Mar 13, 2023 · Barometric pressure is also referred to as atmospheric pressure or air pressure. In simple terms, it is the weight of the air that presses down on the earth and everything in it. The air pressing down on the earth affects weather, feeding patterns, and the behavior of fish, as well as other animals. Air is very light and almost weightless. 1 kPa = 1000 Pa = 0.01 bar. Multiply the pressure in kPa with 0.01 bar/kPa to convert kilopascals to bars: pressure in bar = 210 kPa × 0.01 bar/kPa = 2.1 bar. Verify the result with our barometric pressure conversion tool. Use this barometric pressure conversion tool when converting atmospheric pressure to a different unit.The highest barometric pressure on record was 1,083.8 MB (adjusted to sea level), measured in Agata, Siberia, on December 31, 1968.
