As in IS 456: 1964 and IS 456: 1978 it is noted that 1 N/mm 2 = 10 kg/cm 2. ∴ M 10, M 15, etc grades of concrete of IS 456: 2000 corresponds to M 100, M 150 grades of concrete respectively of IS 456:1964. According to IS code: Bond stress for M20 grade concrete is 1.2 N/mm 2 or 12 kg/cm 2. ∴ For M15 it will be 1.0 N/mm 2 or 10 kg/cm 2.

Kilogram or Kilogram Force per Square Centimeter (kg/cm2 or kgf/cm2) is a pressure unit that has been largely superseded by the SI unit system of pascal units. It is the metric equivalent of pounds per square inch (psi). 1 kg/cm2 equals 98,066.5 pascals. Similarly to psi, kg/cm2 is part of a group of pressure units that relate pressure with weight.
