🔍 Key Concepts

• Standard units used on traditional marine barometers in the U.S. versus metric units • The difference between millibars, millimeters of mercury, and inches of mercury • What an aneroid barometer dial usually looks like and how it is labeled

💭 Think About

• First, think about what a normal sea-level atmospheric pressure value is, and in which units you usually see a value around 30. • Look at each choice and ask: would 30.05 be a realistic number in that unit for everyday atmospheric pressure? • Consider whether a single reading on the dial can, by itself, tell you if the pressure is rising or falling.

✅ Before You Answer

• Know that standard sea-level pressure is about 1013 in one common metric unit and about 29.92 in a common imperial unit. • Remember that millimeters of mercury numbers are much larger (hundreds) for normal pressure, not around 30. • Confirm whether a barometer’s pointer position alone indicates trend (rising/falling) or just the instantaneous value.
