How to Use This Calculator
  1. Weigh your paper sample as-received and record the Wet Weight (g).
  2. Oven-dry at 105°C until constant weight, then enter the Oven-Dry Weight (g).
  3. Enter your target moisture (%) and current room relative humidity (%).
  4. Review Moisture Content (%), Water Weight, and Target Wet Weight.
  5. Use EMC at Room RH and Dimensional Change (%) to plan pressroom conditioning.
