Timberlog - Timber calculator

Calculate timber volume in cubic metre, cubic foot volume (CFT), or board feet (CBF). Compute round timber volume from a diameter or circumference and length. Calculate sawn timber volume (planks, wooden beams,..) from the width, thickness and length. Create a list and share it over email, other sharing apps and cloud storage services for free. Create an Excel file report that can easily be imported into Excel and other spreadsheet applications.
