Convert Hectopascal to Bar
Type the number of hectopascals that you wish to convert to bars.
How to Convert Hectopascals to Bars
The hectopascal and bar are both units of pressure. By definition, 1 bar equals exactly 1000 hectopascals. This means to convert hectopascals to bars, you divide by 1000.
Formula
Step-by-Step Example
Convert 5 hPa to bars:
We need to convert hectopascals to bars
Since 1 bar = 1000 hPa, divide by 1000
5 ÷ 1000 = 0.005
5 hPa = 0.005 bar

About These Units
Hectopascal (hPa)
A hectopascal (hPa) equals 100 Pascals and is identical to one millibar. Hectopascals are the standard unit for atmospheric pressure in meteorology and aviation worldwide. Standard sea level pressure is 1013.25 hPa. Weather maps display pressure in hPa.
Bar (bar)
A bar equals 100,000 Pascals or approximately 14.5 PSI. Bar is slightly less than standard atmospheric pressure (1.01325 bar). Bars measure tire pressure, compressed gas cylinders, scuba tank pressure (200-300 bar), and industrial processes.
