About Tablespoon (US)

The US tablespoon is 1/2 US fluid ounce (about 14.7868 ml). US recipes use tablespoons for cooking volumes.

About Cubic Feet

The cubic feet is the volume of a cube one feet on a side (about 28.3168 liters). HVAC, construction, and US freight sometimes use cubic feet.

How to convert tablespoons (us) to cubic feet

1 tablespoon (us) is equal to 0.00052218967014 cubic feet:

1 tbsp = (0.01478676478125 L ÷ 28.316846592 L) ft3 = 0.00052218967014 ft3

Each tablespoon (us) is defined as 0.01478676478125 L and each cubic feet as 28.316846592 L, so one tbsp equals 0.01478676478125 ÷ 28.316846592 ft3 = 0.00052218967014 ft3.

Let V(tbsp) be the numeric value of the same volume measured in Tablespoon (US) (tbsp), and V(ft3) the value in Cubic Feet (ft3). Then:

V(ft3) = V(tbsp) × (0.01478676478125 / 28.316846592)

Equivalently, divide by how many tbsp fit into one ft3 (liters per ft3 divided by liters per tbsp):

V(ft3) = V(tbsp) ÷ 1915.0129870129872

Or: cubic feet = tablespoon (us) ÷ 1915.0129870129872

Examples

Example #1: Convert 20 tbsp to cubic feet

20 tbsp = 20 tbsp × (0.01478676478125/28.316846592) ft3 = 0.0104437934 ft3

20 tbsp = 20 tbsp ÷ 1915.0129870129872 = 0.0104437934 ft3

Example #2: Convert 50 tbsp to cubic feet

50 tbsp = 50 tbsp × (0.01478676478125/28.316846592) ft3 = 0.0261094835 ft3

50 tbsp = 50 tbsp ÷ 1915.0129870129872 = 0.0261094835 ft3

Summary

To convert Tablespoon (US) to Cubic Feet, multiply the value in tbsp by the ratio of liters per tbsp divided by liters per ft3. Equivalently: value_ft3 = value_tbsp × (0.01478676478125 / 28.316846592). Numerically, 1 tbsp equals 0.0005221896701388889 ft3.
