The Blood Pressure Calculator is a tool used to measure and monitor a person’s blood pressure.
The Blood Pressure Calculator is a tool used to measure and monitor a person’s blood pressure. This calculator uses a simple formula to determine blood pressure, with the person entering their systolic (highest) blood pressure and diastolic (lowest) blood pressure. Blood pressure is an important measurement for assessing cardiovascular health and identifying conditions such as hypertension.
When using the Online Blood Pressure Calculator, you can calculate by entering: Systolic BP and Diastolic BP.

How is Blood Pressure Calculated?
Blood pressure is usually expressed as an upper (systolic) and a lower (diastolic) value. When calculating blood pressure, these two values are taken into account and a formula is usually used. Here is a basic method for calculating blood pressure:
- Systolic Blood Pressure (Upper Pressure): The highest pressure when the heart contracts and pumps blood into the arteries. This value is usually referred to as the upper value of blood pressure.
- Diastolic Blood Pressure (Lower Pressure): When the heart relaxes, this is the lowest level of pressure in the filled arteries. This value is usually referred to as the lower value of blood pressure.
Blood pressure is usually expressed in millimeters of mercury (mmHg). In a typical blood pressure measurement, the systolic pressure measurement lies above the diastolic pressure measurement. For example, a blood pressure expressed as 120/80 mmHg indicates that the systolic pressure is 120 mmHg and the diastolic pressure is 80 mmHg.
When calculating blood pressure, a cuff is usually attached to the arteries in a person’s arm and these values are measured using a blood pressure monitor. However, these values can often be estimated using a blood pressure calculator.
What is Blood Pressure?
Blood pressure is the pressure that blood exerts on blood vessels as it circulates through arteries and other blood vessels. It is measured by the force exerted by the blood on the walls of the arteries as it passes through them, the pressure generated during the contraction of the heart. This pressure is constantly changing as the arteries expand and contract and as blood circulates through the heart. Blood pressure is usually expressed as an upper (systolic) and a lower (diastolic) value.
For example, a blood pressure expressed as “120/80 mmHg” indicates that the systolic pressure is 120 mmHg and the diastolic pressure is 80 mmHg. Blood pressure plays an important role in the regulation of blood circulation in the body and is an important measurement in assessing health status.
How is Blood Pressure Measured?
Blood pressure is usually measured using a blood pressure monitor. Here is how blood pressure is measured in steps:
- Preparation of the Person: For blood pressure measurement, the person should sit in a comfortable position. The arm should be placed comfortably on a table or on the arm of a chair. A comfortable position helps to take an accurate measurement.
- Cuff Placement: The cuff of the blood pressure monitor is wrapped tightly around the person’s upper arm. The cuff should be at elbow level and at heart level. The bottom of the cuff should be approximately 2-3 cm from the arm.
- Using the Meter: Measurement is done using a blood pressure monitor. The device measures blood pressure by inflating the cuff and slowly releasing the air. At this time, the device will display the blood pressure via an audible signal or a digital display.
- Systolic and Diastolic Pressure Readout: The device measures two important blood pressure values during the previous inflation and deflation processes. Systolic pressure indicates the highest pressure in the arteries when the heart contracts, while diastolic pressure indicates the lowest pressure in the arteries when the heart is at rest.
- Recording the Results: The measurement results are noted. Usually, blood pressure values are expressed in millimeters of mercury (mmHg). For example, a measurement expressed as 120/80 mmHg indicates a systolic pressure of 120 mmHg and a diastolic pressure of 80 mmHg.
Blood pressure measurement is an important routine medical procedure for assessing health status and monitoring conditions such as hypertension.
Factors Affecting Blood Pressure
There are a number of factors that affect blood pressure. Here are some of them:
Age: With age, blood vessels can harden and lose their elasticity, which can increase blood pressure.
Gender: Generally, men have slightly higher blood pressure than women. However, women’s blood pressure may increase after menopause.
Familial Features: People with a family history of hypertension are more likely to have high blood pressure.
Weight and Body Mass Index (BMI): Higher body mass index (BMI) and obesity are often associated with higher blood pressure.
Diet: Consumption of high-salt, fatty and processed foods can increase blood pressure. Inadequate intake of potassium, calcium and magnesium can also affect blood pressure.
Physical Activity Level: Regular exercise can lower blood pressure, while being physically inactive can increase blood pressure.
Stress: Chronic stress can increase blood pressure.
Alcohol and Smoking: Excessive alcohol consumption and smoking can increase blood pressure. Blood Alcohol Content (BAC) Calculator
Chronic Diseases: Chronic health problems such as diabetes, kidney disease, thyroid problems and sleep apnea can affect blood pressure.
All of these factors combine to affect an individual’s blood pressure. It is important to adopt a balanced lifestyle and have regular medical check-ups to keep blood pressure at healthy levels.
Symptoms and Risks of High and Low Blood Pressure
The symptoms of high blood pressure (hypertension) can often be subtle and most people experience no symptoms at all. However, long-term high blood pressure can cause serious health problems.
The risks of high blood pressure can include:
- Heart Disease and Stroke: High blood pressure can increase the risk of heart attack, heart failure and stroke. Consistently high blood pressure can lead to damage to the arteries and heart muscle and lead to blockages of blood vessels.
- Kidney Damage: High blood pressure can damage your kidneys and increase the risk of kidney failure.
- Eye Problems: High blood pressure can damage blood vessels in the retina and lead to eye problems or even loss of vision.
- Blood Vessel Problems: High blood pressure can damage arteries anywhere in your body and lead to problems such as hardening of the arteries (atherosclerosis).
Symptoms of low blood pressure (hypotension) may include:
- Dizziness and Headache: Low blood pressure can cause dizziness and headaches due to insufficient blood flow.
- Dizziness and Fainting: Low blood pressure can lead to fainting or dizziness when the brain does not receive enough oxygen.
- Weakness and Fatigue: When not enough oxygen and nutrients are transported to body tissues, you may feel weak and tired.
- Shortness of breath Low blood pressure can cause shortness of breath when not enough blood is pumped to the heart and lungs.
The symptoms and risks of high and low blood pressure can vary from person to person. Therefore, it is important to consult a healthcare professional if you have any symptoms or concerns.
