Pressure Conversion Calculator (PSI ↔ kPa)

Convert pressure readings between PSI and kilopascals for pumps, compressors, and water systems.

Computed in your browser — nothing you enter is uploaded. Figures are presented for United States against IRC 2024, and every formula is cited under regulatory standards below.

Converted pressure

206.84 kPa

High confidence

With the figures above, the converted pressure comes to 207 kPa. Note that pressure sits at the low end of the range this calculator was checked against, so treat the output as indicative rather than settled. This is calculated for United States and cites IRC 2024. Building in another market? Change the selector above so the units and code reference follow.

Add the equipment this sizes

This result is a specification — 206.843 kPa — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Frequently asked questions

Where does pressure conversion come up in home projects?
Common cases: checking a well pump or pressure tank's cut-in/cut-out spec against your gauge, comparing a compressor's rated output, or reading a metric-labeled appliance spec against a US pressure gauge.
What's a typical residential water pressure range?
Most homes run 40-60 PSI (about 275-415 kPa) at the fixtures — below 40 PSI can feel weak, and above 80 PSI (550 kPa) risks damaging fixtures and appliances over time, often requiring a pressure-reducing valve.
Is bar the same as kPa?
No, though they're related — 1 bar = 100 kPa exactly, and 1 bar ≈ 14.5 PSI. If your spec is in bar, multiply by 100 to get kPa, then use this calculator.
