Understanding the relationship between mmHG and Pa is crucial for various fields, including medicine, meteorology, and engineering. This article provides a comprehensive guide to converting mmHG to Pa, exploring its applications and offering practical tips and tricks.

Understanding mmHG and Pa
- mmHG (millimeters of mercury): A unit of pressure denoting the force exerted by a column of mercury 1 mm high.
- Pa (Pascals): The SI unit of pressure, defined as the force of 1 newton acting on a surface area of 1 square meter.
Conversion Formula
The conversion between mmHG and Pa is straightforward:
1 mmHG = 133.322 Pa
To convert mmHG to Pa, simply multiply the mmHG value by 133.322.
Applications of mmHG to Pa Conversion
