Convert Pa to bar
How the conversion works
By definition, 1 bar = 100 000 Pa. Therefore:
bar = Pa ÷ 100 000
1 Pa = 1×10-5 bar
This tool applies that exact factor and formats the output to your chosen precision.
Result
Enter a numeric value in pascals and click Calculate to see the conversion.
Tips
- Use scientific notation for very large or small pressures (e.g.,
3.7e7
). - Negative values are allowed if your data represents relative pressure.
- Adjust decimal places to balance readability and precision.
Frequently Asked Questions
1) What is the exact conversion from pascals to bar?
One bar equals 100,000 pascals. To convert, divide the value in pascals by 100,000 to obtain bar.
2) Does this tool support scientific notation?
Yes. Inputs like 1.01325e5
are accepted and interpreted correctly.
3) How many decimal places should I choose?
It depends on your use case. Engineering summaries may use 2–4 decimals, while lab analyses may require more precision.
4) Can I enter negative pressures?
Yes. Negative values can represent gauge pressures or relative offsets below a chosen reference.
5) What is the difference between absolute and gauge pressure?
Absolute pressure is measured relative to a vacuum; gauge pressure is measured relative to ambient atmospheric pressure. Convert units the same way, but interpret values accordingly.
6) Will rounding affect engineering decisions?
Rounding affects display only. Internally the exact factor is used; choose sufficient decimal places to avoid misleading rounding.
7) Can I use this for batch conversions?
This page focuses on single values. For batch needs, integrate this factor (1e-5
) into your spreadsheet or script.
