What does inch mercury (32°F) measure?

Inch mercury (32°F) is a pressure unit that represents the pressure from a one-inch column of mercury at 32°F under standard gravity.

Why is hectopascal used in meteorology?

Hectopascal is a metric pressure unit equal to 100 pascals and is widely employed in meteorology for expressing air pressure and weather forecasting.

Can this converter be used for aviation purposes?

Yes, converting inch mercury to hectopascal aids in setting altimeters and planning flights where metric units are standard.
