压强换算计算器支持多种压强单位，包括帕斯卡、巴、磅每平方英寸、大气压等。在基本压强单位、大气压单位、英制单位、真空度单位和专业分子动力学压强测量之间进行高精度换算。

常见压强单位换算：帕斯卡转巴，千帕转磅每平方英寸，标准大气压转帕斯卡，毫米汞柱转帕斯卡，巴转帕斯卡，磅每平方英寸转帕斯卡，托转帕斯卡。精确的压强单位换算工具。

原理 / 公式来源

压强 SI 单位为帕（Pa）= N/m²。bar、atm、torr、psi 等单位与 Pa 的关系来自精确定义或约定参考值。

本工具统一换算到 Pa：目标 = 源 ×（源→Pa）÷（目标→Pa）。

公式与示例

公式：目标值 = 源值 × (源→Pa) ÷ (目标→Pa)。

示例：1 atm = 101325 Pa；1 bar = 100000 Pa。

常见误差 / 注意事项

表压与绝压不同：psig 与 psia 相差一个大气压。
atm 与 bar 数值接近但不相等，不能混用。
真空/低压建议用科学计数法并提高显示精度。

实际应用场景

轮胎、泵和真空系统常混用 psi、bar、atm、Pa。

换算前务必确认是表压还是绝压。
