What is 10 lakh called in the USA

10 lakh is called 1 million in the United States. The American numbering system doesn't use "lakh" at all—instead, it proceeds directly from thousands to millions. So 10,00,000 (10 lakh in Indian notation) becomes 1,000,000 (1 million in American notation).

This conversion is fundamental when communicating with American businesses, investors, or partners. If you're discussing a 50 lakh rupee transaction with American counterparts, you would present this as 5 million rupees to ensure clarity. Similarly, when reading American financial news or company reports, mentally converting millions to lakhs (by multiplying by 10) helps contextualize amounts in familiar terms. For instance, an American startup raising 10 million dollars has raised 100 lakhs or 1 crore dollars. Understanding this equivalence prevents the common error of treating millions as lakhs, which would understate values by a factor of 10 and lead to serious miscommunication in business negotiations or financial analysis.
