4 g per level teaspoon
4 g per cube
Energy from sugar
At 4 kcal per gram
Each cube represents 4 grams of sugar.
How to read this: One level teaspoon of granulated sugar is approximately 4 g. Sugar cubes vary in weight, so choose a cube size above. The visual is a mass comparison, not a count of actual cubes in the product. The “Sugars” line on a nutrition label may include naturally occurring sugar as well as added sugar. Example values are illustrative, not verified product nutrition facts.
Ever looked at a drink label and wondered what 35 grams of sugar actually looks like? It's easy to overlook a number. It's much harder to overlook a pile of sugar cubes.
Our free Sugar Quantity Converter transforms sugar grams into everyday measurements: teaspoons, sugar cubes and estimated calories. No complicated calculations. Just a clearer picture of what's in your food and drinks.
Imagine a drink containing 35 g of sugar.
Nutrition labels give you the facts. Our converter helps make those facts easier to understand in everyday life. Here's what makes it useful.
Turn abstract sugar amounts into a familiar kitchen measurement. Discover approximately how many level teaspoons are equivalent to the grams on a label.
Everyday measurementA visual representation makes sugar quantities easier to imagine. Choose your preferred cube size and see what the equivalent amount looks like.
Visual learningExplore the energy contribution of sugar using approximately four kilocalories per gram. Simple, useful nutritional context.
Energy insightExplore preset amounts to get a feel for different sugar quantities, then enter the actual sugar content from your own food or drink.
Easy explorationCheck sugar amounts on your phone while shopping, compare snacks on a tablet or explore nutrition labels at your desktop.
Responsive interfaceSugar cubes are not all identical. Switch between 3 g, 4 g and 5 g cubes for a more relevant estimate of how many cubes your sugar amount represents.
Adjustable comparisonsThe maths behind the sugar grams to teaspoons and sugar cubes converter is straightforward. There are just two essential formulas to remember.
One level teaspoon of granulated table sugar is approximately 4 grams.
Divide the total sugar in grams by the weight of a single cube, such as 3 g, 4 g or 5 g.
Important: Teaspoon conversions use an average for level teaspoons of granulated table sugar. Actual spoon measurements can vary with sugar type, packing and spoon size. Cube conversions also depend on the cube weight selected.
Before you convert anything, you need the correct number. On many nutrition labels, sugar appears under “of which sugars” or “total sugars.” That number is your starting point.
Find the value in grams, rather than using the total carbohydrate figure.
Is the sugar amount per 100 ml, per 100 g, per serving or for the full package?
If a drink contains 10 g of sugar per 100 ml, a 330 ml portion contains 33 g.
Your result shows approximately how many teaspoons and sugar cubes it represents.

| Sugar (grams) | Teaspoons | 3 g cubes | Energy |
|---|---|---|---|
| 4 g | 1 | 1.3 | 16 kcal |
| 8 g | 2 | 2.7 | 32 kcal |
| 12 g | 3 | 4 | 48 kcal |
| 16 g | 4 | 5.3 | 64 kcal |
| 20 g | 5 | 6.7 | 80 kcal |
| 25 g | 6.25 | 8.3 | 100 kcal |
| 30 g | 7.5 | 10 | 120 kcal |
| 35 g | 8.75 | 11.7 | 140 kcal |
| 40 g | 10 | 13.3 | 160 kcal |
| 50 g | 12.5 | 16.7 | 200 kcal |
| 100 g | 25 | 33.3 | 400 kcal |
Values are approximate. Teaspoons are calculated at 4 g each; cubes at 3 g each; energy at 4 kcal per gram. The calorie column represents energy from the sugar itself, not necessarily the full food or drink.
The World Health Organization recommends that adults and children keep free sugars below 10% of total daily energy intake. A further reduction to below 5% may offer additional health benefits.
For someone consuming 2,000 calories a day, 5% of energy is approximately 25 grams of free sugars, or about 6 level teaspoons. This is an illustrative calculation, not a personalized target for everyone.
Free sugars include sugars added to foods or drinks and sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates. They do not include sugars naturally contained within intact fruits or milk.
Free sugars per day
An example based on a 2,000 kcal daily energy intake.
Remember: nutrition labels generally report total sugars. The WHO guidance refers to free sugars, so the two figures are not always directly interchangeable.
Understanding sugar quantities is useful, but knowing what to do with that information is even better. Here are three practical ways to make your next nutrition-label check more meaningful.
A small bottle and a large bottle can have similar sugar concentrations but very different total amounts. Always calculate for the portion you actually drink.
Two drinks or snacks can look almost identical but contain different amounts of sugar. Check equivalent serving sizes for a fair comparison.
Sugar content is only part of a food's nutritional profile. Consider fiber, protein, portion size and the overall dietary pattern too.
The next time a label says 12 g, 25 g or 40 g of sugar, you'll know how to turn that number into something easier to imagine. Enter the grams in the converter above and explore the result.
