Why is the atmospheric pressure measured at sea level? Why is the atmospheric pressure not felt by us?

Explanation

### Step-by-Step Solution

**Step 1: Understanding Atmospheric Pressure Measurement at Sea Level**
- Atmospheric pressure is measured at sea level because sea level provides a consistent reference point.
- Sea level is approximately the same all over the world, making it a universal standard for measuring atmospheric pressure.

**Step 2: Importance of Consistent Reference**
- By using sea level as a reference, we can compare atmospheric pressure readings taken at different elevations.
