Can someone please tell me.....???

the formula for converting millibars to hectapascals.

I'm used to reading a barometer in millibars but I don't know how to equate millibars to hectorpascals. Thanks

    Millibars ARE hectopascals (hPa)

    so 1 mb = 1 hPa

    Because I'm not studying physics, I looked up for the definitions of these units in Wikipedia, and they are as follows :

    "The bar, decibar and millibar are defined as:

    1 bar = 100 kPa (kilopascals)..." [1]

    "Milli- (symbol m) is a prefix in the SI and other systems of units denoting a factor of 10^−3, or 1/1,000." [2]

    "Hecto- (symbol h) is a SI prefix in the SI system of units denoting a factor of 10^2 (100)." [3]

    We can calculate and compare 1 millibar and 1 hectopascal based on the definitions cited above:

    1 bar = 100 kPa = 100 x 1000 Pa

    1 millibar = 1/1000 bar = (100 x 1000)/1000 Pa = 100 Pa

    1 hectopascal = 100 Pa

    So 1 millibar is identical to 1 hectopascal : 1 mbar = 1 hPa

    I hope it would help! Bye ^_^ !

    Storm Chaser 07 said it right.

    1 pascal = .01 millibar, so

    1 hectopascal = 1 millibar

    Hecto is the prefix for "hundred".
