What is the PSI to kPa conversion formula?

To convert PSI to kPa: multiply PSI by 6.895. To convert kPa to PSI: divide kPa by 6.895. For example, 35 PSI × 6.895 = 241.3 kPa, and 240 kPa ÷ 6.895 = 34.8 PSI. Our calculator does this instantly for you!

Why do I need to convert tire pressure units?

Your car's door sticker may show tire pressure in kPa (like 240 kPa), but your tire gauge reads in PSI. Converting ensures you inflate to the exact manufacturer specification for optimal safety, fuel economy, and tire life.

What tire pressure is 35 PSI in KPA?

35 PSI equals 241.3 kPa. This is a common tire/tyre pressure for passenger cars. Many European and Asian vehicles specify this pressure in kPa on the door placard.

Is 2.2 bar the same as PSI or KPA?

2.2 bar equals 32 PSI or 220 kPa. Bar is another pressure unit (1 bar = 14.5 PSI = 100 kPa). Use our converter for instant conversions between all pressure units!

What's better for tire pressure: PSI or KPA?

Neither is 'better' - they're just different measurement units. PSI is common in the US, while kPa is used internationally. Always use the unit specified by your vehicle manufacturer for accuracy, whether it's tire or tyre pressure.

How do I read kPa pressure on my car's door sticker?

Look for numbers like '240 kPa' or '2.4 bar' on your driver's door jamb. This is your recommended cold tire pressure. If your gauge reads PSI, convert using our tool: 240 kPa = 34.8 PSI.

How do I convert tyre pressure from PSI to kPa?

Tyre pressure conversion from PSI to kPa is easy: multiply the PSI value by 6.895. For example, 35 PSI × 6.895 = 241.3 kPa. Our tyre pressure converter does this calculation instantly for accurate results every time!

What is 32 PSI in kPa?

32 PSI equals 220.6 kPa (32 × 6.895). This is a common tyre pressure for compact cars and small SUVs. In bar, 32 PSI = 2.21 bar. Always verify the correct pressure for your specific vehicle on the doorjamb sticker.

How does bar relate to PSI and kPa for tyre pressure?

1 bar = 100 kPa = 14.504 PSI. So 2.4 bar = 240 kPa = 34.8 PSI, and 2.5 bar = 250 kPa = 36.3 PSI. Bar is commonly used on European tyre pressure gauges. Our conversion chart above shows the full range from 1.9 bar (190 kPa) to 3.1 bar (310 kPa) in PSI.

Do motorcycles, bicycles, and golf carts use the same PSI-to-kPa conversion as cars?

Yes — the conversion formula is identical for every vehicle type (PSI × 6.895 = kPa); only the target pressure range changes. Motorcycles typically run 193–290 kPa (28–42 PSI), road bicycles run much higher at 552–896 kPa (80–130 PSI), and golf carts run much lower at 124–152 kPa (18–22 PSI). See the vehicle reference table above for the full range by vehicle type.

QUICK EXAMPLE

Your UK vehicle's doorjamb shows 240 kPa — what is that in PSI? Divide by 6.895: 34.8 PSI. Or your US gauge reads 35 PSI — that's 241.3 kPa or 2.41 bar. The three formulas are always: kPa ÷ 6.895 = PSI, PSI × 6.895 = kPa, and bar × 100 = kPa. This converter handles all three units instantly, in both directions.

kPa / bar / PSI Conversion Table

Common tyre pressure values from 190 kPa to 310 kPa. Door stickers in the UK, Australia, and Europe typically use kPa or bar — use this chart to find the PSI equivalent instantly.

kPa	bar	PSI	Common use
190	1.9	27.6
200	2.0	29.0
210	2.1	30.5
220	2.2	31.9	Low end — small cars, summer tyres
230	2.3	33.4	Front tyres, many compact cars
240	2.4	34.8	★ Most common passenger car value
250	2.5	36.3	★ Common — midsize cars & SUVs
260	2.6	37.7	SUVs, loaded rear axle
270	2.7	39.2
280	2.8	40.6	Higher-load vehicles, some vans
290	2.9	42.1
300	3.0	43.5	Light trucks, LT tyres (front)
310	3.1	45.0

1 kPa = 0.1450 PSI · 1 PSI = 6.895 kPa · 1 bar = 100 kPa = 14.504 PSI

About This Calculator

This PSI to kPa converter makes pressure unit conversion instant — enter any value in PSI, kPa, or bar and get the equivalent in the other units. Essential for UK, Australian, and European drivers where vehicles specify pressure in kPa (like 240 kPa) but gauges often read in PSI. Correct inflation is vital for tyre life, fuel economy, and safe handling.

PSI (Pounds per Square Inch) is commonly used in the United States, while kPa (Kilopascals) is the SI metric unit used internationally by vehicle manufacturers. Bar (1 bar = 100 kPa = 14.504 PSI) is widely used on European gauges.

Tyre / Tire Pressure Reference by Vehicle Type

Typical recommended tyre/tire pressures by vehicle category. These are general ranges — always check your specific vehicle's doorjamb sticker or owner's manual for the correct cold inflation pressure.

Vehicle Type	Front (PSI)	Rear (PSI)	Front (kPa)	Rear (kPa)	Notes
Compact car (e.g., VW Golf, Honda Civic)	30–35	30–35	207–241	207–241	Check doorjamb sticker
Midsize sedan (Camry, Accord)	32–35	32–35	221–241	221–241	Often higher in rear if loaded
SUV / Crossover (RAV4, CR-V)	33–36	33–38	228–248	228–262	Rear often higher for load
Light truck / pickup	35–45	45–65	241–310	310–448	Rear varies with payload
Motorcycle (typical)	28–36	33–42	193–248	228–290	Varies widely by model
Road bicycle	80–130	80–130	552–896	552–896	Tubeless runs lower
Mountain bike	20–35	22–38	138–241	152–262	Terrain dependent
Golf cart (standard)	18–22	18–22	124–152	124–152	Check tyre sidewall max
RV / Motorhome	80–110	80–110	552–758	552–758	Load-dependent; check placard
