**How to convert 743 mmHg to atm (Unit converter)**

To convert 743 mmHg to atm (millimeters of mercury to atmospheres), divide the 743 by 760. Alternatively, you can multiply mmHg by 0.0013157894736842 to find the atm value. Both approaches will give you the correct solution.

**mmHg to atmospheres conversion formula**

To convert mmHg (millimeters of mercury) to atm (atmospheres), use the following conversion formula:

atm = mmHg x 0.0013157894736842

For example, if you have 743 mmHg, then the equivalent in atm would be:

atm = 743 mmHg x 0.0013157894736842/mmHg = 0.977632 atm

**Conversion formula example (Millimeters of mercury to standard atmospheres)**

Suppose we have a pressure reading of 743 mmHg. How do we find out how much that is in atmospheres (atm) using the conversion formula?

To convert 743 mmHg to atm, divide the pressure in mmHg by 760. This approach gives you the answer in atm, which is 0.977632 atm.

**Quick conversion chart: mmHg to atm [0 °C] conversion table**

One popular method to convert mmHg to atm without needing to calculate the answer yourself is to use our conversion chart. Conversion charts, also called conversion tables, list millimeters of mercury (mmHg) in one column with the corresponding number of standard atmospheres (atm) in the second column.

For example, to convert 743 mmHg to atm using our conversion chart, locate the entry for 743 mmHg in the first column and note that the matching value for atm in the second column is 0.977632. There is 0.977632 atm in 743 mmHg.

**Definition: What is mmHg? (Unit of measurement)**

Millimeters of mercury (symbol = mmHg) is a manometric unit of pressure equal to the pressure exerted by a column of mercury that is one millimeter high under standard gravity. You will most frequently see mmHg used to measure blood pressure or in weather reports from meteorologists.

The mmHg unit is commonly used in medicine (blood pressure), meteorology (weather reports), aviation (cabin pressure), and other scientific fields.

1 mmHg is equal to 1/760 standard atmospheres (atm) or, in SI units, 133.322 Pa (Pascals).

**Definition: What is standard atmosphere (atm)?**

Standard atmosphere (symbol = atm) is a unit of pressure defined as 101,325 Pa, 760 mmHg, 101.325 kPa, 1.01325 bar, 760 torr, 4.6959 psi, or 1 ata (atmosphere absolute). Standard atmospheric pressure is equivalent to the average atmospheric pressure on Earth at sea level.

It is called a ‘standard atmosphere’ because it is sometimes used as a standard or reference pressure.

**Is mmHg equal to atm?**

No, mmHg is not equal to atm. One atmosphere is equivalent to 760 mmHg, while one mmHg equals 0.00131579 atmospheres.

**How many mmHg are in 1 atm?**

There are 760 mmHg in 1 atm.

**How do you convert blood pressure to atm? (Pressure conversions)**

To convert blood pressure from mmHg to atm, multiply the mmHg value by 0.0013157894736842, which is the mmHg to atm conversion factor.

**How to convert mmHg to kPa **

To convert mmHg to atm, multiply the mmHg value by 0.133322387415.

For example, to convert 743 mmHg to kPa, multiply 743 by 0.133322387415. The resulting answer is 99.0585 kPa.

**How many kPa are in 1 mmHg? **

There are 0.133322387415 kPa in 1 mmHg.

**How many mmHg are in 1 torr?**

There are 0.9999998575337 mmHg in 1 torr. While torr and mmHg are nearly equivalent, there is a difference of 0.000015% when making a unit conversion. While this is a slight difference, you should account for calculations and conversions requiring precision.

**What is atmospheric pressure at sea level?**

Atmospheric pressure at sea level is 760 millimeters of mercury (mmHg), 1013.25 millibars (mb), or 101325 pascals (Pa). This means that the sea-level atmosphere exerts 760 mmHg of force on every square meter of surface area.

As elevation increases, atmospheric mass decreases, which means that atmospheric pressure decreases with increasing elevation.

**Conclusion**

In conclusion, 743 mmHg equals 0.977632 atm.
