There are 16 tablespoons (tbs) in one cup according to the United States customary system for measuring liquids. This conversion factor is widely used in recipes and cooking instructions in the United States.
It's important to remember that different countries might use different volume units and conversion factors. For precise measurements, especially when dealing with large quantities, it's recommended to use metric units (liters, milliliters) or rely on measuring tools specific to the desired unit (e.g., measuring cups, tablespoons).
