Soil Moisture Content Calculator
Water content from oven-dry weights — the most-run lab test on earth.
Geotechnical w divides by DRY solids — agriculture and food science divide by wet, ~17% vs 14.5% for the same sample. Cross-discipline data mixing has wrecked many a compaction spec.
Formula
Soil Moisture Content Calculator is a free moisture content soil for geotechnical engineers and foundation designers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Soil Moisture Content Calculator
Water content from oven-dry weights — the most-run lab test on earth. The calculation implements w = W_water/W_solids × 100 (NOT per wet weight) (IS 2720-2; ASTM D2216). Geotechnical w divides by DRY solids — agriculture and food science divide by wet, ~17% vs 14.5% for the same sample. Cross-discipline data mixing has wrecked many a compaction spec.
