<br />Specific conductance is given in microsicmens per centimeter at 25 degrees Celsius
<br />(~tS/cm at 25 OC).
<br />
<br />Temperature: Water temperature is given in degrees Celsius (Oe), which can be converted
<br />to degrees Fahrenheit (OF) by using the following equation:
<br />
<br />OF ~ (1.8 x OC) + 32)
