About Teaspoon to Cubic Centimeter Conversion

Converting teaspoon to cubic centimeter comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using cubic centimeter, or a laboratory protocol may specify volumes in teaspoon that need to be measured with equipment calibrated in cubic centimeter.

In everyday use, knowing that 5 tsp = 24.64 cm³ and 10 tsp = 49.29 cm³ covers most common situations. For bulk calculations, 100 tsp = 492.9 cm³ is a useful anchor. The reverse conversion — cubic centimeter back to teaspoon — uses the factor 0.2029, so 1 cm³ = 0.2029 tsp.

All conversions use the internationally recognized factor of exactly 1 tsp = 4.929 cm³. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.

Quick Answer

Formula: Cubic Centimeter = Teaspoon × 4.92892

Multiply any teaspoon value by 4.92892 to get cubic centimeter. One teaspoon equals 4.92892 cm³.

Reverse: Teaspoon = Cubic Centimeter × 0.2028842

Worked Examples

One teaspoon
1 tsp × 4.92892 = 4.92892 cm³
1 tsp = 4.929 cm³.
One tablespoon
3 tsp × 4.92892 = 14.78676 cm³
3 tsp = 14.79 cm³ = 1 tablespoon.
One US cup
48 tsp × 4.92892 = 236.58816 cm³
48 tsp = 236.6 cm³ = 1 cup.
One fl oz (approx)
6 tsp × 4.92892 = 29.57352 cm³
6 tsp = 29.6 cm³ ≈ 1 fl oz.

Frequently Asked Questions

About Teaspoon and Cubic Centimeter

Teaspoon (tsp)

The US teaspoon is exactly one-third of a tablespoon, 4.92892 mL. It was standardized in the US in the early 20th century partly to address inconsistent home medication dosing.

Teaspoons are the smallest standard cooking measure in the US system, used for spices, leaveners, and flavorings. A medical teaspoon dose conventionally means 5 mL.

Interesting fact: The teaspoon is behind one of science's most cited comparisons: the entire Pacific Ocean would fill roughly 7.1 × 10²³ teaspoons.

Cubic Centimeter (cm³)

The cubic centimeter (also cc or mL) is the volume of a cube measuring 1 cm on each side. It has been part of the CGS system since the 19th century, formalized by the British Association for the Advancement of Science in 1874.

In medicine and pharmacy, the cc is the preferred volume notation for injection doses, IV drips, and surgical implants. Automotive engineers use cc to express engine displacement.

Interesting fact: Because 1 mL = 1 cm³ exactly, the units are fully interchangeable — medical staff say 'cc' while chemists say 'mL'.
