760 mmHg is equal to 1013.25 hPa.
Table of Contents
The conversion from millimeters of mercury (mmHg) to hectopascals (hPa) is based on the pressure equivalence where 1 mmHg equals approximately 1.33322 hPa. Therefore, multiplying 760 mmHg by this factor gives the equivalent pressure in hPa units, which is the standard unit in meteorology and physics.

Conversion Formula
The formula to convert mmHg to hPa is:
hPa = mmHg × 1.33322
This works because 1 mmHg is defined as the pressure exerted by a 1 millimeter column of mercury at 0°C under standard gravity, which equals roughly 133.322 pascals (Pa). Since 1 hPa equals 100 Pa, the conversion factor becomes 1.33322.
Example calculation for 760 mmHg:
- Multiply 760 by 1.33322
- 760 × 1.33322 = 1013.247 hPa
- Rounded result is 1013.25 hPa
Conversion Example
- Convert 700 mmHg to hPa:
- 700 × 1.33322 = 933.254 hPa
- So, 700 mmHg equals approximately 933.25 hPa
- Convert 745 mmHg to hPa:
- 745 × 1.33322 = 993.648 hPa
- Result is about 993.65 hPa
- Convert 780 mmHg to hPa:
- 780 × 1.33322 = 1040.912 hPa
- Rounded to 1040.91 hPa
- Convert 750 mmHg to hPa:
- 750 × 1.33322 = 999.915 hPa
- Approximately 999.92 hPa

Conversion Definitions
mmHg: Millimeters of mercury is a unit of pressure based on the height of mercury column that the pressure can support in a barometer. It is used in medicine and meteorology, representing the force exerted by mercury column at standard gravity, traditionally for blood pressure and atmospheric pressure measurements.
hPa: Hectopascal is a metric unit of pressure equivalent to 100 pascals. It is widely used in meteorology to express atmospheric pressure. HPa provides a convenient scale for weather data, with 1013.25 hPa being the average sea-level pressure on Earth, making it easier for comparing weather patterns.
Conversion FAQs
Why is 760 mmHg often considered standard atmospheric pressure?
760 mmHg equals the pressure exerted by a mercury column 760 millimeters high at 0°C under standard gravity, which corresponds to the average sea level atmospheric pressure. This value is conventionally used as a reference point in various scientific and industrial settings, such as calibrating instruments.
Can the conversion factor between mmHg and hPa vary?
The conversion factor 1.33322 is derived from physical constants and constants of mercury density and gravity, so it stays constant under standard conditions. However, slight variations may arise if pressure is measured at different temperatures or gravitational fields but are negligible in practical uses.
Is there a difference between hPa and millibar?
No, the hectopascal and millibar are equivalent units of pressure; both equal 100 pascals. HPa is preferred by meteorologists internationally, but millibar is still used in some regions like the US for weather reports.
Why use hPa instead of mmHg in weather reports?
Hectopascals fit better into the metric system, making calculations and comparisons simpler globally. Also, hPa relates directly to pascals, the SI unit for pressure, which is more universal than mmHg, a unit tied to mercury’s physical properties.
How precise is the conversion from mmHg to hPa?
The conversion is precise up to at least four decimal places for everyday use. Minor differences might appear due to rounding or measurement errors, but for practical purposes such as weather forecasting or medical readings, this precision is sufficient.
