For those of us who need to convert teaspoons to tablespoons, tablespoons to cupfuls, and cupfuls to liters...

Equivalent Measures
3 teaspoons = 1 tablespoon 4 tablespoons = 1/4 cup 5 tablespoons + 1 teaspoon = 1/3 cup 8 tablespoons = 1/2 cup 12 tablespoons = 3/4 cup 16 tablespoons = 1 cup (8 ounces) 2 cups = 1 pint (16 ounces) 4 cups (2 pints) = 1 quart (32 ounces) 8 cups (4 pints) = 1/2 gallon (64 ounces) 4 quarts = 1 gallon (128 ounces)

Salinity

Salinity is the measure of the total salts or ion concentration and is usually reported as total dissolved solids (TDS) in milligrams per litre (mg/L). It is quicker and cheaper to measure electrical conductivity (EC) of water samples which is well correlated to total dissolved solids. The common units for EC are deciSiemens/metre (dS/m) or milliSiemens/metre (mS/m). To convert from deciSiemens/metre to milliSiemens/m multiply by 100.

Salinity measures the total salts concentration in water and includes ions such as calcium, magnesium, potassium, nitrate as well as sodium and chloride.

In Western Australia, EC in milliSiemens per metre (mS/m) is multiplied by 5.5 to obtain an estimate of TDS in mg/L.

Total Dissolved Solids (TDS) (mg/L) = EC (mS/m) x 5.5

For example water with an EC of 100 mS/m has approximately 550 mg/L or ppm of total dissolved solids. Note that 1 mg/L is equivalent to 1 part per million (ppm) and 1 gram per cubic metre (g/m 3).

The following is a general guide to water quality for overhead irrigation

Table 1: EC TDS use
EC	TDS
0-80 mS/m	0-440 mg/L	Suitable for all vegetables
80-230 mS/m	440-1,200 mg/L	Suitable for most vegetable species except the most sensetive eg. beans, radish, squash
230-550 mS/m	1,200-3,000 mg/L	Only suitable fro the more salt tolerant vegetables eg. spinach, asparagus, beetroot

ADDITIONAL:
TDS (mg/L or ppm) = 0.5X EC (dS/m or mmho/cm) = 0.5 X 100 EC (ms/cm)

1 dm/m = 100 mS/m (millisiemens per meter)
TDS (mg/L) = 5.5 X EC mS/m
