One Hectopascal is equal to 1e+20 Attopascal.
Formula: 1 hPa = 1e+20 aPa
By using this conversion factor, you can easily convert any pressure from hectopascal to attopascal with precision.
How to Convert hPa to aPa?
Converting from hPa to aPa is a straightforward process. Follow these steps to ensure accurate conversions from hectopascal to attopascal:
- Select the Hectopascal Value: Start by determining the hectopascal (hPa) value you want to convert into attopascal (aPa). This is your starting point.
- Multiply by the Conversion Factor: To convert hectopascal to attopascal, multiply the selected hPa value by 1e+20. This factor is essential for accurately converting from a larger unit (hPa) to a much smaller unit (aPa).
- Illustration of Multiplication:
- 1 hPa = 1e+20 aPa
- 10 hPa = 1e+21 aPa
- 100 hPa = 1e+22 aPa
- Find the Conversion Result: The result of this multiplication is your converted value in attopascal unit. This represents the same pressure but in a different unit.
- Save Your Attopascal Value: After converting, remember to save the result. This value represents the pressure you initially measured, now expressed in attopascals.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the hectopascal value by 1e-20. This alternative method also gives you the correct pressure in attopascals.
- Illustration of Division:
- aPa = hpa ÷ 1e-20

Hectopascal to Attopascal Examples
Example 1:
Convert 0.7 Hectopascal to Attopascal.
Solution:
We know that one Hectopascal is equivalent to 1e+20 Attopascal.
Therefore,
0.7 hPa = 0.7 x 1e+20 aPa.
0.7 hPa = 7e+19 aPa.
Hence, 0.7 Hectopascal is approximately equal to 7e+19 Attopascal.
Example 2:
Convert 8 Hectopascal to Attopascal.
