# Convert Millibars to Atmospheres

Want to convert from a quantity of pressure in millibars to atmospheres? Use this accurate and easy pressure converter fro mbar to psi for calculations!

## Conversion Millibars - Atmospheres

mbar

To measure atmospheric pressure, both millibars and atmospheres are popular units of pressure to use. They can be used in several different fields, such as meteorology and science or more commercial uses like weather forecasts. Measuring pressure at sea level is more commonly done in millibars rather than atmospheres, however recently the hectopascal is being introduced. Try this millibars to atmospheres converter or any of our other pressure converters.

## How to use the Converter for Millibars to Atmospheres?

To use this millibar to atmosphere calculator, input a quantity of millibars into the box above and click “convert” to be given an accurate equivalent in atmospheres. For the opposite calculation, convert atmospheres to millibars.

## Formula to Convert mbar – atm

In mathematical terms, to do this millibar to atmosphere conversion by hand you need to know the formula behind the calculation so we are providing it below. For instance, 15 mbar = 0.015 atm and 204 mbar = 0.2 atm

[number of] millibars / 1,013.25 = [number of] atmospheres

## What are millibars?

As a subunit of the unit of pressure called bars, the millibar is equal to exactly one-thousandth of a bar. Scientists use the measure of millibars to identify the standard atmospheric pressure at sea level to be around 1,013 millibars. Millibars are used in meteorology and for weather forecasts written for the public. Try the mbar to atm converter for your calculations.

## What are atmoshperes?

Atmoshperic pressure is measured by the unit of atmoshpere by a piece of equipment called a barometer, which is commonly used in meteorology. Atmospheres measure pressure through the force of an object exerted on a surface by the weight of the air above it, or in other terms the Earth’s atmoshpere. Use our millibar – atmosphere converter.
