Chapter 5 Measurement 89 To convert millibar (mb) to kilogram/centimeter squared (kg/cm2), m the conversion chart shows a multiplier of 0.00102. To convert 75 mb to kg/cm2, the calculation would be as shown. 75 mb × 0.00102 = 0.07650 kg/cm2 Thus, 75 mb equals 0.0765 kg/cm2. To convert kg/cm2 to mb, the chart shows a multiplier of 980.7. 0.0765 kg/cm2 × 980.7 = 75.02355 mb Thus, 0.0765 kg/cm2 equals 75.02355 mb, which can be rounded off to 75 mb.

A conversion of 85 psi to kg/cm2 would be arranged as shown here. 85 psi × 0.07031 = 5.97635 kg/cm2 Thus, 85 psi equals 5.97635 kg/cm2, which could be rounded off to 5.98 kg/cm2 or 6 kg/cm2. To convert 5.98 kg/cm2 to psi, use the multiplier 14.22. 5.98 kg/cm2 × 14.22 = 85.0356 psi Thus, 5.98 kg/cm2 equals 85.0356 psi, which can be rounded off to 85 psi. 5
