Convert micropascal to bar
Please provide values below to convert micropascal [µPa] to bar [bar], or Convert bar to micropascal.
How to Convert Micropascal to Bar
1 µPa = 1e-11 bar
Example: convert 15 µPa to bar:
15 µPa = 15 × 1e-11 bar = 1.5e-10 bar

Micropascal
The micropascal (µPa) is a unit of pressure equal to one millionth of a pascal, used to measure very low pressures.
History/Origin
The micropascal was introduced as part of the SI unit system to quantify extremely small pressure values, especially in scientific and engineering contexts, though it is rarely used in practical applications.
Current Use
The micropascal is primarily used in scientific research, acoustics, and environmental monitoring where precise measurement of very low pressures is required.
Bar
The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.
History/Origin
The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.
Current Use
The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
