What is the value of atmospheric pressure at sea level?

• A. 29.9 psi
• B. 14.7 psi
• C. 1013.25 hPa
• D. 760 mmHg

Answer: (B)

The value of atmospheric pressure at sea level is 14.7 psi, which is a standard pressure measurement used in various scientific and engineering applications. This value is equivalent to the average atmospheric pressure that exerts a force of 14.7 pounds per square inch on a surface at sea level under typical conditions. Understanding the relevance of this measurement is essential for calibration technicians, as it serves as a baseline for many atmospheric tests and calibration processes. It’s important to note that this value may fluctuate slightly due to weather changes, but the accepted average remains at 14.7 psi in standard atmospheric conditions. In addition to psi, atmospheric pressure can also be expressed in other units, such as hPa (hectopascals) and mmHg (millimeters of mercury). However, in specific contexts, such as safety or engineering applications, psi is often more commonly referenced, making it crucial for technicians to be familiar with this value as a primary reference point for pressure measurements.
