Why Cup-to-mL Conversion Matters

American recipes use cups, while European, Asian, and most international recipes use milliliters or grams. If you’re following a recipe from a different country, you need precise conversion. Baking is particularly sensitive β€” too much or too little flour can ruin a cake.
