Lakhs & Crores Converter
Convert lakhs and crores to millions, billions and rupees in one tap. Type any amount and see both comma styles, the value in words, and a digit-by-digit place-value breakdown. Exact place-value math — no exchange rate, no signup.
How it works
Lakh and crore belong to the South-Asian numbering system, while thousand, million and billion belong to the international short scale. The number itself never changes — only the unit you name it with and where the commas fall. This converter does exact place-value arithmetic: it multiplies your amount by its unit's power of ten to get the absolute number, then divides that by each other unit.
- Normalise to the absolute number. Each unit is a fixed power of ten — thousand = 103, lakh = 105, million = 106, crore = 107, billion = 109. Multiply your amount by its unit's factor. So 3.5 crore becomes 3.5 × 107 = 35,000,000.
- Re-express in every unit. Divide that absolute number by each factor: lakhs = N ÷ 100,000, crores = N ÷ 10,000,000, millions = N ÷ 1,000,000, billions = N ÷ 1,000,000,000. The result is shown trimmed of trailing zeros.
- Apply both comma styles. International grouping puts a comma every three digits (10,000,000). South-Asian grouping takes the last three digits, then groups the rest in pairs of two (1,00,00,000). Both describe the same integer.
- Format and spell it out.When “Show as Rs” is on, the same number is rendered as a rupee amount — no exchange rate is involved. The amount is also written in short-scale words (“Ten Million”) alongside the South-Asian reading (“One Crore”).
The key identities fall straight out of the exponents: a crore (107) is ten times a million (106), so 1 crore = 10 million; a crore is a hundred times a lakh (105), so 1 crore = 100 lakh; and a lakh is one-tenth of a million. Because everything is one multiplication and one division, there are no rates to go out of date and nothing to estimate. To avoid binary floating-point drift on values like 2.5 crore, the tool runs the arithmetic on whole-number integers scaled internally, then formats the result — so 2.5 crore is always exactly 25,000,000, not 24,999,999.99.
