Grain Moisture Wet/Dry Basis Calculator
Convert grain moisture content between wet basis and dry basis.
Wet basis (used in grain trade and storage) is water as a fraction of total weight; dry basis is water relative to dry matter. Dry basis = wet ÷ (100 − wet) × 100. Always confirm which basis a figure uses — they differ more at higher moisture.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

About Grain Moisture Wet/Dry Basis Calculator
Moisture content can be quoted two ways, and confusing them causes real errors in drying and trade. Wet basis — used in grain markets and storage standards — expresses water as a share of the whole grain's weight; dry basis expresses it relative to the dry matter only. This tool converts wet basis to dry basis (and shows they diverge more at higher moisture), so you always know which number you're working with.

Frequently asked questions
What's the difference between wet basis and dry basis moisture?+
Wet basis is water ÷ total weight (grain + water); dry basis is water ÷ dry matter. Grain trade and storage limits use wet basis. Dry basis is always the higher number; the two diverge as moisture rises.
Which moisture basis should I use for grain storage?+
Wet basis — all grain trading, safe-storage limits and moisture meters use wet basis. Use dry basis mainly in drying engineering calculations. This tool converts between them so you're never caught out.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline at the store/godown and your data never leaves the device.
