🔍 Key Concepts

• Standard atmospheric pressure is often given in several different units, including inches of mercury (inHg), millibars (mb or hPa), and millimeters of mercury (mmHg). • Think about the value commonly used in aviation altimeters and marine barometers for sea level standard pressure. • Know the approximate equivalence: 1 atmosphere ≈ 1013.25 mb ≈ 760 mmHg ≈ ? inHg.

💭 Think About

• Which of the answer choices looks like a value you would expect for inches of mercury on a barometer at sea level? Typical everyday readings are a little above or below this number. • Two of the options actually match standard pressure, but in different units. Can you match each number to its correct unit (inHg, mb/hPa, or mmHg)? • Eliminate any values that are clearly too large to be a realistic barometer reading in inches (think: normal readings are in the 20–31 range).

✅ Before You Answer

• Identify which choice is in the 20–31 range, which is realistic for inHg sea-level pressure readings. • Recognize that 1013.2 is a familiar number in millibars/hectopascals, and 760 is familiar in millimeters of mercury (mmHg), not inches. • Confirm that you are choosing the value that matches the inHg unit, not just any standard sea-level pressure value.
