Converters for Indian numbers, land and units
India uses its own ways of writing and measuring: amounts in lakh and crore, land in bigha and katha, gold in tola. Global converters rarely handle these well. These tools do — alongside the everyday metric and imperial units.
- Number to words — write any amount in words in the Indian system, with a “Rupees … Only” line ready for cheques and invoices.
- Land area converter — convert between bigha, katha, chatak, decimal, acre, hectare, square feet and gaj, and add up deed areas like “2 bigha 5 katha”.
- Unit converter — length, weight, temperature, area, volume, speed, data and time, including tola and quintal.
Traditional land units vary from state to state, so the land converter clearly states which values it uses (currently West Bengal). For legal matters such as property deals, always confirm areas with official land records.
Remember the key links between the two number systems: 10 lakh is 1 million, 1 crore is 10 million, and 100 crore is 1 billion.
