Since a perfect vacuum is technically impossible, then Earth's atmosphere technically ends where another body's atmosphere begins.
However, the internationally recognized definition limits the atmosphere to 100 km and lower. This boundary, the Karman line, is the generally accepted point at which atmospheric effects become negligible over relatively short periods of time (i.e., several hours).

Your question has no numerical answer as written. The earth's atmosphere extends outward indefinitely. At some distance you begin arguing whether it is the earth's, the moon's or the sun's.
The easiest read sources will probably be Wikipedia or Encarta.
