常见问题
如何将 PSI 转换为 bar？
To convert PSI (pounds per square inch) to bar, multiply by 0.0689476. For example, 30 PSI = 30 × 0.0689476 = 2.07 bar. To convert bar to PSI, multiply by 14.5038 (1 bar = 14.5 PSI).
bar 与 atmosphere 有何区别？
1 bar = 100,000 pascals (Pa), while 1 atmosphere (atm) = 101,325 Pa. The difference is about 1.3%. Bar is rounded metric, while atmosphere is based on average sea-level air pressure. 1 atm ≈ 1.013 bar.
什么是 mmHg，为什么在医学中使用？
mmHg (millimeters of mercury) measures pressure as the height of mercury column it can support. 1 mmHg = 133.322 Pa. It's used in medicine (blood pressure) and meteorology because mercury barometers were historically standard measurement devices.
一个 atmosphere 包含多少 pascal？
一个标准 atmosphere (atm) 精确定义为 101,325 pascals (Pa) 或 101.325 kilopascals (kPa)。这代表平均海平面大气压，是许多压力计算的基础。
什么是 torr，它与 mmHg 有何关系？
A torr is very close to mmHg: 1 torr = 1/760 of an atmosphere = 133.322 Pa, while 1 mmHg = 133.3224 Pa. The difference is negligible for most purposes. Both are used in vacuum technology and scientific applications.
