WEIGHT To convert from imperial to metric, multiply by the
ounces 28 grams (g) conversion factor.
pounds 0.45 kilograms (kg) For example: 10 inches x 2.5 = 25 centimetres
short tons 0.9 tonnes (t)
TEMPERATURE To convert from metric to imperial, divide by the
degrees degrees conversion factor.
Fahrenheit (F - 32) 0.56 Celsius (oC) For example: 25 centimetres ? 2.5 = 10 inches
POWER Imperial Conversions:
horsepower 750 watts (w) lb/acre x 0.0033 = oz/yd2
0.75 kilowatts (kw) gal/acre x 0.033 = oz/yd2
Useful Measurements
1 Imperial gallon = 4 quarts 1 mile = 5,280 feet
= 8 pints = 1,760 yards
= 160 fluid ounces 1 yard = 3 feet
= 10 pounds of water = 36 inches
= approx. 1.2 US gallons 1 foot = 12 inches
1 U.S. gallon = 0.8345 or approx. 5/6 Imperial gallon 1 acre = approx. 209 by 209 feet
= 8.3 pounds or 43,560 square feet.
1 Imperial pint = 20 fluid ounces = 570 mL 1 square yard = 9 square feet
1 U.S. pint = 16 fluid ounces = 475 mL 1 square foot = 144 square inches
1 pound = 16 ounces 1 mile an hour = 88 feet a minute
1 tablespoon = 3 teaspoons = 14 mL 1 cubic yd = 27 cubic feet
2 tablespoons = 1 fluid ounce = 28 mL
1 pound in Litres per hectare x 0.4 = litres per acre
100,000 gallons Kilograms per hectare x 0.4 = kilograms per acre
of water = 1 ppm (part per million)

Calculating Parts Per Million
Parts Per Million
1 per cent = 10,000 parts per million
Imperial:
1 fl. oz./gallon = 6250 ppm
1 gallon in
1,000,000 gallons of water = 1ppm
1 litre in 1,000,000 litres of water = 1ppm = 1 mL/1,000 L
Metric:
1 mg/litre (water) = 1 ppm
1 g/litre (water) = 1000 ppm
1 mL/litre = 1000 ppm

The Metric System
LINEAR MEASURES WEIGHT-VOLUME EQUIVALENTS (FOR WATER)
10 millimetres (mm) = 1 centimetre (1.00 kg) 1000 grams = 1 litre (1.00 L)
100 centimetres = 1 metre (m) (0.50 kg) 500 g = 500 mL (0.50 L)
1000 metres = 1 kilometre (0.10 kg) 100 g = 100 mL (0.10 L)
(0.01 kg) 10 g = 10 mL (0.01 L)
SQUARE MEASURES (AREA) (0.001 kg) 1 g = 1 mL (0.001 L)
100 m X 100 m = 10,000 m2
= hectare (ha) WEIGHT MEASURES
100 ha = 1 square kilometre (km2) 1000 milligrams (mg) = 1 gram (g)
1000 g = 1 kilogram (kg)
CUBIC MEASURES (VOLUME) 1000 kg = 1 tonne (t)
Dry Measure 1 mg/kg = 1 part per million (ppm)
1000 cubic millitres (mm3) = 1 cubic metre (m3)
1,000,000 cm3 = 1 cubic metre (m3) DRY - LIQUID EQUIVALENTS
Liquid Measure 1 cm3 = mL
1000 millilitres (mL) = 1 litre (L) 1 m3 = 1000 L
100 L = 1 hectolitre (hL)
