Bar to PSI Conversion Formula

To convert bar to PSI, multiply the bar value by 14.503768. One bar is defined as exactly 1,00,000 pascals (one lakh), and one PSI equals 6,894.76 pascals.

Bar and PSI Explained

Bar (bar)

The bar is a metric pressure unit defined as exactly 1,00,000 pascals (one lakh) — deliberately close to the 101,325-pascal standard atmosphere at sea level. That near-atmosphere size makes it practical for everyday ratings: a hatchback tyre holds about 2.2 bar, an espresso pump delivers 9 bar, and a full scuba cylinder stores 200 bar. Because its pascal definition is a round power of ten, the bar converts cleanly inside the metric system.

Where it is used: Bar appears on imported car and motorcycle door stickers, diving cylinders, boiler and machinery nameplates; dive operators in the Andamans and at Netrani Island, like the diving industry worldwide, rate cylinders in bar.

Origin: British meteorologist William Napier Shaw introduced the bar in 1909, naming it after the Greek baros, meaning weight, as a convenient near-atmosphere unit.

PSI (psi)

PSI (pound-force per square inch) is the imperial pressure unit: one pound of force applied over one square inch of area. In SI terms it equals 6,894.76 pascals. As a finely scaled unit, PSI numbers run large — a 2.2 bar door sticker becomes 31.9 PSI, and a 200 bar scuba cylinder becomes 2,900.8 PSI. Gauge readings marked PSIG measure pressure above the surrounding atmosphere, while PSIA readings include it.

Where it is used: PSI is what most Indians encounter daily: tyre inflators at Indian Oil, HP and Bharat Petroleum petrol pumps, workshop compressors, CNG filling stations, and authorised service-centre manuals all quote it, as do pressure-washer ratings.

Origin: The unit grew out of 19th-century British engineering practice, pairing the imperial pound-force with the square inch, and it remains standard in US customary use today — and on most gauges sold in India.

When You Need Bar to PSI Conversions

Imported Car Tyre Stickers

Your imported Volkswagen or BMW lists 2.4 bar on the door jamb, but the air gauge at the petrol pump on the Mumbai–Pune Expressway reads PSI — enter 2.4, inflate to 34.8 PSI, and do the needful for the remaining three tyres.

Scuba Fills at Andaman Dive Centres

A dive centre on Havelock Island fills cylinders by bar while your gauge dial is in PSI, so a 207 bar fill becomes 3,002.3 PSI before you splash at Elephant Beach.

Hydraulic Unit Nameplates

A German hydraulic power pack rated 250 bar must be verified against a PSI gauge at your Pune plant — 250 bar is 3,625.9 PSI on the dial.

Espresso Machine Service

Bench-testing an imported espresso machine at a Bangalore café, you hold the pump at 9 bar and need to log 130.5 PSI on the technician's test gauge.

How to Use

  1. 1

    Enter Bar Value

    Type the bar reading from your gauge or door sticker — common entries include hatchback tyre pressures (2.0-2.5 bar), imported espresso pumps (9 bar), or scuba cylinders in the Andamans (200-232 bar)

  2. 2

    View PSI Result

    The equivalent PSI value appears instantly. For example, 2.2 bar on a Maruti Swift door sticker converts to about 31.9 PSI

  3. 3

    Copy or Swap

    Copy the result or click Swap to convert PSI back to bar

  4. 4

    Check Against Petrol Pump Gauges

    Compare with the reading at your neighbourhood Indian Oil or HP petrol pump. Most hatchbacks and sedans run 30-36 PSI (2.1-2.5 bar) cold, so a 2.2 bar tyre sits comfortably at 31.9 PSI. In 45°C Delhi summer heat, always check pressures before the tyres warm up

Frequently Asked Questions

How many PSI is 1 bar?
1 bar equals 14.503768 PSI. So the 2.2 bar printed on a Maruti or Hyundai door sticker equals about 31.9 PSI, and a 200 bar scuba fill at a Havelock Island dive centre equals about 2,900.8 PSI.
What is 2.3 bar in PSI?
2.3 bar × 14.503768 = 33.4 PSI. This is a typical cold tyre pressure for cars like the Maruti Swift, Hyundai i20 or Tata Nexon, especially with the rear seats loaded — matching figures quoted in most owner's manuals.
What is the difference between bar and PSI?
Bar is the metric pressure unit used on imported vehicles, diving gear and industrial equipment, while PSI (pounds per square inch) is what most Indian tyre inflators and workshop gauges display. 1 bar ≈ 14.5 PSI. A door sticker reading 2.2 bar means the same as 31.9 PSI on the air line at your local petrol pump.
How do I convert scuba tank pressure from bar to PSI?
Multiply bar by 14.503768. A standard 200 bar aluminium tank equals about 2,900.8 PSI. A 232 bar steel cylinder equals about 3,364.9 PSI, and a high-pressure 300 bar fill equals about 4,351.1 PSI — ratings you will see at Andaman and Netrani Island dive centres.
Is 1 bar the same as 1 kg/cm2?
Nearly, but not exactly. The older metric unit kilogram-force per square centimetre (kg/cm²) equals about 0.981 bar, so the two differ by roughly 2 percent. Many older Indian gauges and BIS specifications still show kg/cm², so it is worth knowing the difference — modern specifications use bar or pascals to avoid this ambiguity.
How many PSI is 10 bar?
10 bar equals 145.0 PSI. That is a common rating for workshop air compressors and paint-spraying equipment in auto garages — about the same as a 145 PSI compressor setting.
Is bar used in India?
Yes, quite often. Imported car and bike door stickers, diving cylinders, imported machinery, and espresso machines all quote bar, while most petrol-pump tyre inflators read in PSI and older gauges in kg/cm². That mix of units is exactly when a bar to PSI converter becomes handy.
How many PSI is 300 bar?
300 bar equals 4,351.1 PSI. This is a high-pressure scuba rating used at technical diving centres; cylinders marked 300 bar need fill stations and regulators rated for 4,400 PSI service or higher.

About Bar to PSI Converter

Our free online bar to PSI converter provides instant, accurate pressure conversions. Whether you are checking the door sticker on an imported Volkswagen in Mumbai, topping up your bike's tyres before a monsoon ride to Lonavala, filling a scuba cylinder at a Havelock Island dive centre, or verifying a JCB hydraulic system on site, this tool gives you precise results. Bar appears on imported equipment and diving gear, while PSI (pounds per square inch) is what most Indian petrol-pump inflators and workshop gauges display. Our converter uses the exact conversion factor where 1 bar equals 14.503768 PSI.

Expert Tips for Bar to PSI Conversion

1

For quick tyre checks: 2.0 bar ≈ 29.0 PSI, 2.2 bar ≈ 31.9 PSI, 2.3 bar ≈ 33.4 PSI, 2.5 bar ≈ 36.3 PSI. Memorise these four and you can handle most door stickers — just check pressures cold, before 45°C summer heat adds extra PSI

2

Espresso machines brew at 9 bar — that is 130.5 PSI of pump pressure. If your technician's gauge reads in PSI, look for roughly 130 during extraction, a common check at speciality coffee roasters in Bangalore and Pune

3

Scuba cylinders come in 200 bar (2,900.8 PSI), 232 bar (3,364.9 PSI), and 300 bar (4,351.1 PSI) ratings. Match your regulator and the fill station at Andaman or Netrani dive centres to the cylinder stamp

4

Your kitchen pressure cooker — Prestige, Hawkins or Butterfly — whistles at roughly 0.7-1.0 bar above atmospheric pressure, which is only 10-14.5 PSI. The same conversion helps when checking geyser and solar water heater pressure ratings

5

For mental math, multiply bar by 14.5 instead of 14.503768. The error is under 0.03 percent, fine for a quick check at the petrol pump, but use the exact factor for service records and documentation
