Weights and measures and other interpretative data

In Canada, as a rule, the imperial system of weights and measures was followed until 1970. An exception, however, is the ton where, unless otherwise stated, the short ton of 2,000 lb. is meant.

The following table shows the weights and measures used in Canada in connection with the principal field crops and for wheat flour and fruits:

Grains Pounds Per Bushel Fruit (standard conversion) Pounds
Wheat 60 Apples, per barrel 135
Oats 34 Apples, per box 43
Barley 48 Pears, per bushel 50
Rye 56 Plums, per bushel 50
Buckwheat 48 Cherries, per bushel 50
Flaxseed 56 Peaches, per bushel 50
Corn 56 Grapes, per bushel 50
Mixed Grain 50 Pears, per box 42
All others 60 Strawberries, per quart 1.25
    Raspberries, per bushel 1.25
    Loganberries, per bushel 1.25
Note: Wheat flour: 1 barrel equals 196 pounds and approximently 4 to 5 bushels of wheat are used in the production of a barrel of flour.

Relative weights and measures, imperial and United States

The following tables of coefficients may be used to translate amounts expressed in one unit to the other or vice versa. It must be borne in mind that where the list below refers to Imperial pint, quart and gallon, their equivalent in ounces is also in Imperial measure; likewise, United States designations for these quantities are shown in the U.S. equivalent in ounces. The Imperial (or British) fluid ounce and the U.S. fluid ounce are different measures, 1 Imperial fluid ounce equalling 0.96 United States fluid ounce. Similarly, 1 Imperial gallon equals 1.2 United States gallon.

1 Imperial pint=20 fluid ounces
1 United States pint=16 fluid ounces
1 Imperial quart=40 fluid ounces
1 United States quart=32 fluid ounces
1 Imperial gallon=160 fluid ounces
1 United States gallon=128 fluid ounces
1 Imperial proof gallon=1.36 United States proof Gallon
1 short ton=2,000 pounds
1 long ton=2,240 pounds
1 barrel crude petroleum=35 Imperial gallons
