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 = 100 Pa
1 Pa = 0.01 hPa
例子:
将15 海毛转换为仪表压力：
15 hPa = 1,500 Pa
| 海毛 | 仪表压力 |
|---|---|
| 0.01 hPa | 1 Pa |
| 0.1 hPa | 10 Pa |
| 1 hPa | 100 Pa |
| 2 hPa | 200 Pa |
| 3 hPa | 300 Pa |
| 5 hPa | 500 Pa |
| 10 hPa | 1,000 Pa |
| 20 hPa | 2,000 Pa |
| 30 hPa | 3,000 Pa |
| 40 hPa | 4,000 Pa |
| 50 hPa | 5,000 Pa |
| 60 hPa | 6,000 Pa |
| 70 hPa | 7,000 Pa |
| 80 hPa | 8,000 Pa |
| 90 hPa | 9,000 Pa |
| 100 hPa | 10,000 Pa |
| 250 hPa | 25,000 Pa |
| 500 hPa | 50,000 Pa |
| 750 hPa | 75,000 Pa |
| 1000 hPa | 100,000 Pa |
| 10000 hPa | 1,000,000 Pa |
| 100000 hPa | 10,000,000 Pa |
