Converting from Atmosphere (atm) to Millibar (mbar)

What is Atmosphere (atm)

An atmosphere (atm) is a unit of pressure defined as the force exerted by the weight of the Earth's atmosphere on a given surface area. One atm is equal to approximately 1013.25 millibars.

What is Millibar (mbar)

A millibar (mbar) is a metric unit of pressure equal to one thousandth of a bar. It is commonly used in meteorology to measure atmospheric pressure. One millibar is equivalent to 0.0009869233 atmospheres.

Conversion Formulas

To convert from atmospheres to millibars, you can use the following formula:

Pressure in mbar=Pressure in atm×1013.25

To convert from millibars to atmospheres, use this formula:

Pressure in atm=Pressure in mbar×0.0009869233

Examples

• Converting 10 atmospheres to millibars:

10 atm=10×1013.25=10132.5 mbar

• Converting 17 millibars to atmospheres:

17 mbar=17×0.0009869233=0.0167777 atm

• Converting 4 atmospheres to millibars:

4 atm=4×1013.25=4053 mbar

• Converting 4 millibars to atmospheres:

4 mbar=4×0.0009869233=0.003947693 atm
