The tablespoon (US) is a unit of volume used in the US customary system. It's commonly abbreviated as tbsp, T, or tbs, and it plays a central role in measuring both liquid and dry ingredients in American recipes. By definition, one US tablespoon equals 14.7868 milliliters, making it exactly three times the size of a US teaspoon.
This unit is a standard part of measuring spoon sets found in nearly every American kitchen. It's used for ingredients that require more than a teaspoon but less than a full cup—like oil, syrup, peanut butter, or baking powder. Whether you're preparing a sauce, salad dressing, or baked goods, the tablespoon offers an ideal balance between precision and practicality.
Uses: The tablespoon is one of the most commonly used measurements in American kitchens. You’ll find it in countless recipes—from marinades and sauces to pancake batter and salad dressings. In baking, it plays a critical role, where just a small difference in the amount of butter, oil, or leavening agent can change the texture or taste of the final dish. The tablespoon is also used in meal prep, portion control, and nutritional labeling, helping consumers track ingredients like sugar, oils, or dressings in a standardized way.
Beyond the kitchen, the U.S. tablespoon occasionally appears in medical or pharmaceutical contexts to measure over-the-counter liquid medications, though healthcare professionals typically recommend using milliliters for precision. Still, the tablespoon remains a familiar and convenient reference point for many households.
A cubic foot is a unit of volume used in the imperial and U.S. customary measurement systems. It represents the space occupied by a cube with sides that are each one foot long. One cubic foot is equal to 1,728 cubic inches or approximately 28.3168 liters. It's commonly abbreviated as ft³ and is typically used for measuring larger volumes, especially in construction, storage, and shipping.
Unlike units like milliliters or teaspoons, the cubic foot is designed for measuring bulk quantities or physical space. The cubic foot is often used when measuring things like the volume of a box, the size of a freezer, or how much air moves through a ventilation system. It serves as a practical unit for working with larger volumes in everyday and industrial settings.
Uses: The cubic foot is widely used in industries where space and volume matter. It's commonly seen in construction when calculating the volume of concrete, soil, or insulation. In shipping and logistics, it's used to estimate the capacity of containers and freight. Appliances like refrigerators, freezers, and ovens often list their internal capacity in cubic feet to help buyers compare storage space.
In everyday use, the cubic foot might show up when measuring a moving box's size, determining garage storage space, or calculating how much mulch is needed for a garden bed. It remains a trusted unit for real-world measurements where larger volumes are involved.
1 tbsp = 0.000522 ft³
Let’s say you want to convert 100 tbsp to ft³.
Using the formula:
100 × 0.000522 = 0.052 ft³
So, 100 tbsp is approximately 0.052 ft³.
