What is kPa in measuring blood pressure?
Elevated blood pressure values are a systolic pressure equal to or greater than 160 mmHg (21.3 kPa) and/or a diastolic pressure (5th phase) equal to or greater than 95 mmHg (127 kPa). Normal blood pressure in adults is equal to or below 140 mmHg (
18.6 kPa
) systolic and 90 mmHg (12.0 kPa) diastolic.
Is blood pressure measured in kPa or mmHg?
Blood pressure, by definition, is how much force the blood exerts on the arteries’ walls. This force is measured in
mmHg (millimeters of mercury) or kPa (kilopascals)
.
Is kPa the same as mmHg?
A pressure measured in millimetres of mercury can be converted to a kilopascals reading using the following conversion factor calculation:
1 kPa = 1000 pascals (Pa) 1 mmHg = 133.322 pascals
(Pa) kPa value x 1000 Pa = mmHg value x 133.322 Pa.
Do doctors use kPa or mmHg?
Doctors feel comfortable with the conventional mm Hg
, but this measurement is as meaningless to individuals with high blood pressure as the kPa is to doctors.
What is ideal mmHg?
A healthy blood pressure reading should be
lower than 120/80 mmHg
. Normal blood pressure is less than 120 mmHg systolic and 80 mmHg diastolic (see blood pressure chart below), and may vary from 90/60 mmHg to 120/80 mmHg in a healthy young woman. A blood pressure of 140/90 mmHg or higher indicates high blood pressure.
Why is blood measured in mmHg?
As mercury is so much denser than water or blood
, even very elevated blood pressures result in it rising no more than about a foot. This quirk of medical history gives us the modern measurement unit for blood pressure: millimetres of mercury (mmHg).
What is kPa a measure of?
Kilopascal (kPa),
one thousand times the unit of pressure and stress in the
metre-kilogram-second system (the International System of Units [SI]). … One pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared.
What is normal blood pressure by age?
| Age SBP DBP | 21-25 120.5 78.5 | 26-30 119.5 76.5 | 31-35 114.5 75.5 | 36-40 120.5 75.5 |

Which arm to measure blood pressure right or left?
(It’s best to take your blood pressure
from your left arm if you are right-handed
. However, you can use the other arm if you have been told to do so by your healthcare provider.) Rest in a chair next to a table for 5 to 10 minutes. (Your left arm should rest comfortably at heart level.)
How do you convert mmHg to kPa?
Multiply the number of millimeters of mercury by 0.13332239
to convert to kilopascals. For example, 25,000 mmHg multiplied by 0.13332239 gives you a conversion of 3333.05975 kPa.
Are Torr and mmHg interchangeable?
One unit of gas pressure is the millimeter of mercury (mmHg).
An equivalent unit to the mmHg is called the torr
, in honor of the inventor of the barometer, Evangelista Torricelli. The pascal (Pa) is the standard unit of pressure.
What does mmHg measure?
The gauge uses a unit of measurement called millimeters of mercury (mmHg) to
measure the pressure in your blood vessels
. If you have high blood pressure, talk to your health care team about steps to take to control your blood pressure to lower your risk for heart disease and stroke.
Why do doctors take blood pressure 3 times?
Each time you measure, take two or three readings to
make sure your results are accurate
. Your doctor might recommend taking your blood pressure at the same times each day. Don’t measure your blood pressure right after you wake up.
Can taking your blood pressure too often make it go up?
Don’t check your blood pressure too often
.
Some people find that they become worried or stressed about small changes in their readings if they take them too often. Worrying can also raise your blood pressure in the short term, making your reading higher than it should be.
How do you convert kPa to mmHg?
- 1 mmHg = 133.322 Pascals (Pa)
- 1 kPa = 1000 Pascals (Pa)
- mmHg value x 133.322 Pa = kPa value x 1000 Pa.
- mmHg value = kPa value x 7.50062.
