## Barometric Pressure Conversion Exercise

A weather reporter on TV reports the barometer pressure as 28.7 inches of mercury. Calculate this pressure in the following units:

a. Pressure = ______ atm

b. Pressure = ______ torr

c. Pressure = ______ psi

d. Pressure = ______ bars

---

To complete this exercise, students will need to use the appropriate conversion factors to convert the given pressure from inches of mercury (inHg) to atmospheres (atm), torr, pounds per square inch (psi), and bars. The conversion factors are as follows:

- **1 atm = 29.92 inches of mercury**
- **1 atm = 760 torr**
- **1 atm = 14.696 psi**
- **1 atm = 1.01325 bar**

Use these factors to find the values in each unit.
