Zeptopascal Unit | All you need to know
The zeptopascal (symbol: zPa) is an SI-derived unit of pressure equal to one sextillionth (10-21) of a pascal. It is used in advanced scientific research, quantum physics, nanotechnology, and ultra-high vacuum studies where extremely small pressure values are encountered. The zeptopascal uses the SI prefix zepto, representing a factor of 10-21.
One zeptopascal is equal to 0.000000000000000000001 pascal, 0.001 attopascal, 1,000 yoctopascals, 1×10-26 bar, and 9.86923×10-27 standard atmosphere. The zeptopascal is an SI unit used for representing extremely low pressure values.
