Why Weigh Brown Sugar in Grams?
When a recipe calls for 3 cups of brown sugar, using a kitchen scale to measure exactly 660 grams will give you far more consistent results than volume measurement alone. This is because brown sugar can be packed, sifted, or scooped differently each time, leading to weight variations of up to 20%.
How to Measure Brown Sugar by Weight
Place your mixing bowl on a digital kitchen scale and press "tare" to zero it out. Then add brown sugar until the scale reads 660g. This method is faster than measuring cups and eliminates the guesswork entirely.
Also Known As
Brown Sugar is sometimes referred to as light brown sugar, dark brown sugar. The same conversion of 220g per cup applies regardless of the name used.
