Convert Millibar to Nanopascal (mbar to Nanopascal)

Millibar (mbar) and Nanopascal (Nanopascal) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert millibar to nanopascal. This free online calculator tool makes it simple and easy to perform the conversion from mbar unit to the Nanopascal unit.

Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.

The millibar (symbol: mbar) is a non-SI unit of pressure equal to one-thousandth of a bar or exactly 100 pascals. It has been widely used in meteorology to report atmospheric pressure and remains common in weather forecasts, although the SI unit hectopascal has largely replaced it. One millibar is numerically equal to one hectopascal. More information is available in the bar (unit) reference.

One millibar is equal to 100 pascals, 1 hectopascal, 0.1 kilopascal, 0.001 bar, and 0.000986923 standard atmosphere. The millibar remains a familiar unit for atmospheric pressure worldwide.

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.
