About

Misreading a figure because of numbering system confusion costs real money. The Indian numbering system groups digits by lakhs and crores (1 Crore = 10,000,000), while the International system groups by millions and billions (1 Million = 1,000,000). A single misplaced comma can inflate or deflate a reported value by a factor of 10. This converter handles the arithmetic precisely: 1 Crore = 10 Million, and 1 Million = 0.1 Crore. It also renders outputs in both Indian-style grouping (1,00,00,000) and International-style grouping (10,000,000) so you can copy the correct format directly into financial documents, reports, or pitch decks without manual re-formatting.

The tool assumes exact mathematical equivalence. It does not perform currency exchange. 5 Crore INR is 50 Million INR, not 50 Million USD. If you need currency conversion, apply the exchange rate separately after converting the unit scale. Pro tip: when reading Indian financial statements for international investors, always clarify whether "Crore" refers to the count unit or is shorthand for "Crore Rupees."

Formulas

The Indian and International numbering systems differ only in digit grouping, not in magnitude. Both represent identical absolute values. The conversion factor derives from the ratio of their base units.

M = C × 10

Where M = value in Millions, C = value in Crores. The factor 10 arises because:

1 Crore = 10⁷ = 10,000,000

1 Million = 10⁶ = 1,000,000

10⁷10⁶ = 10

For the reverse conversion:

C = M × 0.1

Extended relationships across both systems:

1 Lakh = 10⁵ = 0.1 Million

1 Crore = 100 Lakh = 10 Million = 0.01 Billion

1 Arab = 100 Crore = 1 Billion

Frequently Asked Questions

The discrepancy arises from different digit-grouping conventions. In the Indian system, digits group after the first three as pairs: 1,00,00,000. In the International system, they group in threes: 10,000,000. Both represent 10⁷. Since 1 Million = 10⁶, the ratio is 10⁷ ÷ 10⁶ = 10.

No. This tool converts number scale units, not currencies. 5 Crore INR equals 50 Million INR. To obtain USD, you must multiply by the current INR/USD exchange rate separately. The converter is currency-agnostic.

JavaScript handles numbers safely up to 2⁵³ − 1 (approximately 9 × 10¹⁵), which is about 90,00,00,000 Crore or 9 Quadrillion. Beyond this threshold, floating-point precision degrades. For values exceeding this, use arbitrary-precision libraries.

1 Lakh = 100,000 = 0.1 Million. 100 Lakh = 1 Crore. 1 Arab = 100 Crore = 1 Billion. The Indian system scales in factors of 100 after the initial 1,000 (Thousand → Lakh → Crore → Arab → Kharab), while International scales in factors of 1,000 (Thousand → Million → Billion → Trillion).

India's Companies Act, SEBI regulations, and the Reserve Bank of India mandate financial reporting in Lakhs and Crores per the Indian numbering convention. This is codified in Schedule III of the Companies Act, 2013. International subsidiaries or dual-listed companies often provide both formats. When reading Indian 10-K equivalents (Annual Reports), always check whether figures are in Crore, Lakh Crore, or absolute values.

The converter preserves up to 6 significant decimal places. For instance, 0.0035 Crore converts to 0.035 Million (35,000 in absolute terms). Trailing zeros are trimmed. If your input has more than 15 significant digits, JavaScript's IEEE 754 double-precision may introduce rounding artifacts of approximately ±1 in the last digit.
