Old API ( had station absolute pressure, while the new API ( seems to only have sea level corrected pressure for a specific station. How can I convert between the two?

I would need a formula using values from the API request. Preferably the inHg and feet altitude.

PS. I've noticed that this station is reporting absolute and other stations are reporting corrected. How does Weather Underground decide what is going on and consistently report out the sea level corrected value in the new API?
