标准大气压（Standardatmosphericpressure）是在标准大气条件下海平面的气压，1644年由物理学家托里拆利提出，其值为101.325kPa，是压强的单位，记作atm。
化学中曾一度将标准温度和压力（STP）定义为0°C（273.15K）及101.325kPa（1atm），但1982年起IUPAC将“标准压力”重新定义为100kPa。1标准大气压=760mm汞柱=76cm汞柱=1.01325×10^5Pa=10.336m水柱。[1]1标准大气压=101325N/㎡。（在计算中通常为1标准大气压=1.01×10^5N/㎡)。100kPa=0.1MPa
地球的周围被厚厚的空气包围着，这些空气被称为大气层。空气可以像水那样自由的流动，同时它也受重力作用。因此空气的内部向各个方向都有压强，这个压强被称为大气压。
