Mpa stands for megapascal. One megapascal equals 1,000,000 pascals. The pascal is the standard metric system unit of measure for pressure, defined as one newton of force per square meter. N/mm2 stands for newton per square millimetre. One newton per square millimetre equals 1,000,000 newtons per square meter, or N/m2. One newton per square meter equals one pascal. Use this information to convert an mpa value to an N/mm2 value.

Turn on your calculator and enter the megapascal value.

Divide the megapascal value by 1,000,000 to reach the pascal value, which equals the newton per square meter value.

Multiply the newton per square meter value by 1,000,000 to get the newton per square millimetre value. You should arrive at your original megapascal value. Thus, one megapascal equals one newton per square millimetre.
