Conversion Formula
The formula to convert kpa to mmhg is: mmhg = kpa * 7.50062. This works because 1 kpa equals approximately 7.50062 mmhg. By multiplying the pressure in kpa by this factor, the value in mmhg is obtained. For example, 20 kpa times 7.50062 equals 150.0124 mmhg, which rounds to 150.02 mmhg.
Conversion Example
- Convert 10 kpa to mmhg:
- Step 1: Write the formula: mmhg = 10 * 7.50062
- Step 2: Multiply: 10 * 7.50062 = 75.0062
- Step 3: Round to four decimal places: 75.0062 mmhg
- Convert 35 kpa to mmhg:
- Step 1: Formula: mmhg = 35 * 7.50062
- Step 2: Multiply: 35 * 7.50062 = 262.5217
- Step 3: Rounded: 262.5217 mmhg
- Convert 5 kpa to mmhg:
- Step 1: Formula: mmhg = 5 * 7.50062
- Step 2: Multiply: 5 * 7.50062 = 37.5031
- Step 3: Rounded: 37.5031 mmhg

Conversion Definitions
kpa
Kilopascal (kpa) is a metric unit measuring pressure, where 1 kpa equals 1,000 pascals. It is used in science and engineering to quantify force per unit area, such as in weather reports or hydraulic systems, representing the strength of a pressure applied over a surface.
mmhg
Millimeters of mercury (mmhg) is a pressure unit based on the height of a mercury column, historically used in blood pressure and barometric measurements. 1 mmhg equals the pressure exerted by a 1-millimeter column of mercury at standard gravity.
Conversion FAQs
How accurate is converting 20 kpa to mmhg using the formula?
The conversion using the factor 7.50062 provides a high degree of precision for pressure measurements, suitable for most practical applications. Minor variations may occur due to rounding, but for standard purposes, the result is accurate enough.
Can the conversion factor change depending on temperature or altitude?
The factor 7.50062 is constant because it is based on the physical properties of mercury and standard gravity. However, environmental conditions like temperature and altitude do not change the conversion factor but may affect pressure readings in real-world measurements.
What should I do if my pressure measurement is in psi and I need mmhg?
First, convert psi to kpa (multiply by 6.89476), then convert kpa to mmhg (multiply by 7.50062). Combining these steps allows you to get mmhg from psi accurately without direct conversion.
