What does Pound per Square Inch mean?
PSI stands for pounds per square inch. It is used as a unit of pressure.
PSI can be defined as the amount of pressure or stress of a pound of force per square inch of area. The symbol of psi is lb/in² or lbf/in².
PSI is commonly used in many pressure measuring applications like tire pressure, soil bearing capacity, wastewater management, fuel distribution & storage.
Following are the major conversion for the PSI unit.
- 1 PSI= 6894.76 Pascals (SI unit conversion)
- 1 PSI= 0.0689476 Bar
- 1 PSI= 0.068046 atmospheres
- 1 PSI= 51.7149 Torr
- 1 PSI= 2.03602 inHg
- 1 PSI= 27.7076 inches of the water column

What does Millimetre of Mercury mean?
Millimeters of mercury (mmHg) is a unit of pressure measurement that is commonly used in medicine and meteorology. It is also known as millimetres of water column, which is abbreviated as mmWC.
The mmHg unit is defined as the amount of pressure exerted by a column of mercury that is 1 millimeter high and has a density of 13.5951 g/cm³, which is the density of mercury at 0°C. This unit of pressure is used extensively in medicine, especially in the measurement of blood pressure.
To understand the concept of mmHg, it is important to first understand what pressure is. Pressure is the amount of force exerted per unit area. In the case of mmHg, it is the amount of force exerted by a column of mercury that is 1 millimeter high.
The normal range for blood pressure in adults is around 120/80 mmHg. This means that the pressure exerted by the blood in the arteries when the heart beats (systolic pressure) is around 120 mmHg, and the pressure exerted when the heart is at rest (diastolic pressure) is around 80 mmHg.
In addition to medicine, mmHg is also commonly used in meteorology to measure barometric pressure, which is the pressure exerted by the Earth's atmosphere. Barometric pressure is an important factor in weather forecasting as it helps predict weather patterns and changes.
Another unit of pressure measurement that is commonly used is the kilopascal (kPa). To convert mmHg to kPa, the following equation is used: 1 mmHg = 0.133 kPa.
In summary, millimeters of mercury (mmHg) is a unit of pressure measurement that is commonly used in medicine and meteorology. It is defined as the amount of pressure exerted by a column of mercury that is 1 millimeter high and has a density of 13.5951 g/cm³. This unit is used extensively in the measurement of blood pressure and barometric pressure.
What does Pressure mean?
Pressure is a kind of force. In the language of physics, a force is an object that changes or tries to change its state by acting on it or that changes or tries to change its motion by acting on a moving object.
For example, if someone pushes against a wall, the force is applied whether it changes its position or not. This effort is called force. On the other hand, the force exerted on a single area is called pressure.
This means that if we apply a force in a single case, it will be a force.
Pressure = (force ÷ area)
As an example, it is easy to take a photo with a pin because the area is less. Again, more pressure is required in the area.
The Unit of Pressure
Pressure scalar quantity, because it has value but has no direction. The SI unit of pressure is Pascal, which is equal to Newton per square meter (N/m²). Since an object or group of objects under pressure can act on its surroundings, the pressure is also measured as static energy in a single volume. It is related to the density of energy and can be expressed in joules unit per cubic meter (joules/m³, which is equal to Pascal). To make this concept precise, we use the idea of pressure. The pressure is defined to be the amount of force exerted per area.
Thanks for reading this article! Hopefully, it helps you understand what pressure is and how we measure the pressure of an object.
