**Full name:** zettapascal

**Plural form:** zettapascals

**Symbol:** ZPa

**Category type:** pressure

**Scale factor:** 1.0E+21

The SI derived unit for pressure is the pascal.

1 pascal is equal to 1.0E-21 zettapascal.

Valid units must be of the **pressure** type.

You can use this form to select from known units:

The SI prefix "zetta" represents a factor of
10^{21}, or in exponential notation, 1E21.

So 1 zettapascal = 10^{21} 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.
