Pound per square inch vs Kilogram-force per square centimetre: which is bigger?
A kilogram-force per square centimetre is the larger unit: one kilogram-force per square centimetre equals 14.22334 pound per square inchs. Put another way, you need 14.22334 pound per square inchs to make a single kilogram-force per square centimetre.
What is a Pound per square inch? History, origin and usage
Pounds per square inch grew directly out of the steam age: boiler safety valves were rated by how many pounds of weight it took to hold them shut over a known area, and the unit survived into every later technology that Britain and the United States industrialised. It never went through a formal international definition of its own — instead it became exact in 1959, when the yard-and-pound agreement fixed the pound and the inch exactly, and again through the fixing of standard gravity, which pins down what a "pound of force" means.
Psi is the standard pressure unit in the United States and remains widely understood in Britain, India and elsewhere: tyre pressures, air compressors, pressure washers, water mains, hydraulic lines and scuba tanks. Car tyres are commonly inflated to around 30 to 35 psi.
Psi is exactly defined but its value in pascals is a decimal that repeats forever, so any written figure is necessarily rounded somewhere. Gauges usually read gauge pressure — the amount above surrounding air — which is why a flat tyre reads zero rather than about 14.7.
What is a Kilogram-force per square centimetre? History, origin and usage
The kilogram-force per square centimetre, also called the technical atmosphere, belongs to the old metric engineering system that used the kilogram-force rather than the newton as its unit of force. It dominated European, Soviet and Indian engineering practice for most of the twentieth century, and although SI formally replaced it, the gauges and nameplates outlasted the standard.
It still appears on pressure gauges, compressors, boilers, tyre charts and machinery plates across India, Russia, Japan and parts of Europe — often abbreviated to just "kg/cm²", which is technically a mass over an area rather than a pressure but is universally understood to mean this unit.
It is exactly 98,066.5 pascals, which is within about 2% of one bar and within about 3% of one atmosphere. That closeness is why old gauges marked in kg/cm² can be read approximately as bar without anyone getting into trouble — and why precise work must not do so.

Tips for converting Pound per square inch to Kilogram-force per square centimetre
- To go from pound per square inch to kilogram-force per square centimetre, multiply by 0.07030696; to go back, divide by 0.07030696 (or multiply by 14.22334).
- For a quick mental estimate, remember that 1 pound per square inch ≈ 0.07030696 kilogram-force per square centimetre, so 10 pound per square inch ≈ 0.7030696 kilogram-force per square centimetre.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Pound per square inch to Kilogram-force per square centimetre converter
Type a number into the Pound per square inch field and the equivalent in Kilogram-force per square centimetre appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Kilogram-force per square centimetre field to convert the other way (kilogram-force per square centimetre to pound per square inch). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 psi = 0.07030696 kgf/cm²), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for pound per square inch-to-kilogram-force per square centimetre conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- NIST Special Publication 811 — Guide for the Use of the SI — publishes the exact metric equivalents of the customary pressure units. A psi is one pound of force over one square inch, and the 1959 international yard-and-pound agreement fixes the pound at exactly 0.453 592 37 kilogram and the inch at exactly 0.0254 metre, while standard gravity is fixed at exactly 9.806 65 m/s² — so psi, inches of mercury and inches of water are defined exactly rather than measured.
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
Pressure factors here come from fixed definitions, anchored to the pascal: a bar is exactly 100,000 Pa, one atmosphere is exactly 101,325 Pa, a torr is exactly a 760th of an atmosphere, and psi is built from the exact pound and the exact inch. Two of them — psi and the torr — work out to decimals that repeat forever, so where a number is shown rounded it is marked, not quietly trimmed.
