CONVERSION FACTORS AND VERTICAL DATUM

Multiply By To obtain
acre-foot (acre-ft) 1,233 cubic meter (m3)
acre-foot per year (acre-ft/yr) 1,233 cubic meter per year (m3/yr)
foot (ft) 0.3048 meter (m)
gallon (gal) 0.00378 cubic meter (m3)
million gallons (Mgal) 3,785 cubic meter (m3)
inch (in.) 2.54 centimeter (cm)
inch per year (in/yr) 25.40 millimeter per year (mm/yr)
mile (mi) 1.609 kilometer (km)
pound (lb) 0.4536 kilogram (kg)

Temperature: Degrees Celsius (°C) can be converted to degrees Fahrenheit (°F) by using the formula °F = 1.8(°C)+ 32. Degrees Fahrenheit can be converted to degrees Celsius by using the formula °C = 0.556(°F-32).

Sea level: In this report, "sea level" refers to the National Geodetic Vertical Datum of 1929 (NGVD of 1929, formerly called Sea-Level Datum of 1929), which is derived from a general adjustment of the first-order leveling networks of the United States and Canada.
