压力是垂直于每个单位区域表面施加的力。它是在pascal（PA）中测量的。
1 hPa = 1 mbar
1 mbar = 1 hPa
例子:
将15 海毛转换为中间的：
15 hPa = 15 mbar
| 海毛 | 中间的 |
|---|---|
| 0.01 hPa | 0.01 mbar |
| 0.1 hPa | 0.1 mbar |
| 1 hPa | 1 mbar |
| 2 hPa | 2 mbar |
| 3 hPa | 3 mbar |
| 5 hPa | 5 mbar |
| 10 hPa | 10 mbar |
| 20 hPa | 20 mbar |
| 30 hPa | 30 mbar |
| 40 hPa | 40 mbar |
| 50 hPa | 50 mbar |
| 60 hPa | 60 mbar |
| 70 hPa | 70 mbar |
| 80 hPa | 80 mbar |
| 90 hPa | 90 mbar |
| 100 hPa | 100 mbar |
| 250 hPa | 250 mbar |
| 500 hPa | 500 mbar |
| 750 hPa | 750 mbar |
| 1000 hPa | 1,000 mbar |
| 10000 hPa | 10,000 mbar |
| 100000 hPa | 100,000 mbar |
