Calculation breakdown
- Conversion
- Result = value × (from unit's kilopascals) ÷ (to unit's kilopascals)
Worked example
A tyre pressure of 220 kPa is approximately 31.9 PSI.
Assumptions
- Uses standard atmosphere and exact PSI-to-kPa conversion factors.
How this calculator works
This calculator converts a pressure value between kilopascals, bar, PSI (pounds per square inch) and standard atmospheres. Kilopascals and bar are common on Australian tyre placards and gauges, while PSI appears on imported tools, camping gear and some tyre pumps, making conversions useful when equipment uses different scales.
Frequently asked questions
What unit is Australian tyre pressure usually shown in?
Australian vehicle tyre placards typically show pressure in kilopascals (kPa), though many pumps and gauges also display PSI.
How many kPa are in 1 PSI?
One PSI equals approximately 6.895 kilopascals, a useful conversion when comparing an imported pressure gauge to local specifications.
What is a bar in pressure terms?
A bar is a metric pressure unit roughly equal to atmospheric pressure at sea level, commonly used for bike tyres and some equipment.
