How to Use Torr to Psi Converter?

Torr to psi.

The use of this converter is very simple. Just select the conversion direction; torr to psi, or psi to torr. After that, you need to enter that value inside the bracket that you want to convert it to another value. And then click on the “Calculate!” button. And you will see the result in the other bracket.

If you want to make another calculation, you just need to click on the “Reset” button and make the calculation again. So, it will make the calculation much easier.

So, it is very simple to make calculations like this. You just need to make it easier.

How to Make the Torr to Psi Conversion?

Making this conversion is very simple actually. These are the most common pressure values that people are converting to each other.

  • 1 torr equals 0.0193368 psi. So you need to multiply the psi value with the 0.0193368 value to find the torr equivalent of this pressure.
  • The same calculation is valid for the torr to psi calculation. You just need to divide the psi value by 0.0193368 to see the psi value of this pressure.

What is Torr?

Torr is the absolute pressure unit that we use in the SI units. According to the SI units, the 1 torr is equal to the 1mmHg pressure value. This means torr is equal to the 1/760 standard atmospheric pressure.

So, we can think of the torr as the Kelvin of the pressure values. Generally, all the pressure values are calculated according to the torr value. And people are generally searching for the conversion between the different pressure units and the torr.

Actually, the torr comes from “Toricelli” who made the atmospheric pressure calculations with his renowned mercury experiments at the sea level. He measured the atmospheric pressure at 0 degrees Celsius at the sea level as 760 mm/Hg. The atmospheric pressure elevated the mercury 760 mm inside a tube. And we calculate the torr as approximately 1mm/Hg in these conditions.

What is Psi?

Psi is another pressure unit in English units. The meaning of the psi is “pounds per square inch” the total pounds that come to the square per inch. And in engineering calculatioıns, we use them for strength calculations. And it is a very common unit.

The equivalent of the psi in the SI units is the N/mm2 which gives the total force on a millimeter square.

As you see above, these two important pressure units have very different histories.

Where Do We Use Torr?

The most common use of this pressure unit is the atmospheric pressure measurements in scientific applications. So generally we do not see the torr as a common pressure application in daily life. So, people are generally not familiar with this pressure unit.

We generally do not state the total pressure on the solid structures with torr. But sometimes, we need to make conversions between the different pressures.

Where Do We Use Psi?

The use of psi is very common in lots of areas of daily life. For example, while you are inflating your tires, you are generally using this pressure value. And also, while you are doing scientific calculations, the use of the Psi is very common in general.

Because it is one of the most common units in US Units that we are calculating in general.

Other usage areas are very common for the psi. In engineering calculations, we generally define the pressure on the structures as psi. For example, we say “there is a 100.000 psi shear stress coming to this column”. And we know the general maximum strength of these materials that can withstand this pressure or not.

And also, if we need to show the general collections in SI units, the conversion from psi to the N/mm^2 is very easy. So in engineering, this pressure unit is very common. If you are dealing with engineering calculations, especially in structural engineering, you will see that you are using this pressure value in general.

Conclusion on Torr to Psi Conversion

As you see above the cınversion between these two important pressure units is very simple. You just need to calculate it correctly if you want to know the converted value.

How many torrs are in PSI?

If you want to convert the psi value to torr, you need to multiply it by 0.0193368. So it means there are 0.0193368 torrs in psi. The conversion between these two important pressure units is like this.

Is Torr the same as PSI?

They are both pressure units. But they are not the same. Torr is an absolute pressure value that we are calculating. And the PSI is the pressure value that we calculate in English units. They are completely different pressure units.

What is the torr of 1 atm?

In 1 atm there is 760 torr. Because the torr is equal to the 1/760 atmospheric pressure. And we are using this pressure value while we are calculating the absolute atmospheric pressure.

Why there are lots of pressure units?

Because there are different kinds of systems that we are dealing with on a daily basis, engineering basis and scientific basis. To make a sensible comparison between the pressure values, we need to create sensible pressure units to calculate them effectively.
