轮胎充气压力 & 气压单位换算 All In One

bar / psi

气压单位换算

1 bar = 14.5 psi

bar

A bar (symbol: bar) is a metric unit of pressure that is defined as exactly 100,000 pascals (symbol: Pa).
It is equal to 0.987 atmospheres (101,325 Pa), the unit often used as a reference of standard pressure.

巴(符号:bar)是压力的公制单位,定义为 100,000 帕斯卡(符号:Pa)。
它等于 0.987 个大气压 (101,325 Pa),该单位经常用作标准压力的参考。

psi

A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units.
It is defined as the pressure that results when a force of one pound-force is applied to a one-square-inch area.
One psi is approximately 6,895 pascals (N/m2).

每平方英寸磅力(符号:psi)是基于常衡单位的英制美国常用压力单位。
它定义为将一磅力的力施加到一平方英寸面积上时产生的压力。
1 psi 约为 6,895 帕斯卡 (N/m2)。
