How to Use the Sugar Cube Converter
Nutrition labels on snacks and drinks just list a number like "Sugars 12g," which doesn't really tell you how sweet that actually is. This calculator takes the sugar figure (g) from a label and converts it into the more intuitive unit of sugar cubes. Since one standard cube equals 4g, a bottle of soda with 24g of sugar works out to roughly 6 cubes.
It also calculates what percentage of the WHO's recommended daily free sugar limit of 25g that food represents. If the result passes 100%, that single item alone already covers your entire daily sugar allowance.
Check this calculator before buying drinks, snacks, or sauces — foods where sugar tends to hide — and a label you'd normally skip past suddenly becomes much more concrete information. If you eat several sugary foods in one day, adding up each item's percentage is a good habit for tracking your total intake.
Frequently Asked Questions
One standard sugar cube is about 4g of sugar. This calculator uses that figure to convert the sugar amount on a nutrition label into an equivalent number of cubes.
The WHO recommends keeping free sugar intake under 10% of daily calories, ideally under 5% (about 25g). This calculator uses 25g as the reference amount.
