Should I Measure Sugar by Weight or Volume?

Many experts are adamant that dry ingredients like sugar should be measured by weight instead of volume, especially when used for baking.

The reason is that the density of different sugars vary slightly, so volume measurements will likely yield an incorrect amount of ingredient. Additionally, when using a cup or tablespoon, the amount that the sugar is compressed and above or under the measurement line will alter the actual amount.

This is why most experts suggest using a food scale to measure sugar when cooking, rather than a cup, tablespoon, or other volume measuring devices.
