## Default answer

Example with the default inputs (Cubic centimeters (cm³) 1): 1 cm³ = 0.004227 cups.

## Inputs

| Key | Label | Description |
| --- | --- | --- |
| value | Cubic centimeters (cm³) | The amount in cubic centimeters to convert. |
| result | Cups (cup) | The same amount in cups. |

## Outputs

| Key | Label | Description |
| --- | --- | --- |
| value | Cubic centimeters (cm³) | The amount in cubic centimeters to convert. |
| result | Cups (cup) | The amount in cups. |

## Method

cup = cm³ × 0.00422675283773 (the same as cm³ ÷ 236.5882365)

## Assumptions

- 1 cubic centimeter = 0.00422675283773 cups, from the exact definitions in NIST SP 811.
- Cups, ounces, tablespoons, teaspoons, pints, quarts, and gallons are US customary units: 1 US cup is 8 US fluid ounces.
- Exact on the typed decimals: at most 6 decimal places (6 significant digits below 0.0001), rounded half up.

## Worked examples

1. value = 1 gives result = 0.004227. Source: Exact unit definitions in NIST SP 811 (2008), Appendix B.8.
2. value = 188 gives result = 0.79463. Source: Exact unit definitions in NIST SP 811 (2008), Appendix B.8.
3. result = 0.79463 gives value = 188. Source: Exact unit definitions in NIST SP 811 (2008), Appendix B.8.

## FAQ

### How many cups are in a cubic centimeter?

1 cubic centimeter is 0.004227 cups, from the exact unit definitions (NIST SP 811).

### How do I convert cc to cups?

Multiply by 0.004227: cup = cm³ × 0.00422675283773 (the same as cm³ ÷ 236.5882365). For example, 1 cm³ × 0.004227 = 0.004227 cups.

### How do I convert cups back to cc?

Multiply by 236.588237, or type the cups into the second box and the converter works it out. 1 cup is 236.588237 cubic centimeters.

### What is 188 cc in cups?

188 ÷ 236.5882365 = 0.79463 US cup, just under 4/5 of a cup. Type 188 in the cc box to see it.

### Is a cc the same as a mL?

Yes. 1 cc (cubic centimeter, cm³) is exactly 1 mL, because a liter is 1,000 cm³ (NIST SP 811).

### Is this a US cup or a metric cup?

A US cup, 236.5882365 mL. A metric cup is 250 mL, so 188 cc is 188 ÷ 250 = 0.752 metric cup.
