Do a quick conversion: 1 megapascals = 1 newtons/square millimeter using the online calculator for metric conversions. Check the chart for more details.
• Between B and C (specimen 3), the deformation becomes localised (“necking”), leading to failure at point C. Standard mechanical properties R e = yield stress, yield strength or yield point, in MPa or N/mm2, corresponding to the end of the elastic region (point A in the diagram) R m = ultimate tensile strength, in MPa or

How many N/mm² make 1 Megapascal? Measurement calculator that can be used to convert MPa to N/mm² (Megapascal to Newton per Square millimeter), among others. (Pressure)
Therefore, 1,000,000 Pa (pascal) equals 1 MPa. MPa can be expressed in an equivalent form as N/mm² (newton per square milimiter): 1 MPa = 1 N/mm². The unit of MPa is well adapted to conveniently indicate stress and strength of common construction materials.
The dimension of stress is the same as that of pressure, and therefore the SI unit for stress is the pascal (Pa), which is equivalent to one newton per square meter (N/m²). In Imperial units, stress can be measured in pound-force per square inch, which is abbreviated as psi.
1 MPa (megapascal) is exactly equal to 1 N/mm2 (Newton per square millimetre) 1 kN/mm² = 1000 N/mm². Therefore 1 MPa = 1 kN/mm²/1000 = 0.001 kN/mm². The megapascal is a x1000000 multiple of the pascal unit which is the SI unit for pressure. 1 megapascal equals 1,000,000 pascals.
