Frequently asked questions
What is the highest point in Ohio?
Campbell Hill at 1,550 ft (472 m), from USGS, Elevations and Distances in the United States (highest and lowest elevations) (revised edition 2001).
What is the lowest point in Ohio?
Ohio River, at 455 ft, per the USGS Elevations and Distances table (2001).
What is the average elevation of Ohio?
About 923 ft (281 m): the mean of USGS 3DEP elevations at 227 points on a regular grid about 22 km apart inside the state boundary. It is our estimate, not a published figure.
Which Ohio city on this site is highest?
Columbus, at 780 ft downtown (USGS).
Does altitude affect cooking in Ohio?
At 923 ft, water boils at about 210.3 °F (99.1 °C) and standard air pressure is 28.94 inHg (980 hPa), so each breath holds about 97% of the oxygen it would at sea level. That is for the state's average elevation; check your own town, because Ohio spans 1,095 ft from lowest to highest.
