## What is LogClimber?

Offline wood log calculator, unit converter and commercial timber species database. 

LogClimber provides simple and advanced mathematical functions to calculate log volume ( 80+ wood log rules ), length, weight and wood density. You can share your calculations with friends and colleagues. This application is intended solely for comparing and supporting or verifying calculations using formulas and tables.

Unlimited use for 10 days in the free version.

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
