bar to kilopascal Converter
Convert bar to kPa and back with a live reference table.
1 bar = 100 kPa\n5 bar = 500 kPa\n10 bar = 1000 kPa\n25 bar = 2500 kPa\n50 bar = 5000 kPa\n100 bar = 10000 kPa
Why this conversion matters
Bar and kilopascals both appear on pressure gauges, and one bar is exactly 100 kilopascals. The widget keeps the direction explicit so you can enter either side of the pair without doing the reciprocal by hand. It is built for quick checks where a calculator, specification sheet, recipe, map, or lab note uses the other unit.
For the default example, 2.5 bar converts to 250 kPa. Switching the direction shows the inverse relationship, so 250 kPa converts back to 2.5 bar with the same factor.
Formula and privacy note
The calculation uses 1 bar = 100 kPa. Forward conversion multiplies by that factor, and reverse conversion divides by it. Results are rounded to six significant figures for readable estimates, so very small scientific units and large planning units stay scannable. Check the unit labels before copying a result, especially when similar abbreviations appear in the same project. The reference table is generated from the same constant, and everything runs locally in your browser.
Frequently Asked Questions
What factor does this converter use?
It uses the standard factor 1 bar = 100 kPa, then applies the reciprocal for the reverse direction.
Why are results rounded?
The main result is rounded to six significant figures so very large and very small values stay readable while preserving the useful precision for quick checks.
Can I convert both directions?
Yes. Choose bar to kPa or kPa to bar from the direction menu and the output updates immediately.
Is this converter private?
Yes. The conversion runs entirely in your browser, and the value you enter is not uploaded or stored.
