Temperature in degrees Celsius (°C) can be converted to degrees Fahrenheit (°F) as follows:
°F = 1.8 x °C + 32

Sea level: In this report "sea level" refers to the National Geodetic Vertical Datum of 1929--a geodetic datum derived from a general adjustment of the first-order level nets of the United States and Canada, formerly called Sea Level Datum of 1929.

*Transmissivity: In this report transmissivity is expressed as meter squared per day (m2/d)--The standard unit for transmissivity (T) is cubic meter per day per square meter times meter of aquifer thickness "[(m3/d)/m2]m" or cubic foot per day per square foot times foot of aquifer thickness "[(ft3/d)/ft2]ft." These mathematical expressions reduce to meter squared per day "(m2/d)" or foot squared per day "(ft2/d)."
