Understanding Brown Sugar Conversions
The Math Behind This Conversion
To convert 1 us teaspoon of brown sugar to gram, we use the density of brown sugar (0.93 g/ml). A us teaspoon contains 4.93ml, so 1 us teaspoon equals 4.93ml. Multiplying by the density: 4.93ml × 0.93 g/ml = 4.6g.
US vs Metric Cups: Why It Matters
When converting brown sugar, the cup size matters significantly. A US cup (236.6ml) of brown sugar weighs 220g, while a metric cup (250ml) weighs 233g—a difference of 12g (6%). If you're following a recipe from a different country, using the wrong cup size could affect your results. American recipes use US cups, while recipes from Australia, UK, and most other countries use metric cups.
Measurement Tip
When measuring brown sugar, pack it firmly into the measuring cup. The sugar should hold its shape when turned out. This packing method is already accounted for in our density value of 0.93 g/ml.
About Our Data
