Cable is the dry volume measure unit used to measure firewood and pulpwood in the United States and Canada.
The rope is the amount of wood that, when "tortured and stored well" (arranged so that the pieces are parallel, parallel, touch and compact), occupies a volume of 128 cubic feet (3.62 m 3 ). This corresponds to a 4-foot (122 cm) long wooden pile, 8 feet (244 cm) long, and 4 feet (122 cm) long; or other arrangement of linear measurements that produce the same volume.
The name of the cable may come from the use of cables or straps to measure it.
Cord-foot is a unit of US volume for firewood stacked, four feet long, four feet wide and one foot tall - equal to eighth from the cord. The symbol for the unit is cd-ft.

Definition
In Canada, the cable is legally determined by Canadian Measurements. The umbilical cord is one of three legal standards for the sale of firewood in Canada (piles of cubic meters, cubic feet, and cables). But the stacked cubic meters are now the preferred unit of measurement.
In the United States, the umbilical cord is determined by law in most states. National Institute of Standards and National Technology Guideline 130, section 2.4.1.2, establishing the umbilical cord and providing uniform rules for the sale of fireplaces and wood stoves. In metric systems, timber is usually measured in steres and cubic meters: 1 stere = 1 m 3 ? 0.276 cables.
Maine looks unique among U.S. states also defines "loose thrashing" or stacked firewood: "The length of the 12 or 16 inch (30 or 41 cm) cable means the amount of wood, bark and air contained in space 180 cubic feet (5.1 m 3 ), and a 24 inch (61 cm) wooden cable in length means the amount of wood, bark and air contained in a 195 cubic foot (5.5 m 3 ). [1981, c.219 (amd).] "
Other non-authorized terms for firewood volume include upright cable , kitchen cables , running cable , face cable , fencing cables , country cables , long cables , and rick , all subject to local variations. This is usually considered a well-stacked timber pile in which the log is shorter or longer than in a legal cable, to accommodate various burners. For example, the face cable generally consists of wood that is 16 inches (41 cm) long. Therefore, the face cable volume is usually 1/3 of the full rope volume despite its length of 8 feet (244 cm) and the height of 4 feet (122 cm). Facial wires are also called rick in Midwestern United States.
This term is used in other English-speaking countries, such as New Zealand, but may not have a legal definition.
The "corde" unit is used before metrics in some French-speaking countries (France, Belgium and Luxembourg), and the value varies, by region, roughly between 3 and 4 steres.

Heat value
A red oak rope (22.1 MMBtu per cable) (million thermal units per English cable) has a heating equivalent of 159 gallons US (132 gallons imperial; 602 liters) of fuel oil (138,700 Btu per Gal).
