Soil Moisture Content Calculator

Compute gravimetric moisture content from wet and oven‑dry masses. Enter sample weights in grams (or any unit—just be consistent), and we’ll report moisture % and water mass.

Results

Results include: Water mass, Dry soil mass, and Gravimetric moisture content (%).

Useful Tips

Be consistent: Use the same units for wet, dry, and tare (grams recommended).
Drying protocol: Labs commonly oven‑dry at 105 °C until constant mass.
Bulk density: Moisture % here is gravimetric; volumetric requires bulk density.
Containers: Subtract the tare so you don’t overstate water mass.
