Final answer:
To convert inches of mercury (inHg) to hectopascals (hPa), multiply the given value in inches of mercury by the conversion factor: 1 inHg = 33.8639 hPa.
Step-by-step explanation:
To convert inches of mercury (inHg) to hectopascals (hPa), you can use the following conversion factor: 1 inHg = 33.8639 hPa. Simply multiply the given value in inches of mercury by this conversion factor to obtain the equivalent value in hectopascals.
Example:
If you have a pressure of 20 inHg, you can convert it to hectopascals using the following calculation:
20 inHg * 33.8639 hPa/inHg = 677.278 hPa
