High-precision pressure and stress conversion for engineering, automotive tire pressures, diving, medical blood pressure, and atmospheric meteorology. Seamlessly convert between Pa, kPa, MPa, bar, psi, atm, mmHg/Torr, and kgf/cm².
Everyday uses: setting cold tire pressure (2.5 bar = 250 kPa = 36.3 psi), reading a blood-pressure monitor, pressure-testing plumbing, and following the barometric pressure in a weather report.
Frequently asked questions
How many psi is 2.5 bar tire pressure?
2.5 bar equals approximately 36.26 psi (and 250 kPa).
What is 1 standard atmosphere (atm) in pascals?
1 atm is defined as exactly 101,325 Pa (101.325 kPa or 760 mmHg).
What is "kgf/cm²"?
1 kgf/cm² is 1 kilogram-force per square centimeter (approx. 98.07 kPa or 0.98 bar), colloquially referred to in China as "1 公斤气压".
中文说明
专业工程与日常生活压力/压强换算器:轻松互换帕斯卡(Pa)、千帕(kPa)、兆帕(MPa)、巴(bar)、磅力/平方英寸(psi)、标准大气压(atm)、毫米汞柱(mmHg / 托 Torr)以及公斤力/平方厘米(kgf/cm²)。
常用于汽车冷态胎压校准(如 2.5 bar = 250 kPa = 36.3 psi)、血压计读数、水暖管道打压与气象气压监测。
常见问题
汽车胎压 2.5 bar 等于多少 psi 和千帕?
2.5 bar 约等于 36.26 psi,严格等于 250 kPa(千帕)。
1 个标准大气压(atm)是多少?
精确等于 101,325 帕斯卡(101.325 kPa),相当于 760 毫米汞柱(mmHg)。
修车师傅常说的"打 2.5 公斤气"是什么意思?
指的是 2.5 kgf/cm²(公斤力/平方厘米),约等于 2.45 bar 或 245 kPa,与标准的 2.5 bar 极为接近。
