Why Cup Sizes Differ
Different countries developed their own cup measurements based on historical standards. The US cup derives from traditional imperial measurements, while Asian countries adopted metric-based measurements. These differences can affect recipe outcomes, especially in baking.
When It Matters Most
The difference between cup sizes (ranging from 180ml to 250ml) can significantly impact precise baking recipes like cakes, pastries, and bread. For soups and stews, the variation is less critical. Always check which cup standard your recipe uses.

- Japanese and Korean recipes typically use 200ml cups
- Rice cooker cups (180ml) are specifically for measuring uncooked rice, not for general cooking
- For precision baking, consider using weight measurements (grams) instead of cups
- US recipes may use either 240ml or 250ml cups - when in doubt, use 240ml for better accuracy
