The idea
Why make sugar visible?
A number on a label is easy to skim past. "14 g per 100 ml" means very little until you scale it to the thing you are actually holding — and then watch that amount pile up.
SugarScale does exactly one thing. It takes the value from the nutrition table, multiplies it by your serving size, and turns the result into a quantity you can recognise: grams on a scale, and sugar cubes in a glass.
The formula
sugar per 100 ml × amount ÷ 100 = total sugar
Worked example
- 14 g per 100 ml
- 500 ml can
70 g of sugar
about 17–18 sugar cubes
- 1
Read the label
Nutrition tables list sugar per 100 ml for drinks and per 100 g for foods.
- 2
Scale it to the serving
Multiply by what is really in the bottle, the can or the bowl — not the reference amount.

See the quantity
Grams, cube equivalents and a glass that fills in real time as the numbers change.
Context
What the daily value actually means
Numbers are only useful with something to compare them to. Here is the orientation SugarScale uses, and what it does and does not cover.
Roughly 25–50 g a day
The WHO recommends keeping free sugars below 10 % of total energy intake, and notes additional benefits below 5 %. At a 2000 kcal reference intake that works out at about 50 g and 25 g respectively. SugarScale uses 50 g as its orientation value.
Free sugars, not all sugars
That guidance covers free sugars: sugars added to food and drink, plus those naturally present in honey, syrups and fruit juices. Sugar in whole fruit and the lactose in plain milk are not counted as free sugars.
One cube ≈ 4 g
The sugar cube is a unit of recognition rather than a nutrition unit. It exists here because most people can picture four grams as a cube far more easily than as a number.
No forbidden foods
Sugar is not something to eliminate, and this is not medical or dietary advice. The point is simply that the amount should not be a surprise. What you do with the number is your call.
