One bar equals approximately 14.5038 PSI. This conversion is frequently needed when switching between metric and imperial pressure gauges.
European gauges typically display pressure in bar, while American gauges use PSI. A tire rated at 2.3 bar in Europe reads about 33.4 PSI on an American gauge. The actual pressure is identical.
Approximately 6.895 bar equals 100 PSI. To convert PSI to bar, divide by 14.5038.
Both units can express any precision needed. Bar is standard in most international engineering and manufacturing. PSI dominates in US-based industries like oil and gas, HVAC, and automotive in North America.
