  "body": "\n## Summary\n\nA Borel measure on a topological space is locally finite if every point has an open neighbourhood of finite measure.\nIt may give infinite measure to the whole space, but never to a small region.\nOn locally compact Hausdorff spaces this is the same as being finite on compact sets.\nLocal finiteness is part of the definition of a Radon measure.\n\n## Explanations\n\n### L1 human\n\nLocally finite means that, around each point, a small enough window holds only a finite amount of mass.\nLength on the real line is locally finite: the whole line has infinite length, but each bounded interval has finite length.\nCounting measure on the real line is not: every open interval holds infinitely many points.\n",
