Timber Volume and Capacity Conversions

Volume Units:

Cubic Metres (m³): A metric unit of volume 1 cubic metre = 1000 litres, approximately 35.3 cubic feet.
Cubic Feet (ft³): A unit of volume used in the imperial system, commonly used in the United States and the UK. One cubic foot is equivalent to about 28.3 litres or 0.028 cubic metres.
Cubic Tons (tn³): A unit of volume often used in shipping or large volume measurements. Not to be confused with weight tons, cubic tons refer to a volumetric measurement.

Timber Measurement Units:

Francon Cubic Metres (fr.m³): A timber measurement used in some parts of Europe, often for logs or timber packages.
Hoppus Feet (h ft): The Hoppus system is an old British measurement method designed to estimate the usable volume of timber in logs, accounting for the natural taper of the log
Hoppus Superficial Feet (hs ft): Similar to Hoppus Feet but explicitly used for calculating the surface area of timber logs or planks.
Hoppus Tons (h tn): A unit used to estimate the weight of timber logs, typically used in the UK for round timber. It measures the "tonnage" or bulk of the timber.
Blodgett Feet (Bl ft): A unit used for timber measurements, especially in North America, often related to standard timber logs.
Haakondahl Superficial Feet (Hdf): An obscure and historical unit of measurement used for timber, which is not commonly used today.

Capacity and Volume for Timber:

Loads (Ld): A traditional unit of volume, typically used for large quantities of wood or logs, though the specific volume varies by region.
Cords (cd): A unit of volume for measuring firewood, traditionally in the US and Canada. One cord is a stack of wood measuring 4 feet high, 4 feet wide, and 8 feet long (128 cubic feet).
Face Cords (f cd): are similar to cords but typically refer to a stack of wood that is only one log deep, meaning the volume is less than a full cord.
Cord Feet (cd ft): A measure of wood volume related to cords, typically used to estimate larger volumes.
French Cords (cd) French: A variation of the cord used historically in France and other parts of Europe, similar in concept to the North American cord but may differ slightly in volume.
Stacks of Wood (st. wd): A general term for stacked wood, often used for firewood, where the exact volume may vary depending on local customs.

Standard Units (Timber Trade Specific):

Petrograd Standards (Ptg.std): A historical unit of measurement used in the Russian timber trade, originally from Petrograd (now St. Petersburg). Primarily used for square or round timber but is no longer in modern use.
Gothenburg Standards (Got.std): A historical timber measurement standard from Gothenburg, Sweden. It was widely used in the past for large timber trades but is now largely obsolete.
Gefle Standards (Gef.std): A historical Swedish timber measurement standard used for sawn timber and logs that is no longer widely used today.
Christiana Standards (Cri.std): A historical timber standard originating from Christiana (now Oslo), Norway, once used in international timber trade but has fallen out of use.
Drammen Standards (Drm.std): A historical Norwegian timber measurement standard for sawn or square timber. This standard is no longer used in modern timber trades.
London Standards (Lon.std): Once a British timber measurement standard for timber sold in or exported from the UK, this unit is no longer in everyday use.
Quebec Standards (Que.std): A historical timber standard used in Quebec, Canada, for sawn or square timber logs. It is rarely used in modern timber trading.
Drontheim Standards (sawn deals): A historical Norwegian timber measurement standard for sawn timber. It is no longer used in the modern timber industry.
Drontheim Standards (square timber): Historically used in Norway for square-cut logs, it is now obsolete.
Drontheim Standards (round timber): A historical standard for measuring round logs in Norway. It is no longer in use today.
Wyburg Standards (sawn deals): A historical Baltic timber measurement standard for sawn timber. It is no longer in everyday use.
Wyburg Standards (square timber): A historical measurement of square timber logs in the Baltic region. It is no longer used today.
Wyburg Standards (round timber): A historical unit for round timber logs in the Baltic region that is no longer used.
Norway Standards (Nor.std): A historical Norwegian timber measurement standard for square or sawn logs. It is no longer used in modern timber trades.
Sweden Standards (Swe.std): A historical timber measurement standard used in Sweden for sawn and unsawn logs. It has fallen out of use.
Dantzig Standards (Dan.std): A historical timber measurement standard from Dantzig (now Gdansk, Poland), once used for square or sawn timber logs. It is no longer in use.
American Standards (Am.std): A historical timber measurement standard used in the United States, often for sawn logs or large timber trades. It is no longer widely used in modern timber transactions.

Board Feet Units:

• Board Feet (bf): A unit of volume for lumber in the US and Canada. One board foot equals 144 cubic inches (1 inch thick, 12 inches wide, and 12 inches long).
• Thousand Board Feet (mbf): A unit representing 1,000 board feet used in the timber and lumber industry to measure large quantities of wood.
• Million Board Feet (mmbf): A unit representing 1,000,000 board feet, often used in large timber contracts or logging operations.

Other Timber Units:

• Riga Last (Rl square timber): An old timber measurement from Riga, Latvia, for square logs or timber.
• Riga Last (Rl round timber): A timber measurement from Riga that was used for round timber logs.
• Fathoms (pftm): A unit traditionally used to measure water depth, but it was also used in the timber industry to measure stacked wood.
• Russian Fathoms (Rus.pftm): A Russian adaptation of the fathom, used historically in timber and other industries.
• Cunits (cunit): A unit used in the forestry industry for measuring wood volume, particularly in pulpwood and woodchip production.
• Wagon Loads: A large volume measurement for timber, referring to the amount of wood that could fit on a wagon.
• Rully: A lesser-known timber measurement standard, often used regionally for specific types of wood or timber.
• Koku: A Japanese unit of volume traditionally used to measure rice but also applied to timber, especially for large logs.
