A cubic inch is a unit of volume used in the imperial and U.S. customary systems. It represents the space occupied by a cube, with each side measuring exactly one inch. One cubic inch is equal to 16.387 milliliters or approximately 0.0005787 cubic feet, and it's abbreviated as in³.
The cubic inch is often used to measure smaller volumes in areas like automotive design, mechanical components, and product manufacturing. It’s a go-to unit for things like engine size, compact storage, and custom parts where detailed, space-specific measurements are needed.
Uses: The cubic inch is most widely recognized in the automotive world, where it's often used to express engine size—especially in classic American vehicles. It's also used in engineering and manufacturing for parts design, packaging, and product specifications where precision is important.
In everyday use, you might see cubic inches listed when measuring the internal dimensions of a drawer, estimating the volume of a small box, or comparing product capacities. It remains a trusted unit for capturing volume in tight spaces where accuracy matters.
A teaspoon (US) is a unit of volume measurement commonly used in American kitchens and food labeling. It is part of the US customary system and is typically abbreviated as "tsp." One US teaspoon is defined as exactly 4.92892 milliliters. It's also equivalent to one-third of a US tablespoon and one forty-eighth of a US cup.
This unit is frequently seen in recipes for small quantities of ingredients like salt, baking powder, or vanilla extract. It's also a common part of household measuring spoon sets, which usually include ¼, ½, and 1 teaspoon sizes.
Uses: The US teaspoon is widely used in both culinary and non-culinary contexts across the United States. The US teaspoon is a commonly used unit in everyday cooking, especially in baking, where accurate measurements of ingredients like spices, extracts, and baking powder are key to getting consistent results. Outside the kitchen, this small but essential unit is frequently used in healthcare as a standard measure for liquid medications, particularly when dosing for children. While medical professionals usually recommend milliliters for precision, many over-the-counter medicines in the US still refer to teaspoons as a practical reference.
1 in³ = 3.324684 tsp
Let’s say you want to convert 100 in³ to tsp.
Using the formula:
100 × 3.324684 = 332.468 tsp
So, 100 in³ is approximately 332.468 tsp.
