Our mmHg to atm converter allows you to easily convert pressure values between millimeters of mercury (mmHg) and atmospheres (atm). Simply enter your value, and the tool will provide an instant and accurate conversion.
How to Convert mmHg to atm
The conversion between mmHg and atm is based on the following formula:
Pressure in atm = Pressure in mmHg ÷ 760
Pressure in mmHg = Pressure in atm × 760

The Basics of the two Pressure units
What is mmHg?
Millimeters of mercury (mmHg) is a unit of pressure measurement commonly used in meteorology, aviation, and medicine (e.g., blood pressure readings). It represents the pressure exerted by a 1-mm column of mercury.
What is atm?
Atmosphere (atm) is a standard unit of pressure. One atmosphere is the pressure exerted by the Earth’s atmosphere at sea level, which is defined as 1 atm = 760 mmHg.
Why Use This mmHg to atm Converter?
- Fast & Accurate: Instant and precise conversion based on standard values.
- User-Friendly Interface: Simple input and output for hassle-free calculations.
- Useful in Various Fields: Ideal for science, medicine, weather analysis, and engineering applications.
Frequently Asked Questions (FAQs)
1. How many mmHg are in 1 atm?
1 atm is equal to 760 mmHg.
2. How do you convert mmHg to atm?
Use the formula: Pressure in atm = Pressure in mmHg ÷ 760. For example, 760 mmHg ÷ 760 = 1 atm.
3. How do you convert atm to mmHg?
Multiply the pressure in atmospheres by 760: Pressure in mmHg = Pressure in atm × 760. For example, 2 atm × 760 = 1520 mmHg.
4. What is normal atmospheric pressure in mmHg?
Standard atmospheric pressure at sea level is 760 mmHg or 1 atm.
5. Where is mmHg commonly used?
mmHg is widely used in medical fields (blood pressure measurement), aviation, meteorology, and chemistry.
