In kitchens across the United States, when measuring ingredients for a recipe, it’s typically in teaspoons, tablespoons, and cups. These units are part of the Imperial measurement system, which is the standard in America. However, the rest of the world measures things in metrics.
The Metric system, also known as the International System of Units, is a decimal-based system that uses meter, liter, and gram as units of length, capacity, and weight or mass.
Understanding Imperial to Metric equivalents can be helpful when using international recipes or for more precise measurements, especially when baking. This chart will help with the basic U.S. Standard to Metric conversions for cups to millimeters.
