## Conversion Atmospheres - Millibars

atm

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

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

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

## Formula to Convert atm – mbar

In mathematical terms, to do this atmosphere to millibar conversion by hand you need to know the formula behind the calculation so we are providing it below. For instance, 4 atm = 4,053 mbar and 17 atm = 17,225.25 mbar

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

## What are atmoshperes?

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. Atmoshperic pressure is measured by the unit of atmoshpere by a piece of equipment called a barometer, which is commonly used in meteorology. Use our atmosphere – millibar converter.

## What are millibars?

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