速度是相对于参考框架的对象位置的变化速率。它以每次距离的单位（例如每秒米（m/s））进行测量。
1 km/s = 1,000,000,000 µm/s
1 µm/s = 1.0000e-9 km/s
例子:
将15 每秒公里转换为每秒千分尺：
15 km/s = 15,000,000,000 µm/s
| 每秒公里 | 每秒千分尺 |
|---|---|
| 0.01 km/s | 10,000,000 µm/s |
| 0.1 km/s | 100,000,000 µm/s |
| 1 km/s | 1,000,000,000 µm/s |
| 2 km/s | 2,000,000,000 µm/s |
| 3 km/s | 3,000,000,000 µm/s |
| 5 km/s | 5,000,000,000 µm/s |

| 20 km/s | 20,000,000,000 µm/s |
| 30 km/s | 30,000,000,000 µm/s |
| 40 km/s | 40,000,000,000 µm/s |
| 50 km/s | 50,000,000,000 µm/s |
