Pascal Conversion Calculator

The pascal conversion calculator works out pressure in pounds per square inch, pressure in atmospheres and pressure in pascals from pressure in bars. Enter what you have and the relationship is applied straight away, so you get the answer without working through the algebra yourself.

What Is the Pascal Conversion Calculator?

The pascal conversion calculator converts pressure in bars between the units you need, so you do not have to hunt for a factor and work it out longhand.

Conversion factors are where unit mistakes happen, and a mistake here tends to propagate silently into everything calculated from it afterwards.

How the Pascal Conversion Conversion Works

Each conversion uses the exact factor defined for the unit, so the answer is right to the precision you would normally quote.

Convert at one end rather than at several. Converting to a common unit first and then back again introduces rounding that you then have to carry through the rest of the calculation.

Getting the Units Right

Check that the unit you are converting from is the unit you actually measured in. Similar-looking units, particularly gallons and litres or ounces and grams, are the usual source of a factor-of-ten error.

Write down both the value and its unit. A number without a unit is not a measurement, it is a guess.

A Worked Example

Working through an example, with pressure in bars set to 10, the calculator returns pressure in pounds per square inch of 10, and pressure in atmospheres of 10, and pressure in pascals of 10. Substitute your own figures and the same steps produce the same kind of answer.

Frequently Asked Questions

What do I need to work out pressure in pounds per square inch?

Enter pressure in bars. The calculator then works through the relationship and reports pressure in pounds per square inch, pressure in atmospheres and pressure in pascals.

What does the pascal conversion actually calculate?

It takes pressure in bars and converts them into pressure in pounds per square inch, pressure in atmospheres and pressure in pascals using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.

How should I enter pressure in bars?

Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.

Why does a small change in one value move the answer so much?

That happens when an output depends on a ratio, because dividing by a small number magnifies any change in it. Check the units first, then check whether the value you entered is in the range the relationship was designed for.

Is the answer exact?

It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
