Conversion Factors and Datums

Conversion Factors

Multiply By To obtain
foot (ft) 0.3048 meter
cubic foot per second (ft3/s) 0.02832 cubic meter per second
mile (mi) 1.609 kilometer
mile per hour (mi/h) 1.609 kilometer per hour

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

Discharge or flow: The rate that matter passes through a cross section of a stream channel or other water body per unit of time. The term commonly refers to the volume of water (including, unless otherwise stated, any sediment or other constituents suspended or dissolved in the water) that passes a cross section in a stream channel, flume, weir, canal, pipeline, etc., within a given period of time (cubic feet per second).

Specific conductance is given in microsiemens per centimeter at 25 degrees Celsius (µS/cm at 25°C).


Sea level: In this report, "sea level" refers to the National Geodetic Vertical Datum of 1988 (NGVD of 1988, formerly called "Sea-level Datum of 1988"), which is derived from a general adjustment of the first-order leveling networks of the United States and Canada.

Horizontal coordinate information is referenced to the North American Datum of 1983 (NAD83) unless otherwise stated.
