How to Convert Teaspoons to Cubic centimetres (tsp to cm³)
Volume conversions help with baking from American recipes, comparing petrol prices quoted per gallon abroad with pump prices per litre here, and reading PUB water bills in cubic metres. This guide shows how to convert teaspoons into cubic centimetres by hand, with examples and a quick-reference table.
The conversion
To convert teaspoons to cubic centimetres, multiply the value by 4.92892. To go the other way, divide by the same number (or multiply by 0.2028842018). For a quick estimate, multiply by about 4.9.
Cubic centimetres = teaspoons × 4.92892
Worked examples
- 3 tsp = 14.7868 cm³
- 12.5 tsp = 61.6115 cm³
- 75 tsp = 369.669 cm³

Is tsp to cm³ exact?
The factors used here are the internationally defined values where they exist; results are rounded for display only.

Mistakes to avoid
Rounding the factor too early
Using 3 instead of 3.28 for feet per metre introduces an error of almost 9% before you have started.
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
Dropping the units
A bare number without a unit is easy to misread later. Always write the unit with the result.
Background
Many conversion factors are exact by definition. The inch has been defined as exactly 2.54 centimetres since 1959, and the pound as exactly 0.45359237 kilograms, so conversions involving them can be as precise as you need.
Unit conversion is simply multiplication by a fixed ratio. The ratio between two units of the same quantity never changes, so once you know it you can convert any value in either direction.
For everyday use, three or four significant figures are usually enough. Engineering, science and trade documents may need more, and rounding should happen only at the end of a calculation.
