The Corn with Moisture Weight Conversion calculator estimates the weight of an amount of corn at a lower moisture percentage based on the current weight and percent moisture, and a target moisture percentage.
INSTRUCTIONS: Choose units and enter the following:
- (H) Higher Corn Moisture Percentage
- (W) Higher Corn Moisture Weight
- (L) Lower Moisture Content Percentage
- Consider market-ready dry corn to be at 15.5% moisture
Lower Moisture Weight (LMW): The calculator returns the weight of lower moisture corn in pounds (lbs). However this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The Corn with Moisture Weight Conversion formula used to estimate the pounds of lower moisture corn used in this calculatoar is:
LMW = (100% - H)/(100%-L) * W
where:
- LMW = Weight of Lower Moisture Corn
- H = Percent Moisture of Higher Moisture Corn
- W = Weight of Higher Moisture Corn
- L = Percent Moisture of Lower Moisture Corn
The calculator used the statistical observations from an Ohio State University Extension Office report on percent moisture, shell corn vs ear corn, pounds in one bushel to convert pounds of corn with a higher moisture content to pounds of corn with a lower moisture content.
Example: Convert 10,000 lbs. of 25% moisture corn to 15.5% moisture corn
[ (100% – 25%) / (100% – 15.5%) x 10,000 lbs ]
= (75% / 84.5%) x 10,000
= 0.887574 x 10,000
= 8875.74 lbs @ 15.5% moisture
Corn Moisture
The moisture content of harvested corn depends on how and when it’s harvested, and what it’s going to be used for. Here’s the common range:
- Field Corn (for grain)
- At harvest: 18–30% moisture (often in the low 20s).
- Farmers usually start harvest when moisture drops to about 20–25% to avoid field losses.
- Grain is then dried (naturally or in a dryer) to about 13–15% moisture for safe storage.
- Silage Corn (harvested earlier for livestock feed)
- Usually harvested at 60–70% moisture (30–40% dry matter).
- Sweet Corn (for food)
- Harvested much earlier, at 70–75% moisture, to maximize sweetness and tenderness.
So for grain corn — the most common case — you can expect 18–30% moisture at harvest, with 15% or lower being the goal before it’s stored long-term.
Market Ready Grain Weights in Pounds per Bushel
- Weight of Corn - 56 lb/bu
- Weight of Wheat - 60 lb/bu
- Weight of Barley = 48 lb/bu
- Weight of Oats - 32 lb/bu
- Weight of Rye - 56 lb/bu
- Weight of Soybean - 60 lb/bu
Corn Farming Calculators:
