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

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^â3, 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".
