Beverages are one of the easiest places to blow a daily carb budget, yet their labels often list carbs per serving or per 100 ml, not per 100g. This can make it tricky to compare a 330 ml cola, a 240 ml juice, and a 150 ml glass of wine on an equal footing. The Drink Carbs Per 100g Calculator solves that by standardizing any drink to grams of carbs per 100 g, so you can compare options and calculate exactly how many carbs are in the amount you actually pour.
Use it to convert label data, check a favorite drink against a preset, or plan for a low-carb, keto, or diabetic-friendly day. If you enter a daily carb target, the tool also shows what fraction of your goal one drink uses up. The math assumes 1 ml of liquid weighs about 1 g, which holds for most water-based beverages.

How to Use This Tool
This calculator takes the nutrition information already printed on your drink label and converts it into a standard per-100g value. Follow these steps:
- Select a drink from the dropdown to auto-fill typical values, or leave it on “Custom drink”.
- Enter the total carbs per serving in grams and the serving size in millilitres from the nutrition panel.
- Enter the amount of drink you plan to consume. The quick-fill buttons (250 ml, 330 ml, 500 ml, 750 ml) save time for common bottle and glass sizes.
- Adjust the daily carb target if you track against a specific goal. The default of 275 g is a reference for a 2,000-calorie diet, but you can change it to your own macro target.
- Click Calculate to see carbs per 100 g, carbs per serving, carbs in your actual amount, and the percentage of your daily target used.
How the Calculation Works
Nutrition labels for beverages usually report carbohydrates either per serving or per 100 ml. Since almost all still drinks have a density very close to 1 g per ml, a per-100ml value is effectively the same as a per-100g value. The calculation uses two simple formulas:
Carbs per 100 g = (total carbs in serving ÷ serving size in ml) × 100
Total carbs in your drink = (carbs per 100 g ÷ 100) × amount you drank
For example, a 240 ml orange juice with 23 g of carbs gives 23 ÷ 240 × 100 = 9.6 g per 100 g. If you pour 300 ml, that is 9.6 ÷ 100 × 300 = 28.8 g of carbs.
Worked Examples
Example 1: Cola
A 330 ml can of regular cola lists 35 g of carbs for the whole can. Per 100 g: 35 ÷ 330 × 100 = 10.6 g. If you drink the whole can, you get all 35 g. Against a 275 g daily target, that’s 35 ÷ 275 × 100 = 12.7% of your carbs before you’ve eaten anything.
Example 2: Wine
A 150 ml glass of red wine contains about 3.9 g of carbs. Per 100 g: 3.9 ÷ 150 × 100 = 2.6 g. If you have a 250 ml pour, total carbs = 2.6 ÷ 100 × 250 = 6.5 g — much lower than the cola, although alcohol calories still matter.
Reference Table: Carbs in Popular Drinks
The values below are approximate, rounded from USDA FoodData Central and manufacturer nutrition panels. Always use the label on your actual drink for the most accurate result.
| Drink | Carbs per 100 ml | Typical serving | Carbs per serving |
|---|---|---|---|
| Regular cola | 10.6 g | 330 ml | 35.0 g |
| Orange juice | 9.5 g | 240 ml | 22.8 g |
| Apple juice | 11.6 g | 240 ml | 27.8 g |
| Skim milk | 4.8 g | 240 ml | 11.5 g |
| Regular beer | 3.5 g | 355 ml | 12.4 g |
| Red wine | 2.6 g | 150 ml | 3.9 g |
| Energy drink | 11.0 g | 250 ml | 27.5 g |
| Sports drink | 6.0 g | 355 ml | 21.3 g |
| Sweetened iced tea | 8.5 g | 240 ml | 20.4 g |
Tips & Best Practices
- Check the serving size. Many bottles look like one serving but actually contain 2–3 servings. Multiply the label carbs by the number of servings you drink.
- Use per-100g for quick comparisons. A drink with 9 g per 100g pours about 33% more carbs into the same glass than one with 6.8 g per 100g.
- Watch portion size. The per-100g number is a concentration; your total carb load still depends on how much you pour. A low-per-100g drink in a giant cup can deliver more carbs than a small glass of a higher-carb drink.
- For alcohol, count carbs but not only carbs. Alcohol itself is not a carb, but beer and sweet wines often contain maltose and residual sugar. Cocktails with juice or syrup can be carb-heavy.
- Net carbs are different. If you subtract fiber and sugar alcohols, use a dedicated net carb approach. For drinks with artificial sweeteners, see the sports net carbs calculator for a more detailed look at low-sugar beverages.
- Prefer plain options. Water, sparkling water, unsweetened coffee and tea contain zero carbs and are the easiest choice on a low-carb day.
Factors Affecting Accuracy
This tool gives a strong estimate, but a few factors can cause small differences between the calculated number and your actual carb intake:
- Density: The 1 ml ≈ 1 g assumption is excellent for water, coffee, tea, and most soft drinks. Sugar-heavy syrups or creamy smoothies can be slightly denser, which means the true carbs per gram may be a little lower than the per-ml value.
- Label rounding: Manufacturers often round carbohydrate values to the nearest whole gram. For a small serving, rounding can shift the per-100g result by 0.5–1 g.
- Ice and temperature: Ice adds water volume but no carbs, so a drink with lots of melting ice will have a more dilute carb concentration than the label suggests.
- Recipe variation: Fresh-squeezed juice, bar-made cocktails, and homemade smoothies vary from batch to batch. When in doubt, measure ingredients or use the manufacturer’s prepared-drink values.
