About these units
Teaspoon (US) (tsp (US))
The US teaspoon equals 4.92892 mL, though rounded to 5 mL in most practical applications. Before standardization, teaspoon sizes varied widely across households and manufacturers. With the rise of packaged foods, pharmaceuticals, and industrial recipes, the US standardized teaspoon values brought consistency to cooking and medicine. Today, the teaspoon remains the most common household unit for measuring small amounts—especially spices, extracts, and medicines.
Board Foot (board foot)
A board foot is a unit of volume used in lumber, defined as a board measuring 1 foot long × 1 foot wide × 1 inch thick, equal to 144 cubic inches, or about 2.36 liters. The unit reflects a material-centric approach to volume: rather than measuring empty space, the board foot measures solid wood content, crucial for pricing logs, boards, and woodworking materials. Forestry operations, sawmills, and lumber yards rely heavily on board-feet calculations to estimate yields from logs, determine pricing, and evaluate timber resources. The unit persists due to deep integration with North American construction and carpentry practices.
