The imperial teaspoon is a unit of volume used primarily in the United Kingdom and other countries that once followed the imperial measurement system. It's slightly smaller than the US teaspoon, with one imperial teaspoon equal to 4.7355 milliliters. This unit is abbreviated as tsp and has historically appeared in older British cookbooks and kitchenware.
While the imperial system has been largely replaced by the metric system in the UK, many traditional recipes and household items still reference the imperial teaspoon. It's part of a broader set of imperial volume measurements, including tablespoons, fluid ounces, and pints.
Uses: The imperial teaspoon was once a standard unit in British kitchens, used to measure ingredients like sugar, baking powder, and liquid extracts. Though the UK officially uses the metric system today, imperial units still appear in everyday cooking, particularly in family recipes passed down through generations.
You may also see the imperial teaspoon referenced in medication dosages or on packaging in regions that retain imperial labeling. While modern measuring tools often default to metric or US volumes, the imperial teaspoon remains relevant for those following traditional British cooking or converting older recipes accurately.
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.
1 tsp (imp) = 0.361223 in³
Let’s say you want to convert 100 tsp (imp) to in³.
Using the formula:
100 × 0.361223 = 36.122 in³
So, 100 tsp (imp) is approximately 36.122 in³.
