Measuring Tip
Brown sugar should always be firmly packed into the measuring cup unless specified otherwise. Loosely measured brown sugar can weigh 15-20% less than packed.
Understanding the Units
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
What is a Cup?
There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.

Close, but not exactly. The ounces to cups conversion for brown sugar may vary slightly between brands depending on moisture content and how the ingredient is measured.
The same weight of different ingredients fills different volumes because each ingredient has a different density. An ounce of brown sugar fills a different number of cups than an ounce of a lighter or heavier ingredient. That is why this converter needs to know which ingredient you are measuring.
