- Millibar Definition & Meaning - Merriam-WebsterThe meaning of MILLIBAR is a unit of atmospheric pressure equal to 1/10₀₀ bar or 100 pascals.
- Air Pressure - National Oceanic and Atmospheric AdministrationAt sea level, standard air pressure in millibars is 1013.2. Weather maps showing the pressure at the surface are drawn using millibars. Although the changes are usually too slow to observe directly, air pressure is almost always changing.
- Atmospheric pressure - WikipediaAtmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. [2] .
- mbar相当于多少帕? - 百度知道毫巴 （简写mbar或mb）即是1/1000巴, 这是一个用于测量压力的物理单位. 1毫巴等于1帕 （hPa）. 毫巴的概念由Napier Shaw先生于1909年发明, 于1929年为国际所接受. Unicode符号为"mb": （?）. 毫巴不是SI单位. SI单位为帕斯卡（帕）, 1mbar = 100 Pa = 1 hPa = 0.1 kPa. 虽然如此, 但毫巴在很多场合仍然是一个常用单位。 帕斯卡定律只能用于液体中，由于液体的流动性，封闭容器中的静止流体的某一部分发生的压强变化，将大小不变地向各个方向传递。 压强等于作用压力除以受力面积。 根据帕斯卡定律，在水力系统中的一个活塞上施加一定的压强，必将在另一个活塞上产生相同的压强增量。
