What these tools assume
Traditional units and calendars come with conventions, and each page states the one it uses.
- The date converters cover 2000–2083 BS, the years whose month lengths are settled, and refuse dates outside that range rather than estimate them.
- The tola converter uses 11.6638 g per tola, with 16 aana and 100 lal to the tola. Some markets divide the tola differently.
- The land converter uses the standard 74-foot ropani and 270-foot bigha. It converts areas; it does not check or value a document.
Frequently asked questions
Is anything I enter sent to a server?
No. Dates, weights and land areas are converted in your browser from tables inside the page.
Why does the date converter stop at 2083 BS?
Bikram Sambat month lengths are published year by year. The sources checked agree up to 2083 BS and disagree on later years, so those years are refused until the official calendar settles them.
Are these tools only for people in Nepal?
They are written for anyone moving between Nepali and American conventions: documents dated in BS, gold weighed in tola, or land measured in ropani or bigha.
Do the converters show Devanagari?
Yes, where it is natural: month names, units and the Nepali form of a date are shown in Devanagari alongside English.
