Shaw Moisture Meter Calculator
Introduction & Importance
Shaw moisture meters are essential tools for woodworkers and carpenters, helping to determine the moisture content of wood. This calculator simplifies the process, ensuring accurate and reliable results.
How to Use This Calculator
- Enter the reading from your Shaw moisture meter.
- Input the current temperature in degrees Celsius.
- Select the wood species from the dropdown menu.
- Click ‘Calculate’ to see your results.
Formula & Methodology
The calculator uses the following formula to adjust the Shaw moisture meter reading for temperature:
Adjusted Reading = (Reading – 12) / (1 + 0.002 * (Temperature – 12)) + 12
The wood species’ specific gravity is then applied to calculate the moisture content:
Moisture Content = Adjusted Reading * Specific Gravity
Real-World Examples

|---|---|---|---|---|
| 25 | 20 | Pine | 24.58 | 22.12 |
| 30 | 15 | Oak | 28.85 | 31.23 |
| 22 | 25 | Maple | 21.37 | 27.93 |
Data & Statistics
| Wood Species | Specific Gravity |
|---|---|
| Pine | 0.09 |
| Oak | 0.11 |
| Maple | 0.13 |
Expert Tips
- Always calibrate your Shaw moisture meter before use.
- Ensure the wood’s surface is clean and flat for accurate readings.
- Consider the wood’s grain direction when taking readings.
