Convert Cubic centimetres to US teaspoons
1 cubic centimetre is 0.2 tsp. One cubic centimetre is exactly 0.202884136211 US teaspoons.
One cubic centimetre is 0.20288414 US teaspoons. To convert cubic centimetres to US teaspoons, multiply by 0.20288414; to go the other way, divide by 0.20288414 or multiply by 4.9289216. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 130. A thousandth of a litre, which makes it exactly a millilitre — the same volume under two names.

What is a cubic centimetre?
A thousandth of a litre, which makes it exactly a millilitre — the same volume under two names. Engine displacement uses cc and medicine uses ml for the identical quantity.
What is a US teaspoon?
One third of a tablespoon, about 4.93 ml. A metric teaspoon is a round 5 ml, which is why recipes rarely notice the difference.
How many US teaspoons are in a cubic centimetre?
One cubic centimetre is 0.20288414 US teaspoons. Going the other way, one US teaspoon is 4.9289216 cubic centimetres. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
