## ››Definition: Zeptobar

The SI prefix "zepto" represents a factor of 10-21, or in exponential notation, 1E-21.

So 1 zeptobar = 10-21 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.
