## What is Pressure?

In the physical sciences, Pressure is the force per unit area’ applied perpendicularly to an object. Or the term "pressure" can also refer to the amount of force exerted by a confined fluid.

### What are Imperial and Metric Pressure Units?

• Metric Units: Firstly, let's look at the SI system, which is the International System of Units, derived from the metric system. The SI system is the world's most widely used measurement system. Despite the fact that the SI system is used in the majority of countries, there are also many other pressure units in use.
• Imperial Units: The engineering units used in countries using the Imperial system (such as the USA and UK) are different from the SI units. As a result, these nations also have a different set of pressure units. Pounds per square inch (Psi) is the most commonly used pressure unit in the United States.

A common unit for process industries is inches of water (inH2O), which is derived from the measurement of level differences and the historical measurements of pressure differences with water in a column.

### What are the Different Units of Pressure?

In different parts of the world, there are different pressure units that can be confusing and may lead to misunderstandings. There are some standard SI units of pressure like Atmosphere standard & Atmosphere technical, Bar, Mercury (in Hg), Mercury (mm Hg), PSI, Pascal, Torr, inH2O.

### Stepwise Conversion of thePressure UnitsusingManual Method

1. Find out the unit of pressure that you want to convert into.
2. Then find the conversion factor of the units from the table given above.
3. By knowing the conversion factor, converting between units is as easy as multiplying.
4. Now, according to the conversion table, 1st we will convert the given unit into atmospheric standard pressure by dividing the units’ value conversion factor & then multiplying the conversion factor of the resulting unit.
5. Now, after performing calculations, the output value is the pressure converted into another unit.

### Solved Example of PressureConversionwith detailed Steps

Example:

Convert 20 PSI of pressure into inH2O.

Solution:

Given that 20 PSI Units of Pressure

To perform the required conversion from PSI to inH2O, let's determine the conversion factor using theconversion table.

Thus, first, we will convert psi into atmospheric standard pressure by dividing psi value conversion factor 14.6959 & then multiplying the conversion factor of inH2O which is 406.7937.

Now, the calculation will be like this,

20 PSI = (20/14.6959) × 406.7937

= 554.152 inH2O

### FAQs On Pressure Unit Online Converter with Steps

1. Which formula is generally used in conversion for pressure?

The formula to calculate the pressure is P = F/A. The SI unit of pressure is Pascal (Pa).

2. How do you convert pressure to SI units?

The unit of pressure in the SI system is the pascal (Pa). The conversion between 3 different units of Pressure atm, Pa, and the torr is as follows: 1 atm = 101325 Pa = 760 torr.

3. How do you do pressure conversion charts?

The simple method to use pressure conversion charts is to first find out the unit of pressure that we wish to convert from the left-hand column and then multiply it with the value present in the corresponding pressure unit column.

4. What is the difference between Torr and mmHg?

The major difference between torr and mmHg is that the value of one torr can be easily obtained by the division of 101325 and 760, whereas the value of one mmHg is given exactly as 133.3224.
