Atmospheres to Millibar
Convert atmospheres to millibar instantly.
About this conversion
Atmospheres (atm) equal normal air pressure at sea level: 1 atm = 101,325 Pa ≈ 1.013 bar. Millibar (mbar) er identisk med hektopascal (hPa) og bruges primært i meteorologi og vejrudsigter. Normalt lufttryk er ca. 1013 mbar. Kraftige storme kan have et kernetryk under 960 mbar. 1 Atmospheres equals 1,013.3 millibar. The converter above calculates the result instantly — you can also swap the units to convert in the other direction.
