Microns to Inches of Mercury: From Medical to Measurement

Microns and inches of mercury (inHg) are two different units of pressure measurement, with microns being a unit of length. Microns are often used to measure the pressure in medical applications, while inHg is commonly used in barometric applications. Inches of mercury are named after the manometer, which was attached to a vertical tube with one end open to the atmosphere. The atmospheric pressure causes the liquid column to rise in the tube until its weight balances the force of gravity. The number of inches the liquid rises is proportional to the pressure, hence the name inches of mercury.

Microns to Inches of Mercury Conversion

1 micron of mercury (µmHg) is equal to 0.0004433 inHg. To convert microns of mercury to inches of mercury, multiply the value in microns by 0.0004433.

Formula:

inHg = µmHg x 0.0004433

Medical Applications of Microns of Mercury

Microns of mercury are commonly used in medical applications to measure pressure. For example, the pressure in the lungs is often measured in microns of mercury. A pressure of 100 µmHg is considered normal, while a pressure below 80 µmHg may indicate a problem.

Barometric Applications of Inches of Mercury

Inches of mercury are commonly used in barometric applications to measure atmospheric pressure. The standard atmospheric pressure at sea level is 29.92 inHg. A pressure above 30 inHg is considered high, while a pressure below 29 inHg is considered low.

Common Mistakes to Avoid

When converting microns of mercury to inches of mercury, it is important to avoid the following mistakes:

• Confusing microns with micrometers. Micrometers are 1,000 times larger than microns.
• Using the wrong conversion factor. The conversion factor from microns of mercury to inches of mercury is 0.0004433.
• Forgetting to round the answer to the nearest hundredth.

Applications of Microns and Inches of Mercury

Microns of mercury and inches of mercury have a wide range of applications, including:

• Medical applications: Measuring pressure in the lungs, heart, and other organs
• Barometric applications: Measuring atmospheric pressure
• Industrial applications: Measuring pressure in pipelines and other industrial processes
• Scientific applications: Measuring pressure in research experiments
