## Default answer

Example with the default inputs (Feet (ft) 1): 1 ft = 0.333333 yd.

## Inputs

| Key | Label | Description |
| --- | --- | --- |
| value | Feet (ft) | The amount in feet to convert. |
| result | Yards (yd) | The same amount in yards. |

## Outputs

| Key | Label | Description |
| --- | --- | --- |
| value | Feet (ft) | The amount in feet to convert. |
| result | Yards (yd) | The amount in yards. |

## Method

yd = ft × 0.333333333333 (the same as ft ÷ 3)

## Assumptions

- 1 foot = 0.333333333333 yards, 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 = 0.333333. Source: Exact unit definitions in NIST SP 811 (2008), Appendix B.8.

## FAQ

### How many yards are in a foot?

1 foot is 0.333333 yards, from the exact unit definitions (NIST SP 811).

### How do I convert feet to yards?

Multiply by 0.333333: yd = ft × 0.333333333333 (the same as ft ÷ 3). For example, 1 ft × 0.333333 = 0.333333 yd.

### How do I convert yards back to feet?

Multiply by 3, or type the yards into the second box and the converter works it out. 1 yard is 3 feet.

### What is 100 feet in yards?

33.333333 yd: 100 ÷ 3. A yard is 3 feet of 0.3048 m, so a yard is 3 × 0.3048 = 0.9144 m exactly (NIST SP 811).
