Navigating the conversion between grams and cups can be a culinary puzzle. Whether you’re pondering the quantity of flour for a cake or the perfect sugar ratio, our converter is here to demystify the process. Let’s explore the essential equations and cup variations to ensure accurate conversions.

Conversion Equations

To convert between grams and cups, we utilize the following general equations:

Weight = Cups × Cup Size × Density

Cups = Weight / (Cup Size × Density)

These formulas highlight the need for density information, making it crucial to consider the recipe’s country of origin due to different cup sizes.

Cup Varieties

Various cup sizes are used globally, including the US customary cup (236.59 mL), the US legal cup (240 mL), the UK, AU, NZ, CA, and ZA metric cup (250 mL), and the UK imperial cup (284.13 mL, pre-1970). Japan has its cup (200 mL), and Latin America varies between 200-250 mL.
