Length
Convert foot (ft) to yard (yd). Length units span pipe diameters (mm, inch), plant dimensions (m, ft), and roughness (µm) — mixing metric and imperial is routine.
1 ft = 0.3333333 yd
To convert foot to yard, multiply the ft value by 0.3333333. To go the other way, divide by 0.3333333 (or multiply by 3).
| ft | yd |
|---|---|
| 1 | 0.3333333 |
| 2 | 0.6666667 |
| 5 | 1.666667 |
| 10 | 3.333333 |
| 25 | 8.333333 |
| 50 | 16.66667 |
| 100 | 33.33333 |
| 250 | 83.33333 |
| 500 | 166.6667 |
| 1000 | 333.3333 |
Pipe sizes are labelled in inches (NPS) but calculated in mm; equipment layouts mix metres and feet.
Velocity scales with the inverse square of diameter, so a small length error compounds quickly in flow calculations.
Worked example. A length of 0.328084 ft is 0.1093613 yd.
Multiply the value in ft by 0.3333333 to get yd. For example, 10 ft = 3.333333 yd.
1 ft equals 0.3333333 yd.
