1. Megapascals (MPa) is a unit of pressure, also known as megapascals. 1Pa refers to the pressure generated by a force of 1N uniformly pressing on an area of 1 square meter. 1 megapascal=1000000 Pa, which can also be written as 1MPa=1000000 Pa.
2. One kilogram of pressure (usually referring to force) refers to the situation where one kilogram of force is applied on an area of one square meter. The unit of pressure is Pascal (Pa), where 1 Pascal is equal to 1 Newton per square meter.
And megapascals (MPa) are units of pressure, where 1 MPa=1000000 Pa.
3. So, if you have a force of 1 kilogram acting on an area of 1 square meter, you will get 100000 Pascals, which is 0.1 MPa.
1MP=1000KP=1000000Pa
Attention: pa=N/㎡
4. 1 atmospheric pressure equals 1 kilogram of pressure
1 standard air pressure=0.1MP=100000Pa (N/㎡)=10N/c ㎡
1 bar=1 standard atmospheric pressure
1 kilogram force pressure refers to the pressure exerted by a 1 kilogram object on the object it supports, which can also be understood as gravity.
1MPa=10 ^ 6N/㎡.
1MPa means a force of 1 Newton applied to an area of 1 square millimeter, resulting in a pressure of 1Kgf/c ㎡=0.1MPa=1bar
In engineering, we still use the unit of kilogram force, so we can obtain the engineering atmospheric pressure
1 kilogram of force is equivalent to 9.8 Newton
1 engineering atmospheric pressure=1 atmosphere=1Kgf/c ㎡=0.1MPa=1bar
Note: The international unit of pressure is Pascal (Pa). Due to the small size of Pascal, which is not easy to calculate, we often use MPa (megapascal). One sunflower seed placed on a table has about 10 pascals, so megapascals are also commonly used units in China.
