This document contains a series of unit conversion problems between Celsius, Fahrenheit, Kelvin, and Rankine temperatures, as well as between bars, Pascals, pounds per square inch (PSI), millimeters of mercury (mmHg), and kilograms per square centimeter (kg/cm2) pressures. The student is asked to perform unit conversions between these various temperature and pressure units. Formulas are provided to enable the conversions between Celsius, Fahrenheit, Kelvin, and Rankine scales, as well as between bars, Pascals, PSI, mmHg, and kg/cm2 pressure units.
