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 = 0 MPa
1 MPa = 10,000 hPa
例子:
将15 海毛转换为巨质：
15 hPa = 0.002 MPa
| 海毛 | 巨质 |
|---|---|
| 0.01 hPa | 1.0000e-6 MPa |
| 0.1 hPa | 1.0000e-5 MPa |
| 1 hPa | 0 MPa |
| 2 hPa | 0 MPa |
| 3 hPa | 0 MPa |
| 5 hPa | 0.001 MPa |
| 10 hPa | 0.001 MPa |
| 20 hPa | 0.002 MPa |
| 30 hPa | 0.003 MPa |
| 40 hPa | 0.004 MPa |
| 50 hPa | 0.005 MPa |
| 60 hPa | 0.006 MPa |
| 70 hPa | 0.007 MPa |
| 80 hPa | 0.008 MPa |
| 90 hPa | 0.009 MPa |
| 100 hPa | 0.01 MPa |
| 250 hPa | 0.025 MPa |
| 500 hPa | 0.05 MPa |
| 750 hPa | 0.075 MPa |
| 1000 hPa | 0.1 MPa |
| 10000 hPa | 1 MPa |
| 100000 hPa | 10 MPa |
