Cubic Inch
A cubic inch (in³) is a US customary unit of volume based on the space inside a cube that measures one inch on each side. It’s commonly used in engineering, product dimensions, and specifications for items such as computer cases, shipping packages, and engine displacement. Although not as widely used as liters or milliliters, cubic inches remain important in industries where US measurement standards apply.
Converting cubic inches to metric units—like cubic centimeters or liters—can be tricky because the systems use different base measurements. An online converter helps provide fast and accurate translations, especially when comparing US and international product sizes.
Tablespoon
A tablespoon (tbsp) is a common US customary unit of volume often used in cooking and measuring small quantities of ingredients. One tablespoon equals 3 teaspoons or about 14.79 milliliters, making it a practical unit for sauces, oils, spices, and baking ingredients. Because it appears in nearly every recipe, the tablespoon is a familiar part of kitchen measurement tools.
When converting tablespoons to other units — such as cups, teaspoons, or milliliters — the numbers don’t always convert cleanly. A converter helps ensure accuracy so recipes turn out correctly, especially when working with international sources that use metric measurements.
