What is Pressure?
- Pressure is Force Exerted Per Unit Area
- P = F / A where F is the force and A is unit area
- The SI unit of Pressure is Pascal (Pa)
- 1 Pascal is defined as the force of 1 Newton applied on an area of 1 square m, 1 Pa = 1 N/m2
What are the different Pressure Units?
Torr (mmHg)
- mmHg stands for Millimeter of Mercury (Hg).
- It is also known as 'Torr' named after physicist Toricelli who invented the barometer
- It is the pressure exerted by mercury. occupying 1 mm height in a column.
- Higher the density of the substance, the higher will be the pressure and vice versa.
- The atmospheric pressure is equal to 760 mm Hg.
- mmHg is still most commonly used in medical / clinical measurements like blood pressure (120mmHg / 80 mm Hg) and other pressures within the human body
mmH2O
- This is pressure exerted by a column of water of height 1 mm.
- The atmospheric pressure 1 atm is equal to 10,332 mm of water (mmH20)
- The mmH2O is used to measure very low pressures such as lung pressure or cranial pressure, air condition pressure
Bar
- The bar is a unit of pressure that is almost equal to atmospheric pressure.(1 bar = 0.98 atm)
- The bar is 100 times of Kilopascal.
- It is a metric unit of measurement and used to measure very high pressure.
- The bar is widely used in mechanical areas, industrial applications, construction systems wherever high pressure is involved.
Pounds Per Square Inch (psi)
- Pounds per Square inch is the unit of pressure in the Imperial system of measurement (US)
- It is defined as the force measured in lbs acting on a surface area of 1 square inch. The symbol used is psi.
- Standard atmospheric pressure 'at' is equal to 14.97 psi
- The psi is widely used as the unit of pressure in domestic and commercial applications alongside pascal
- Bite force in animals (pressure exerted by jaw muscles while biting) is expressed in psi .
- For example, crocodile's psi is between 3500 to 5000 psi, hyena's is around 1000 psi, human beings is around 150-200 psi
Atmosphere (Atm)
- It is the air / atmospheric pressure at sea level.
- One Atmospheric pressure is equal to 760mmHg or around 101 KiloPascals.or 14.7 psi
- The atmospheric pressure at sea level is used as a reference point
- It is mainly used for weather forecasting.
Pascal (Pa) and KiloPascal (KPa)
- It is the SI unit of Pressure named after scientist 'Blaire Pascal'
- The symbol used for Pascal is Pa
- It is defined as the force exerted on a unit area
- Pa = N/m2 = kg/m s2
- A kilopascal (KPa) is a larger unit and equal to 1000 Pascals
- Both Pascal and Kilopascal are the standard units of pressure measurement and widely used in all spheres - research, engineering, weather, medical, mechanical systems, aircrafts
- Atmospheric pressure at sea level is 101 KPascals. Tire pressure is around 200-220 kilo pascals

Frequently Asked Questions on Pressure conversion
Which is the largest unit of Pressure?
The Atmosphere (atm) is the largest unit of pressure.
It is 1.01 times of bar and roughly 100,000 times of Pascal
Which is bigger Bar or KiloPascal or Megapascal?
MegaPascal (mPa) is the largest.
Bar is bigger than Kilopascal and smaller than Mega pascal
A bar is 100 times of KiloPascal and 0.1 f Megapascal
Which is the smallest unit of Pressure?
Pascal is the smallest unit of pressure. It is equal to the force of 1 newton acting on an area of 1 cubic meter (1 N / m2)
What is Pascal's law?
Pascal's law is related to transmission of pressure.
When pressure is applied to any part of a fluid (when there is change of pressure), it is equally transmitted to all parts of the fluid and container
This principle forms the basis of hydraulic systems such as brakes, lifts, jacks
