The nanopascal is a multiple of the unit bit for Pressure. The prefix nano (symbol n) is defined in the International System of Units (SI) as a multiplier of 1.0 × 10-9 (1 billionth, short scale), and therefore 1 nanopascal = 1.0 × 10-9 pascals = 0.000000001 pascals. The nanopascal has the unit symbol nPa.
attopascals
The attopascal is a multiple of the unit bit for Pressure. The prefix atto (symbol a) is defined in the International System of Units (SI) as a multiplier of 1.0 × 10-18 (1 quintillionth, trillionth, short scale), and therefore 1 attopascal = 1.0 × 10-18 pascals = 0.000000000000000001 pascals. The attopascal has the unit symbol aPa.
