Convert bushels per acre to tonnes per hectare (bu/ac to t/ha) or back, using standard bushel weights for corn, wheat, soybeans and other crops, or your own.

Bushels are volumes, so the conversion uses the cropโ€™s standard weight per bushel.

Bushels Per Acre To Tons Per Hectare Formula

TPH = BPA ร— W ร— C

Variables:

  • TPH is the yield in metric tonnes per hectare (t/ha).
  • BPA is the yield in bushels per acre (bu/ac).
  • W is the crop weight in pounds per bushel (lb/bu).

Multiply bushels per acre by pounds per bushel to get pounds per acre. Convert pounds to kilograms using 0.45359237 kg per pound, then divide by 1,000 to get tonnes per acre. Divide by 0.40468564224 hectares per acre to get tonnes per hectare. The combined unit conversion factor C is 0.45359237 รท (1,000 ร— 0.40468564224).

How to Convert Bushels Per Acre To Tons Per Hectare?

The following steps outline how to convert the Bushels Per Acre To Tons Per Hectare.


  1. First, determine the bushels per acre. 
  2. Choose the crop or enter a custom weight in pounds per bushel.
  3. Apply the formula above to get metric tonnes per hectare. To go from t/ha to bu/ac, divide by the same crop-specific conversion factor.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

For corn at 56 lb/bu, a yield of 15 bu/ac converts to about 0.942 t/ha.

Frequently Asked Questions (FAQ)

What is a bushel?

A bushel is a unit of volume that is used in agriculture primarily in the United States to measure quantities of grain. One bushel is equivalent to approximately 35.24 liters.

Why convert bushels per acre to tons per hectare?

Converting bushels per acre to tons per hectare is useful for standardizing measurements across different regions and countries, making it easier to compare agricultural productivity and yields internationally.

Why does the conversion factor depend on the crop?

A bushel measures volume. The conversion to mass uses the weight of a bushel of the selected crop. An acre is 0.40468564224 hectares for every crop.

Can this formula be used for any type of crop?

Use the crop-specific trade weight or enter a custom weight in pounds per bushel. The measured weight of a bushel can vary with grain condition and moisture.
