The millipascal is a multiple of the unit bit for Pressure. The prefix milli (symbol m) is defined in the International System of Units (SI) as a multiplier of 1 × 10-3 (1 thousandth, short scale), and therefore 1 millipascal = 1 × 10-3 pascals = 0.001 pascals. The millipascal has the unit symbol mPa.
pascals
The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is defined as one newton per square metre.
