8 balls are in a kilo, the math is 1000 divided by 3.5, which equals roughly 285.7 eight balls.
Bulk Weights: Bricks
A brick is simply a kilogram of cocaine that has been pressed into a hard, solid block for transport. When asking how many grams are in a brick, it is the same as a kilo: 1,000 grams. High-grade product is sometimes referred to as Peruvian coke, but the weight remains standardized at 1,000g per brick.
Why Accurate Measurement Matters (Harm Reduction)
Accurate measurement is critical because even small differences in weight can increase risk. Health organizations and harm-reduction advocates emphasize that knowing the exact amount of a substance is vital for safety.
Eyeballing or guessing quantities is incredibly dangerous and often leads to accidental overdoses. Using precise digital scales rather than visual estimation ensures that individuals know exactly what they are handling. Furthermore, purity varies wildly—a gram of pure material is much stronger than a gram of heavily diluted powder. To understand if an 8 ball is always 3.5 grams, you have to account for cutting agents.
Why Measurement Confusion Happens
You might wonder why there is so much debate over a simple number on a scale. There are four main reasons why measurement errors and misunderstandings are common.
Inaccurate Tools
Many people use cheap kitchen scales or “pocket” scales that are not sensitive enough to detect 0.1-gram increments, leading to false readings.
The “Short” Ounce
Some regions use a “Mexican Ounce” or “St. Louis Ounce” which is only 25 grams instead of 28, leading to smaller individual portions.
Packaging Weight
Beginners often forget to “tare” the scale, meaning they accidentally include the weight of the plastic baggie in the total.
Cutting Agents
While the total weight might be correct, the amount of actual active substance varies if the powder is mixed with fillers.
How Much Does a Bag of Coke Weigh?
The weight of a “bag” depends entirely on the quantity purchased. There is no standard “bag” size. A small $20 bag might contain 0.2g to 0.3g, while a “half-a-G” contains 0.5g. If someone purchases an 8-ball, the bag should contain exactly 3.5 grams. Always weigh the product out of the bag, as plastic bags can weigh between 0.2g and 0.5g, which adds up quickly when paying premium prices.
Safety & Best Practices
When dealing with any substance, accuracy is about more than just money—it is about safety. Using more than intended because of a measurement error can lead to severe health risks, including overdose. If you are aware of the dangers of an 8 ball of drugs, you know that even a small miscalculation can be fatal. Be smart, stay informed, and always prioritize harm reduction.
