Temperature in degrees Fahrenheit (°F) may be converted to degrees Celsius (°C) as °C = (°F x 32) / 1.8.

Supplemental Information

Concentrations of chemical constituents in water are given either in milligrams per liter (mg/L) or micrograms per liter (µg/L)

Frequency is given in hertz (Hz), equivalent to cycles per second.

Conductivity is given in siemens per meter (S/m).

Light-emitting diode (LED) wavelength is given in nanometers (nm; 1/1,000,000,000 meter).

Nitrate concentration is given in micromoles per liter (µmol/L)
