## ››Definition: Hectobar

The SI prefix "hecto" represents a factor of 102, or in exponential notation, 1E2.

So 1 hectobar = 102 bars.

The definition of a bar is as follows:

The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals). The word bar is of Greek origin, báros meaning weight. Its official symbol is "bar"; the earlier "b" is now deprecated, but still often seen especially as "mb" rather than the proper "mbar" for millibars.

## ››Definition: Attopascal

The SI prefix "atto" represents a factor of 10-18, or in exponential notation, 1E-18.

So 1 attopascal = 10-18 pascals.

The definition of a pascal is as follows:

The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.
