Wind speeds in building
Building codes (ASCE 7 / IRC) set a design wind speed for each location in mph — 115 mph (185 km/h) is common inland, higher on hurricane coasts. Roofing, windows and fasteners are rated against those numbers, so if a product data sheet lists km/h, convert it before comparing. The roofing calculator estimates shingle bundles.
