What you are seeing

Each box is one bushel of grain.

A bushel here weighs 56 lb.

1,000 bushels in total.

Metric tonnes

25.401 t

Weight in tonnes.

Pounds per bushel

56 lb/bu

The test weight used.

Kilograms

25,401 kg

Total weight in kg.

Result explanation: Bushel count

1,000 bu at 56 lb/bu.

Real-life comparison: At 60 lb/bu it would be 933 bu.

Low, normal or high? A bushel is a volume; its weight depends on the crop and test weight.

Bushels against grain weight

How to read this chart: Bushels rise in a straight line with weight. The red dot is your load.

What this calculator does

Divides the weighed pounds by the pounds in one bushel.

What your result means

1,000 bushels.

Test weight differs by crop and season.

Use the legal standard bushel weight for contracts.

The formulas

Total weight divided by the weight of one bushel.

1. Bushels from weight

bushels = weight (lb) ÷ test weight (lb/bu)

Symbols

Pounds per bushel ()

Why this formula works

A bushel is a fixed volume; each crop packs a standard weight into it.

Unit check

lb ÷ lb/bu = bu ✓

Worked example

  1. 56,000 lb of corn
  2. ÷ 56 lb/bu
  3. = 1,000 bu

Common mistakes

  • Using corn's 56 lb for soybeans (60 lb).
  • Confusing bushels (volume) with tonnes (weight).

Working for your numbers

  1. Bushels = 56,000 ÷ 56 = 1,000 bu
  2. Tonnes = 56,000 × 0.4536 ÷ 1,000 = 25.401 t

The load is about 1,000 bushels.

Frequently asked questions

Standard test weights?

Corn 56, soybean 60, wheat 60, barley 48, oats 32 lb per bushel (US standards).

Is a bushel weight or volume?

Volume — 1.244 ft³. The weight depends on the crop.

Moisture?

Contracts often adjust weight to a standard moisture; this tool does not.

Tonnes to bushels?

Multiply tonnes by 2,204.62 to get pounds, then divide by the test weight.
