Granulated Sugar Weight by Cup Size and Fraction (Extended Comparison)
Cup measurement is not same worldwide. Even same fraction like 1/2 cup or 1/3 cup gives different gram weight depending on cup system used. This extended table shows granulated sugar weight across US, UK, Australian, metric, and practical kitchen rounding. Values are realistic and meant for real cooking, not theory only.
