Nanopascal Unit | All you need to know

The nanopascal (symbol: nPa) is an SI-derived unit of pressure equal to one billionth (10^-9) of a pascal. It is used in scientific research, vacuum technology, acoustics, and nanotechnology where extremely small pressure values must be measured with high precision. The nanopascal uses the SI prefix nano, representing one billionth.

One nanopascal is equal to 0.000000001 pascal, 0.001 micropascal, 1,000 picopascals, 1×10^-14 bar, and 9.86923×10^-15 standard atmosphere. The nanopascal is an important SI unit for expressing ultra-low pressure values.
