Convert tire pressure between PSI, BAR and kPa.
PSI, BAR and kPa are three pressure scales that convert through fixed factors, most simply remembered as one BAR equaling about 14.5 PSI or 100 kPa. Car door stickers in different countries state pressure in different units, and over- or under-inflating both hurts tire life and fuel economy.
