Convert between Volumetric Water Content units (m³/m³, cm³/cm³, %, L/m³, mm/m, cm/m, in/ft) and Gravimetric Water Content units (g/g, kg/kg, %, mg/g, g/kg) in two tabs. Includes a VWC↔GWC cross-conversion panel with user-specified bulk density (typical values: 1.0–1.8 g/cm³). Reference thresholds for wilting point, field capacity, and saturation included. Adjustable significant figures, scientific notation, one-click copy.

How to Use

  1. 1Select the VWC or GWC tab depending on your measurement type
  2. 2Enter a moisture value in the From field and choose the source unit
  3. 3Select the target unit in the To dropdown to see the instant result
  4. 4Expand VWC ↔ GWC cross-conversion, enter your soil bulk density (g/cm³)
  5. 5Read the calculated equivalent moisture content in the other system
  6. 6Open the Reference panel for wilting point, field capacity, and saturation thresholds
  7. 7Hover any row to copy or use as the new input
