Shanghai Hongyi Pressure GaugeThe conversion methods for range units mainly include the conversion between Pascal (Pa), Kilopascal (kPa), and Megapascal (MPa).

In China and the International System of Units, the unit of pressure is Pascal (Pa), but due to the small value of Pa, kilopascals (kPa) and megapascals (MPa) are commonly used as units of pressure in practical applications. The specific conversion relationship is as follows:

1MPa = 1000kPa = 1000000Pa

1kPa = 0.001MPa = 1000Pa ‌

In addition, pressure units can also be converted to other non SI units, such as engineering atmospheric pressure (kgf/cm2), millimeters of mercury (mmHg), and millimeters of water column (mmH2O). But these conversion relationships are relatively complex and rare in daily use. For the common conversion between kPa and MPa, simply remember the simple conversion relationship mentioned above to perform a quick conversion. For example, if the reading of the kPa pressure gauge is 500, dividing it by 1000 will give the corresponding MPa value, which is 0.5 MPa
