## Default answer

Example with the default inputs (Kilograms (kg) 5.6): 5.6 kg = 5,600 g.

## Inputs

| Key | Label | Description |
| --- | --- | --- |
| value | Kilograms (kg) | The amount in kilograms to convert. |
| result | Grams (g) | The same amount in grams. |

## Outputs

| Key | Label | Description |
| --- | --- | --- |
| value | Kilograms (kg) | The amount in kilograms to convert. |
| result | Grams (g) | The amount in grams. |

## Method

g = kg × 1000 (the same as kg ÷ 0.001)

## Assumptions

- 1 kilogram = 1000 grams, from the exact definitions in NIST SP 811.
- Exact on the typed decimals: at most 6 decimal places (6 significant digits below 0.0001), rounded half up; an answer of 1 billion or more shows at most 15 significant digits.

## Worked examples

1. value = 1 gives result = 1,000. Source: Exact unit definitions in NIST SP 811 (2008), Appendix B.8.
2. value = 2.5 gives result = 2,500. Source: Exact unit definitions in NIST SP 811 (2008), Appendix B.8.
3. result = 2,500 gives value = 2.5. Source: Exact unit definitions in NIST SP 811 (2008), Appendix B.8.
