1 hPa = 0.000987 atm
Full precision:0.00098692 atm
Step-by-Step Solution

To convert 1 hectopascals to atmospheres, we divide by 1013.25 because one atmosphere equals exactly 1013.25 hectopascals.

1 atmosphere = 1013.25 hectopascals

Since there are 1013.25 hectopascals in every atmosphere, we divide our value by this factor:

1 ÷ 1013.25 = 0.000987 atmospheres

So 1 hectopascals = 0.000987 atmospheres.

Quick check: 0.000987 × 1013.25 = 1 hectopascals

How to Convert Hectopascals to Atmospheres

To convert hectopascals to atmospheres, divide the value by 1013.25.

The Formula

Atmospheres = Hectopascals ÷ 1013.25

Key Fact

1 atmosphere = 1013.25 hectopascals

Tip: To convert atmospheres back to hectopascals, multiply by 1013.25.

Example Conversions

Example 1: 1 hPa = 0.000987 atm
1 ÷ 1013.25 = 0.000987
Example 2: 5 hPa = 0.004935 atm
5 ÷ 1013.25 = 0.004935
Example 3: 10 hPa = 0.009869 atm
10 ÷ 1013.25 = 0.009869
