Converting from Hectopascal (hPa) to Atmosphere (atm) in Pressure

What is Hectopascal (hPa)

Hectopascal (hPa) is a metric unit used to measure atmospheric pressure. It is equal to one millibar and is commonly used in weather reports.

What is Atmosphere (atm)

Atmosphere (atm) is a unit of pressure commonly used in chemistry and physics. It is the average atmospheric pressure at sea level on Earth.

Conversion Formulas

The default conversion between hPa and atm is:

1(hPa)=0.0009869233(atm)

1(atm)=1013.25(hPa)

For converting from hPa to atm, use the formula:

(atm)=(hPa)×0.0009869233

For converting from atm to hPa, use the formula:

(hPa)=(atm)×1013.25

Examples

1. Convert 4 hPa to atm:

4(hPa)×0.0009869233=0.003947693(atm)

2. Convert 13 atm to hPa:

13(atm)×1013.25=13172.25(hPa)

3. Convert 14 hPa to atm:

14(hPa)×0.0009869233=0.01381693(atm)

4. Convert 4 atm to hPa:

4(atm)×1013.25=4053(hPa)
