About this calculator

Construction drawings in Nepal mix feet-inches from older practices with millimetres from newer RCC details. This converter translates length units so a 12 ft room is not entered as 12 m in the paint calculator.

Survey chains and land units (ropani/aana) are not lengths on this page — use land measurement tools.
