Lakh and Crore to Million and Billion: 1 Lakh = 100,000, 1 Crore = 10 Million (Conversion Table)

Short answer: 1 lakh = 100,000 (one hundred thousand) and 1 crore = 10,000,000 (ten million). So 10 lakh make 1 million, 100 lakh make 1 crore, and 100 crore make 1 billion.

The two systems count the same quantities and only name them at different steps. The international system gives a new name every three zeros (thousand, million, billion); the Indian system names 10^5 (lakh) and 10^7 (crore), and in modern usage, above a crore it usually reuses those words, as in “lakh crore”.

If you need the general K, M, B and T shorthand (1K = 1,000, 1M = 1,000,000, 1B = 1,000,000,000), see 1K, 1M, 1B: how many zeros in a million, billion and trillion.

Lakh to million

To convert lakh to million, divide by 10, because 10 lakh = 1,000,000.

Each row is the lakh figure times 100,000. A quick check: the million figure is always exactly one tenth of the lakh figure; if it is not, a zero has been added or lost.

Crore to million and billion

To convert crore to million, multiply by 10. To convert crore to billion, divide by 100.

The crore figure on the left is itself often written with Indian commas: 1,00,000 crore is 100,000 crore, which is one lakh crore. Read the commas before you read the word.

Million and billion to lakh and crore

Going the other way, multiply millions by 10 to get lakh, and multiply billions by 100 to get crore.

In practice, amounts above a crore are almost always given in crore or lakh crore rather than in very large numbers of lakh, so the crore column is the one you will meet in news and reports.

How to read Indian commas

The international style puts a comma every three digits from the right. The Indian style puts the first comma after three digits from the right, and then a comma every two digits.

• 1,00,000 = one lakh = 100,000
• 12,50,000 = twelve lakh fifty thousand = 1,250,000 = 1.25 million
• 1,00,00,000 = one crore = 10,000,000
• 3,45,67,890 = three crore forty-five lakh sixty-seven thousand eight hundred ninety = 34,567,890

To convert a number written with Indian commas, remove every comma and regroup the digits in threes from the right. The digits never change, so this is the safest method when you are copying a figure into a spreadsheet or a currency converter.

Lakh crore and trillion

Above a crore, the words are combined instead of introducing a new name. One lakh crore is 1,00,000 × 1,00,00,000 = 10^12, the same as one trillion.

India’s Ministry of Finance uses this style in its budget documents. The Union Budget 2026-27 “Budget at a Glance” states that in Revised Estimates 2025-26, total expenditure is estimated at ₹49,64,842 crore (Budget at a Glance 2026-27, Ministry of Finance). Converted step by step:

The figure is in rupees, not dollars: lakh and crore, like K and M, describe only size, and the currency comes from the symbol in front.

The Reserve Bank of India also labels many statistical tables “(₹ Crore)”, for example its statistical table of liabilities and assets of SIDBI. Before comparing those numbers with a source that reports in millions or billions, multiply crore by 10 to get millions or divide by 100 to get billions.

Where you will see lakh and crore

India’s Ministry of Finance and the Reserve Bank of India publish amounts in crore, as the two documents above show.

Bangladesh uses the same words in English-language reporting. The Daily Star reported on 11 June 2026 that the finance minister unveiled “a Tk 9.38 lakh crore budget” for 2026-27 (The Daily Star). Tk 9.38 lakh crore is 9.38 × 10^12 taka, or about 9.38 trillion taka.

When you read international reports about South Asia, expect both systems in the same story: a local source quoted in crore and an international agency quoted in billions. Converting both to plain digits first avoids the most common mistake, which is treating a crore as a million (it is ten million) or a lakh as a million (it is one tenth of a million).

Common mistakes

• Treating 1 crore as 1 million. 1 crore is 10 million, so the error is a factor of ten.
• Treating 10 lakh as 10 million. 10 lakh is 1 million.
• Misreading the Indian commas in 1,00,000 crore. It is 100,000 crore, which is one lakh crore, or 1 trillion.
• Mixing the currency into the unit. ₹1 crore and Tk 1 crore are both 10,000,000 units of their own currency; to compare them you still need an exchange rate.

Frequently asked questions

How many lakhs are in a million?

Ten. One million is 1,000,000, and one lakh is 100,000, so 1 million = 10 lakh (written 10,00,000 in Indian digit grouping).

How many crores are in a billion?

One hundred. One billion is 1,000,000,000 and one crore is 10,000,000, so 1 billion = 100 crore.

How much is 1 crore in million?

1 crore = 10 million = 10,000,000. In K/M shorthand that is 10M.

How much is 1 lakh crore?

1 lakh crore = 100,000 × 10,000,000 = 10^12, which is one trillion (1T). For example, ₹49.65 lakh crore is about ₹49.65 trillion.

How do I convert lakh to million quickly?

Divide the number of lakh by 10. 25 lakh = 2.5 million; 5 lakh = 0.5 million (500K).

How do I convert crore to billion quickly?

Divide the number of crore by 100. 250 crore = 2.5 billion; 50 crore = 0.5 billion (500 million).

Why is 1,00,000 written with a comma after two digits?

In the Indian grouping, only the last three digits form one group; every group to the left of that has two digits. So one lakh is 1,00,000 and one crore is 1,00,00,000, while the international style writes 100,000 and 10,000,000. The value is the same; only the comma positions differ.
