About US tablespoon (tbsp)
The US tablespoon (tbsp) is a unit of culinary volume equal to approximately 14.787 milliliters, defined as 3 US teaspoons or half a US fluid ounce. It is a fundamental cooking measurement in the United States for both liquid and dry ingredients. Butter is measured in tablespoons (1 stick = 8 tbsp), as are cooking oils, sauces, and spices. The US tablespoon differs from the Australian tablespoon (20 mL) and the imperial tablespoon (17.76 mL).
One tablespoon of olive oil is about 14 g. A standard butter portion is 1 tbsp (≈ 14 g).
About Cubic inch (in³)
A cubic inch (in³) is the volume of a cube with 1-inch sides, equal to approximately 16.387 milliliters. In the US, it is used for engine displacement (the classic Chevrolet 350 = 350 in³ ≈ 5.7 L), small container volumes, and pharmaceutical packaging. Car engine displacement was historically described in cubic inches before the automotive industry switched to liters in the 1980s–1990s. The unit also appears in 3D printing and medical device specifications.
A classic Chevy 350 V8 engine displaces 350 in³ (≈ 5.7 L). A standard tennis ball has a volume of about 15 in³.

Cubic inch – Frequently Asked Questions
What is a cubic inch in milliliters?
One cubic inch equals approximately 16.387 mL. This follows from 1 inch = 2.54 cm, so 1 in³ = 2.54³ cm³ = 16.387 cm³ = 16.387 mL.
Why are car engines measured in cubic inches?
American car engines were historically described in cubic inches of displacement. The 350, 427, and 454 in³ engines are iconic V8 ratings. Most manufacturers switched to liters in the 1980s–1990s, but cubic inches remain part of classic car culture.
How many cubic inches are in a liter?
One liter equals approximately 61.024 cubic inches. A 350 in³ engine is approximately 5.74 liters.
What is cubic inch used for today?
Cubic inches are still used in the US for motorcycle and small engine displacement, small packaging volumes, and some industrial contexts. 3D printer filament usage is sometimes estimated in cubic inches.
How does cubic inch relate to fluid ounce?
One US fluid ounce equals approximately 1.805 cubic inches. One cubic inch equals about 0.554 US fluid ounces. These conversions are used in packaging design and liquid container manufacturing.
