How to Convert Tablespoons of Sugar to Cups

To convert a tablespoon measurement to a cup measurement, divide the sugar by the conversion ratio. One cup of sugar is equal to 16 tablespoons, so use this simple formula to convert:

cups = tablespoons ÷ 16

The sugar in cups is equal to the tablespoons divided by 16.

For example, here's how to convert 5 tablespoons to cups using the formula above.
5 tbsp = (5 ÷ 16) = 0.3125 c

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.
