Crop yield and moisture calculator
Grain is traded at a standard moisture. Selling wet grain means selling water, and the buyer adjusts the weight for it.

- Weight harvested = 320
- Area = 40
- Moisture at harvest = 18
- Trading moisture = 14.5
- Specific weight = 77
- Price per tonne = 200
- dry_matter = 320 * (100 - 18) / 100 = 262.4
- Weight at trading moisture = 262.4 / ((100 - 14.5)/100) = 306.901
- Weight lost to drying = 320 - 306.901 = 13.0994
- Shrink = 320 > 0 ? 13.0994/320*100 : 0 = 4.093 57
- Yield at trading moisture = 306.901 / 40 = 7.672 51
- Yield per acre = 7.672 51 * 0.40468564224 = 3.104 96
- Bushels per acre, wheat basis = 3.104 96 * 1000 / 27.2155 = 114.088
- Revenue = 306.901 * 200 = 61 380.1
- Revenue per hectare = 40 > 0 ? 61 380.1/40 : 0 = 1534.5
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- dry matter = wet weight x (100 - moisture) / 100
- adjusted weight = dry matter / (1 - trading moisture)
Drying shrink is a real weight loss, not a penalty. The water genuinely leaves.
