Some of these sites use the metric system, (many wind turbines are made in Denmark). What we refer to as miles-per-hour, they refer to as meters per second. When we talk about feet, they talk about meters. Here are some examples:
| Feet | Meters | MPH (miles per hour) | M/S (meters per second) | |
| 1 | 0.3 | 1 | 0.45 | |
| 3.28 | 3 | 2.24 | 1 | |
| 270 | 82.3 | 10 | 4.47 |
