Why Barometers Have Two Scales

Barometers have two scales because they can measure atmospheric pressure using either the metric system or inches of mercury. The metric scale is used in countries that have adopted the metric system, while the inches of mercury scale is used in countries that still use the imperial system. This dual scale system allows barometers to be used universally, regardless of the measurement system used in a particular region.
