It was during the computations of the northeastern observations that Radhanath had calculated the height of Peak XV at exactly 29,000 ft (8839 m), but Waugh added an arbitrary two feet because he was afraid that the Sikdar’s figure would be considered a rounded number rather than an accurate one. He officially announced this finding in March 1856, and this remained the height of Mount Everest till an Indian survey re-calculated it to be 29,029 ft or 8848 m in 1955.
