Cubic centimeters to tablespoons (cm³ to tbsp) converter

What is a cubic centimeters to tablespoons converter?

A cubic centimeters to tablespoons converter is an online tool that translates a volume given in cubic centimeters (cm³) into US tablespoons (tbsp), and back again. The cubic centimeter is a metric unit of volume equal to a cube one centimeter on each side, and it is numerically identical to the milliliter (1 cm³ = 1 mL). The tablespoon, by contrast, is a customary cooking measure used in the United States, where one US tablespoon is defined as exactly 14.7868 cubic centimeters.

Because these two units belong to different measurement systems, recipes, lab notes, and medical dosing instructions often mix them. This converter removes the guesswork and gives an exact figure in either direction.

How it works

The conversion rests on a single fixed relationship: one US tablespoon equals 14.7868 cm³. To go from cubic centimeters to tablespoons you divide the volume by 14.7868; to go from tablespoons to cubic centimeters you multiply by 14.7868.

• cm³ to tbsp: divide the number of cubic centimeters by 14.7868.
• tbsp to cm³: multiply the number of tablespoons by 14.7868.

The tool performs both calculations automatically: edit either field and the other updates to match.

Formula

$\text{tbsp} = \frac{\text{cm}^3}{14.7868}$

$\text{cm}^3 = \text{tbsp} \times 14.7868$

Conversion table

The following table lists common cubic centimeter values and their equivalent in US tablespoons, plus the reverse direction.

Examples

Example 1: 1 cm³ to tablespoons

Divide 1 cubic centimeter by 14.7868:

$\frac{1}{14.7868} \approx 0.067628 \text{ tbsp}$

So 1 cm³ is about 0.067628 US tablespoons — just under a fifteenth of a tablespoon.

Example 2: 1 tablespoon to cubic centimeters

Multiply 1 tablespoon by 14.7868:

$1 \times 14.7868 = 14.7868 \text{ cm}^3$

One US tablespoon contains exactly 14.7868 cubic centimeters.

Example 3: 100 cm³ to tablespoons

Divide 100 cubic centimeters by 14.7868:

$\frac{100}{14.7868} \approx 6.7628 \text{ tbsp}$

A 100 cm³ portion is roughly 6.76 tablespoons — a touch under seven.

Example 4: 10 tablespoons to cubic centimeters

Multiply 10 tablespoons by 14.7868:

$10 \times 14.7868 = 147.868 \text{ cm}^3$

Ten US tablespoons equal 147.868 cubic centimeters.

Notes

• This converter uses the US tablespoon (14.7868 cm³). The metric tablespoon (15 cm³), the UK tablespoon (17.7582 cm³), and the Australian tablespoon (20 cm³) differ, so check which standard your recipe assumes.
• Cubic centimeters and milliliters are interchangeable: 1 cm³ = 1 mL exactly, so any cm³ figure here also reads directly in milliliters.
• For cooking, rounding to two decimal places of a tablespoon is usually precise enough; for medical or laboratory work, keep more significant figures.

Frequently asked questions

How many cubic centimeters are in one tablespoon?

One US tablespoon equals exactly 14.7868 cubic centimeters. To convert any number of tablespoons, multiply by 14.7868.

How many tablespoons are in 100 cm³?

100 cubic centimeters is approximately 6.7628 US tablespoons, found by dividing 100 by 14.7868.

Is a cubic centimeter the same as a milliliter?

Yes. One cubic centimeter equals one milliliter exactly (1 cm³ = 1 mL), so the values are always identical.

Which tablespoon does this converter use?

It uses the US tablespoon of 14.7868 cm³. If your recipe uses a metric tablespoon (15 cm³) or an Australian tablespoon (20 cm³), the result will differ slightly.

How do I convert tablespoons back to cubic centimeters?

Multiply the number of tablespoons by 14.7868. For example, 3 tablespoons equal 3 × 14.7868 = 44.36 cm³. You can also simply type a value into the tablespoons field of this converter.

Why is the result not a round number?

The US tablespoon (14.7868 cm³) is not a whole-number multiple of the cubic centimeter, so conversions rarely produce clean figures. Rounding to two or three decimals is usually sufficient for everyday use.
