Canadians frequently need to convert inches to centimetres when reading US product listings, assembling imported furniture, or working in trades that blend imperial and metric tools. Canadian building codes are metric, but legacy blueprints and US lumber sizes still use inches.
Lumber sold in Canada is still described in "nominal" imperial sizes (2×4, 2×6) even though the actual dimensions are in millimetres. A "2×4" is actually 38 mm × 89 mm. Screen sizes for TVs, monitors, and phones are universally quoted in inches across Canada, as in the US.
