Features:
- 80+ Wood Log Rules
- Log Volume Calculation Export result for printing and sharing
- Log Length Calculation based on wood density, log weight and mid-diameter or circumference
- Log Volume Calculation from wood density, log length and mid-diameter or circumference
- Calculation of Wood Density from log weight, log length and mid-diameter or circumference
- Share calculations with friends and colleagues
- Set imperial/metric units ( Lb, Ft, In, Lb/Ft³ or Kg, M, Cm, Kg/M³ )
- Saving the density of frequently used timber
- Commercial wood species database ( density, specific gravity, hardness, shrinkage, ... ). 
This database contains the means density. The density of wood differs depending on tree species and tree growth environment. For most species the literature thus gives a range with low, medium and high values.

- Unit Converter ( length, weight, area, volume, density )
- Share your unit converter results with friends and colleagues
