For example, a pile of logs that is 16 feet long, 8 feet wide, and 4 feet high contains approximately 4 cords of wood.

My Experience: I’ve used these formulas countless times to estimate the volume of logs and firewood. It’s a valuable skill for anyone involved in wood processing.

Estimating Drying Time Based on Moisture Content

Properly drying wood is crucial for preventing decay and ensuring that borate treatments are effective.

Moisture Content:

Moisture content is the amount of water in wood, expressed as a percentage of the wood’s dry weight.
Freshly cut wood can have a moisture content of 50% or more.
Wood that is properly dried for woodworking should have a moisture content of 6% to 8%.

Drying Time:

The drying time for wood depends on several factors, including the species of wood, the thickness of the wood, the climate, and the drying method.
Air-drying is the most common method of drying wood. It involves stacking the wood in a well-ventilated area and allowing it to dry naturally.
Kiln-drying is a faster method of drying wood. It involves placing the wood in a kiln and controlling the temperature and humidity to accelerate the drying process.

Estimating Drying Time:

As a general rule, air-drying wood takes about one year per inch of thickness.
For example, a 1-inch thick board will take about one year to air-dry, while a 2-inch thick board will take about two years.
Kiln-drying can reduce the drying time to a few weeks or even days.

Data Point: According to the Forest Products Laboratory, wood with a moisture content above 20% is susceptible to fungal decay.
