1 lb./acre = 1.12 kilogram/hectare

1 kilogram/hectare = 0.892 lb./acre

1 cwt/acre = 0.112 metric tons/hectare

1 metric ton/hectare = 8.93 cwt/acre

1 bushel of potatoes = 53 lbs.

1 bushel = 1.244 cu ft = 35.2 liter

1 cu ft of potatoes = about 42 lbs.

1 cwt. of potatoes = 2.38 cu ft

1 short ton = 2000 lb.

1 metric ton = 2204.6 lb.
