About Cubic Inches
A cubic inch (in³) is the volume of a cube with sides of one inch (25.4 mm), equal to approximately 16.387 mL. It is widely used in US engineering and manufacturing - engine displacement was traditionally described in cubic inches (a 350 in³ V8 engine displaces 5.7 liters), and product specifications for items sold in the US frequently reference cubic inches. Speaker cabinet volumes, wine bottle capacities in older US standards, refrigerator compartment sizes, and box shipping calculations in imperial units all use cubic inches. One liter equals approximately 61.024 cubic inches.
About Teaspoons
A teaspoon (tsp) is a US customary and cooking measurement unit equal to 1/3 of a tablespoon - approximately 4.929 mL. It is fundamental to cooking and baking worldwide: nearly every recipe in US-published cookbooks uses teaspoons as the basic small measurement for spices, baking powder, vanilla, and other minor ingredients. In medicine, over-the-counter liquid medications (especially children's doses) are measured in teaspoons, with 5 mL the standard metric equivalent used on US medication labels. Three teaspoons make one tablespoon, and six teaspoons make one fluid ounce.
