- 1Take your value in tablespoonsStart with the number of tablespoons (tbsp) you want to convert.
- 2Multiply by 0.000523The conversion factor from tbsp to ft³ is 0.000523. Multiply your value by this number.
- 3Read the result in cubic feetThe result is your value in cubic feet (ft³).
Formula
Multiply the value in tablespoons by 0.000523. For the reverse direction, multiply by 1,913.3004.
ft³ = tbsp × 0.000523tbsp = ft³ × 1,913.3004Tips
Use these in everyday conversions- US tbsp = 15 ml (practical); 14.787 ml (legal); 3 teaspoons in any system.
- Australian tablespoon = 20 ml — 33% larger. Adjust when using Australian recipes.
- For accurate cooking, weigh dry ingredients rather than measuring by tablespoon.
Common Mistakes
Avoid these- Using an Australian tablespoon (20 ml) for a US recipe (15 ml) — 33% overshoot.
- Treating teaspoon and tablespoon as interchangeable — tablespoon is 3× larger.
- Using a dinner spoon from the cutlery drawer as a tablespoon — they vary widely.
About Tablespoon and Cubic Foot
What is the Tablespoon?
The tablespoon equals exactly 15 milliliters (international culinary standard) or about 14.787 mL (US strict definition based on ½ fluid ounce). The tablespoon is a near-universal cooking measure for ingredients larger than a teaspoon but smaller than a cup — typical uses include oils, sauces, and condiments. The Australian tablespoon is uniquely 20 mL (4 teaspoons rather than 3), an oddity in international recipe interpretation. Standard recipes assume 1 tbsp = 15 mL globally except in Australia and the United States (where it is sometimes 14.787 mL but commonly rounded to 15 mL). The tablespoon relates to the teaspoon (3 tsp = 1 tbsp), the cup (16 tbsp = 1 cup), the fluid ounce (2 tbsp = 1 US fl oz), and the milliliter (1 tbsp = 15 mL conventional). Measuring spoons are calibrated to the local convention.
- Cooking recipes worldwide (dominantly US 15 ml)
- Nutrition-label serving sizes
- Over-the-counter liquid-medication doses
Olive-oil recipes call for tablespoons of oil. Cough syrups often recommend 1 tbsp = 15 ml per dose.
What is the Cubic Foot?
The cubic foot equals approximately 28.317 liters (or exactly 1,728 cubic inches) and is the American standard volume unit for HVAC capacity, natural-gas billing, refrigerator interior volume, and bulk material like concrete or mulch. American gas utilities measure delivered gas in 'CCF' (hundred cubic feet) or 'MCF' (thousand cubic feet), even when the customer thinks in terms of monthly bills. Refrigerators are advertised by their interior cubic-foot capacity (typical home unit: 18–25 ft³). Air-conditioning systems are rated in CFM (cubic feet per minute) airflow. Concrete is sometimes priced by the cubic yard (27 ft³), and mulch and topsoil are often sold by cubic foot bags. The cubic foot relates to the cubic yard (27 ft³ = 1 yd³), the cubic inch (1,728 in³ = 1 ft³), the cubic meter (1 ft³ ≈ 0.0283 m³), and the gallon (1 ft³ ≈ 7.481 US gal).
- US air-conditioning and ventilation flow (CFM)
- US natural gas consumption
- Refrigerator and freezer capacity in the US
A typical US fridge is 20 cu ft (566 L). US HVAC flow rated in CFM. US residential gas billed per 100 cu ft (CCF).
