What is millibar?

A millibar is a pressure unit equal to one thousandth of a bar. It is the standard unit for atmospheric pressure in meteorology and weather forecasting, particularly in aviation and marine contexts.

What is megapascal?

A megapascal is a pressure unit equal to one million pascals. It is used for measuring high pressures in industrial hydraulics, structural materials testing, and deep-sea and geological applications.

Worked examples

1 millibar = 0.0001 megapascal

1 megapascal = 1,000,000 pascal
