About converting Bars to Pascals
Bars (bar) and Pascals (Pa) are both units of pressure, so converting between them is a single multiplication: multiply your Bars figure by 100,000. Ten Bars comes to 1,000,000 Pascals, and a hundred works out at 10,000,000 Pascals.
Rule of thumb: going from Bars to Pascals multiplies, so the figure always grows — one Bar is already 100,000 Pascals. If your answer came out smaller, you have the conversion the wrong way round.
What is a Bar?
The bar is not an SI unit, but it is accepted for use alongside them, and it earns that place by sheer convenience: it was chosen to sit close to average atmospheric pressure, so "one bar" reads as roughly what the air is doing right now. It dominates European industry — compressed air, hydraulics, scuba cylinders, espresso machines and tyre pressures are all quoted in bar. Its subdivision the millibar had a long career in weather forecasting before being quietly replaced by the hectopascal, which is exactly the same size, so nothing on the old charts had to change.
What is a Pascal?
The pascal is the SI unit of pressure: one newton spread over one square metre. It is named after Blaise Pascal, who established that air pressure falls with altitude by having a barometer carried up a mountain. The awkward thing about the unit is its scale — a single pascal is a very small pressure indeed, so honest real-world figures come out enormous, atmospheric pressure alone being about 101,325 of them. That is why hardly anyone works in bare pascals: engineers reach for kilopascals, meteorologists for hectopascals, and industry for the bar.
To put both in perspective: a scuba tank is filled to about 200 bar, while sea-level air pressure is about 101,325 pascals.

Frequently asked questions
How many Pascals are in one Bar?
There are 100,000 Pascals in one Bar.
How do I convert Bars to Pascals?
Multiply the number of Bars by 100,000. For example, 10 Bars = 1,000,000 Pascals.
What is 100 Bars in Pascals?
100 Bars is equal to 10,000,000 Pascals.
How do I convert Pascals to Bars?
Multiply the Pascals value by 0.00001 (or divide by 100,000).
Is this Bars to Pascals conversion exact?
Yes, exactly. Both units are fixed against the same base by definition, and 1 Bar = 100,000 Pascals is the complete value — nothing is rounded away.
