Altimeter Setting
A precise tool.
What is the Altimeter Setting & How does it work?
An altimeter is an instrument used to measure altitude above sea level. It works by measuring the atmospheric pressure, which decreases with increasing altitude.
P = P_0 \cdot e^{-\frac{gMh}{RT}}
P = pressure at altitude h, P_0 = sea level pressure, g = acceleration due to gravity, M = molar mass of air, R = universal gas constant, T = temperature
Altimeter settings are typically given in either hectopascals (hPa) or inches of mercury (inHg). Converting between these units is essential for accurate altitude readings.
