What is the relationship between pascals and millipascals?

One pascal (Pa) is equal to 1000 millipascals (mPa), representing a thousandfold difference in measurement scale.

When should I use millipascals instead of pascals?

Millipascals are used for measuring very small pressure differences that whole pascals cannot accurately capture, common in precision instrumentation.

Why is millipascal not suitable for large pressures?

Because millipascal values are very small, using them for large pressures becomes impractical and less efficient than using pascals or kilopascals.
