To convert degrees Celsius (°G) to degrees Fahrenheit (°F) use the following
formula: (°Cx9/5)+32=°F.
Suspended sediment concentrations are given only in milligrams per liter
(mg/L) because these values are (within the range of values presented)
numerically equal to concentrations expressed in parts per million.
