pascal to pound/sq inch Converter
Convert Pa to psi and back with a live reference table.
1 Pa = 0.000145038 psi\n5 Pa = 0.000725189 psi\n10 Pa = 0.00145038 psi\n25 Pa = 0.00362594 psi\n50 Pa = 0.00725189 psi\n100 Pa = 0.0145038 psi
Why this conversion matters
Pascals are SI pressure units, while psi remains common for tires, tanks, tools, and US equipment specs. 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, 101325 Pa converts to 14.6959 psi. Switching the direction shows the inverse relationship, so 14.6959 psi converts back to 101325 Pa with the same factor.
Formula and privacy note
The calculation uses 1 Pa = 0.000145038 psi. 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 Pa = 0.000145038 psi, 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 Pa to psi or psi to Pa 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.
