About this conversion

J.K. Rowling's Harry Potter Lexicon lists the Great Lake (Black Lake) as approximately a half-mile (0.8km) in diameter, Hogwarts Castle at about 0.25km long and the Hogwarts-to-Hogsmeade lane at about 1.2km.

These distances come from Harry Potter Lexicon (Great Lake half-mile) and fan-estimated castle grounds scale (clearly marked where fan-estimated). 1 Great Lake = 3.2×Hogwarts (0.8/0.25).

Units supported: Meters, kilometers, and Hogwarts distances (Great Lake 0.8km, Hogsmeade 1.2km).

Source note: Great Lake half-mile from Harry Potter Lexicon; other distances fan-estimated scale (clearly marked).
