Definition
A unit of cubic measurement equal to one cubic meter, used in legal and commercial contexts for the measurement of wood and other solid materials. The stere originates in the French metric system and appears in legal instruments, trade contracts, and customs documents wherever wood volume must be precisely quantified.
Common Language
Modern common usage (Wiktionary): A measure of volume used for cut wood, equal to one cubic meter.
Historical common usage (Webster's 1913): A unit of cubic measure in the metric system, being a cubic meter, or kiloliter, equal to 35.3 cubic feet, or nearly 1¼ cubic yards.
The common and legal meanings are essentially identical here, but the practical gap worth noting is one of context: in ordinary usage the stere is simply a volumetric unit, while in legal instruments it carries the additional weight of a defined trade term in contracts, tariffs, and conveyances — where ambiguity about which national standard or conversion factor applies can have binding commercial consequences.
Why It Matters in Research
Researchers working with nineteenth and early twentieth century timber contracts, customs records, or land conveyances involving French, Belgian, or Francophone Canadian jurisdictions will encounter the stere as a standard unit. Several traps arise:
First, the stere is a metric unit, but documents from jurisdictions that had not fully adopted the metric system may use it alongside non-metric measurements, requiring care when calculating equivalencies. The standard conversion is approximately 35.314 cubic feet, but older documents occasionally applied slightly different conversion factors depending on local trade practice.
Second, the stere should not be confused with the cord, the standard Anglo-American unit for measuring cut firewood (128 cubic feet, or roughly 3.62 steres). When contracts or customs schedules use both, researchers must verify which measurement controls for purposes of price, duty, or delivery obligation.
Third, the term appears most frequently in primary sources from France, Belgium, and Quebec. English-language legal documents in the United States or England rarely use the stere; its appearance in an Anglo-American instrument often signals a cross-border transaction or a contract drafted according to a civil law model.
Fourth, the stere is formally recognized under the International System of Units (SI) as a non-SI unit accepted for use, but it has been largely displaced in modern international timber trade by the cubic meter expressed without special nomenclature. Researchers reading post-1970 documents should be alert to whether "stere" and "cubic meter" are being used interchangeably or treated as distinct terms in the specific instrument.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) and Bouvier's Law Dictionary are in complete agreement on this term: both define the stere as a French measure of solidity used in measuring wood, equal to one cubic meter. Neither entry expands on conversions, trade usage, or the circumstances in which the term would appear in legal proceedings. Bouvier cross-references its MEASURE entry, which is the appropriate place to look for comparative treatment of metric and customary units in that dictionary. Neither source addresses the relationship between the stere and the cord, nor do they flag jurisdictional variation — omissions that matter for researchers working across common law and civil law source materials.
Jurisdictional Note
The stere is primarily encountered in legal sources from France, Belgium, Switzerland, and Francophone Canada. It is uncommon in English common law jurisdictions, where the cord and the cubic foot dominate timber measurement. Researchers consulting Quebec notarial records or Louisiana commercial contracts may encounter the stere as a standard term; its use in U.S. federal tariff schedules was limited and context-specific.
