Table 4.18  Equivalent measurements
Length
1 in. = 2.54 cm = 25.4 mm
1 ft = 12 in. = 30.48 cm
1 yd = 3 ft = 0.914 m
1 m = 39.37 in. = 1,000 mm
1 dm = 10 cm = 100 mm
Area
1 acre = 43,560 ft² = 0.4047 ha
1 ha = 2.471 acres = 10,000
Weight
1 oz = 28.35 g
1 lb = 16 oz = 453.6 g
1 kg = 2.205 lb = 1,000 g
1 ton = 2,000 lb = 907 kg
1 metric ton = 2,205 lb = 1,000 kg
1 gal. of water = 8.34 lb = 3.78 kg
1 ft³ of water = 62.4 lb = 28.3 kg
1 mg/liter = 1mg/dm³ = 1 ppm
Volume
1 cm³ = 1 ml
1 tbsp = 3 tsp = 14.8 ml
1 fl oz = 2 tbsp = 29.6 ml
1 cup = 8 fl oz = 236.6 ml
1 pt = 16 fl oz = 473.1 ml
1 qt = 32 fl oz = 946.2 ml
1 gal. = 128 fl oz = 3785 ml
1 gal. = 3.785 liter = 231 in.³
1 liter = 33.81 fl oz = 1,000 ml
1 liter = 1.057 qt = 0.2642 gal.
1 acre-inch = 27,167 gal.
1 yd³ = 27 ft³ = 22 bu
1 bu = 1.25 ft³
1 dm³ = 1,000 cm³
Yield or Rate
1 ton/acre = 45.9 lb/1000 ft² = 41.3 lb/100 yd²
1 lb/1000 ft² = 0.9 lb/100 yd² = 0.02 ton/acre
1 lb/ft³ = 9 lb/yd³
1 kg/ha = 2 mg/dm³ = 0.89 lb/acre
