Regular cola is one of the most popular beverages in the world, and it is also one of the easiest places to rack up added sugar without realizing it. A standard 330 ml can of regular cola typically contains about 35 grams of sugar — more than eight teaspoons. This calculator helps you find out exactly how much sugar is in any serving of cola, expressed both as total grams and as grams per 100 g. It works with milliliters, liters, fluid ounces, cups, or grams by weight, and it includes presets for regular, generic-style, and diet cola.
Why per 100 g? Nutrition labels in many countries use per 100 ml for drinks, but diet coaches, food databases, and macro trackers often compare foods on a weight basis. Because cola is slightly denser than water (about 1.04 g/ml), the sugar per 100 ml is not the same as the sugar per 100 g. This tool does the conversion for you, using a density value you can adjust.
Use it to check a single can, a restaurant cup, a movie-theater bucket, or even a homemade cola recipe. Results include teaspoon equivalents and the calories that come from sugar, making it easy to fit cola into a daily sugar budget or a weight-loss plan.

How to Use This Tool
This calculator is designed for anyone who wants to convert a typical cola serving into grams of sugar, both for the whole serving and for a 100 g reference portion. Start by selecting the type of cola you are drinking. The preset options cover regular cola, a slightly sweeter generic/Pepsi-style cola, and diet/zero-sugar cola. If your brand does not match any preset, choose “Custom cola” and type in the label’s sugar-per-100-ml value.
Next, enter the serving size and choose the unit. The most accurate option is milliliters, because nutrition labels usually report cola sugar in grams per 100 ml. You can also enter liters, US fluid ounces, US cups, or grams by weight. The quick-fill buttons below the serving field insert common container sizes: a 200 ml glass, 250 ml cup, 330 ml can, or 500 ml bottle.
The density field defaults to 1.04 g/ml, which is close to the density of regular cola. Leave it as-is unless you are using a laboratory-measured value or a homemade syrup variation. Click “Calculate sugar” to see total sugar, sugar per 100 g, teaspoon equivalents, and the calories that come from sugar.
Tip: If you already weigh your drink on a kitchen scale, choose “grams (weight)” in the unit dropdown. That skips the volume-to-weight conversion and uses your measured mass directly.
The Math Behind the Calculator
Regular cola is about 90 percent water, but the dissolved sugars and other solids raise its density above plain water. A 100 ml portion of regular cola therefore weighs about 104 g, not 100 g. When a label says “10.6 g sugar per 100 ml,” the same drink contains roughly 10.2 g sugar per 100 g because you divide the per-100-ml value by the density in g/ml:
Sugar per 100 g = sugar per 100 ml ÷ density.
For a volume-based serving, total sugar is simply:
Total sugar = sugar per 100 ml × (volume in ml ÷ 100).
For a weight-based serving, the tool first converts the label value to sugar per 100 g, then multiplies by the measured weight divided by 100:
Total sugar = (sugar per 100 ml ÷ density) × (weight in g ÷ 100).
The teaspoon conversion uses 4.2 g of sugar per level teaspoon, and the calorie estimate uses 4 kcal per gram of carbohydrate sugar. Both are standard approximations used in nutrition education.
Worked Examples
Example 1: 330 ml can of regular cola. Using 10.6 g/100 ml and density 1.04: total sugar = 10.6 × 330 ÷ 100 = 35.0 g. Sugar per 100 g = 10.6 ÷ 1.04 = 10.2 g. That equals about 8.3 teaspoons and 140 kcal from sugar.
Example 2: 500 ml bottle of generic cola. Using 11.0 g/100 ml: total sugar = 11.0 × 500 ÷ 100 = 55.0 g. Sugar per 100 g = 11.0 ÷ 1.04 = 10.6 g. That is about 13.1 teaspoons and 220 kcal from sugar.
Example 3: 355 ml diet cola. The preset is 0 g sugar, so the total is 0 g, the per-100-g value is 0 g, and it contributes no sugar calories. Some diet drinks contain other sweeteners or trace carbohydrates, so always check the label if you track total carbs.
Typical Sugar Values in Cola
Values on labels vary slightly by country, brand, and recipe. The table shows the common approximations used by this calculator.
| Cola type | g sugar per 100 ml | g sugar per 100 g |
|---|---|---|
| Regular cola (Coca-Cola® style) | 10.6 | 10.2 |
| Generic / Pepsi® style | 11.0 | 10.6 |
| Diet / zero-sugar cola | 0.0 | 0.0 |
The per-100-g values assume a density of 1.04 g/ml. If you are working with a different brand or a homemade cola, use the custom sugar field and enter the value printed on the label.
Common Mistakes to Avoid
- Treating milliliters as grams. Regular cola weighs more than water, so 100 ml of cola is not 100 g. Using 1 g/ml instead of 1.04 g/ml makes the per-100-g result about 4 percent too high.
- Copying a US label’s per-serving value without adjusting. A 12 fl oz can in the US contains 355 ml, not 330 ml. If the serving is labeled as “one can,” enter the can’s actual volume in the tool.
- Confusing US and imperial fluid ounces. This calculator uses US fluid ounces (29.5735 ml). Imperial fluid ounces are 28.413 ml, a roughly 4 percent difference.
- Assuming all cola brands have identical sugar. Some regional colas are sweetened with cane sugar, while others use high-fructose corn syrup, and the sugar content can differ by a gram or more per 100 ml.
- Forgetting the density when tracking by weight. If you weigh your drink, the total sugar still depends on the label’s per-100-ml value, which must be adjusted for the drink’s density.
Frequently Asked Questions
How many grams of sugar are in a typical can of cola? A 330 ml can of regular cola at 10.6 g/100 ml contains about 35 g of sugar. A US 355 ml can contains about 37.6 g. This is equivalent to roughly 8 to 9 teaspoons.
Why does “sugar per 100 g” look slightly lower than “sugar per 100 ml”? Because 100 ml of cola weighs about 104 g. The same sugar is spread over a larger mass, so the per-100-g number is about 4 percent smaller.
Does diet cola contain zero sugar? Most diet and zero-sugar colas contain no sucrose, glucose, or fructose and are sweetened with artificial or plant-based sweeteners. They may still contain negligible calories and trace carbs; check the label if you are tracking total carbohydrates or keto macros.
How does cola’s sugar compare with other beverages? Regular cola is among the higher-sugar soft drinks. For comparison, beer usually contains very little sugar because fermentation consumes most of it — see this beer sugar per 100g calculator. For packaged sweets, the candy sugar calculator is another useful reference.
