「巴 ↔ 帕斯卡」是什么？What is the Bar to Pascal tool?
1 bar = 100,000 Pa。支持巴、帕斯卡、千帕、兆帕互算。1 bar = 100,000 Pa. Units: bar, pascal, kilopascal, megapascal.
如何使用「巴 ↔ 帕斯卡」？How do I use the Bar to Pascal tool?
在「巴 ↔ 帕斯卡」中输入数值并选择原单位，表格会同时列出换算到所有其他单位的结果，可一键复制。Enter a value in the Bar to Pascal and choose the source unit; the table shows the value in every other unit at once, ready to copy.
1 巴和 1 个大气压一样吗？Is a bar the same as an atmosphere?
接近但不相同：1 bar = 100000 Pa（精确），1 标准大气压 = 101325 Pa，所以 1 bar ≈ 0.987 atm。工程上常用 bar，气象上常用百帕（1 hPa = 1 mbar）。Close but not equal: 1 bar = 100,000 Pa exactly and 1 standard atmosphere = 101,325 Pa, so 1 bar ≈ 0.987 atm. Engineers often use bar, meteorologists hectopascals (1 hPa = 1 mbar).
1 巴 等于多少其他单位？How much is 1 bar in the other units?
1 巴 = 100000 帕斯卡 = 100 千帕 = 0.1 兆帕（按定义系数计算，最多保留 10 位有效数字）。本页不接受负数：输入负值会提示错误。1 bar = 100000 pascal = 100 kilopascal = 0.1 megapascal (from the defined factors, up to 10 significant digits). Negative values are not accepted here and show an error.
有哪些选项可以调整？What options can I adjust?
「巴 ↔ 帕斯卡」的设置：「数值」默认 1。每次生成结果都按当前设置处理。Settings in the Bar to Pascal — "Value" default 1. The result always uses the current settings.
换算系数准确吗？Are the conversion factors exact?
「巴 ↔ 帕斯卡」采用国际单位制（SI）或公认标准中的定义值作为换算系数，结果保留约 10 位有效数字。The Bar to Pascal uses factors defined by the SI or other recognised standards and shows about 10 significant digits.
