- Miles mi are a imperial unit used for measuring length
- Yards yd are a imperial unit used for measuring length
- Feet (ft) are an imperial unit used for measuring length
- Hence, ft, yd, and mi are imperial units used for measuring length

- Ft, yd, and mi are imperial units used for measuring length
- Imperial units are not metric units
- So, ft, yd, and mi are not metric units

Therefore, ft, yd, and mi are not metric units
