Note : Underlined values are exact.
- The SI metric system is based on the international system of units.
- In some circumstances the term "weight" is used as meaning force and, therefore, it would have the units of force i.e. N(newtons). It is a more common practice to associate "Weight" with mass when it would have units of mass. I.e. kg (kilograms).
- Properly, stress is expressed in pascals (PA) or N/m2. However, M pascals or n/mm2 is commonly used.
- It is convert kgf/ mm2 to MPA (N/ mm2), multiply by 9.80665.
