Data & number systems

Digital storage, transfer, bases, and large-number notation.

Choose the tool whose inputs and output match your task. Check each calculator’s assumptions and limitations before using its result.

Latest update:

These tools convert digital storage and number notations for files, devices, code, and large figures. Start with the digital storage converter for bytes in decimal MB, GB, and TB or binary KiB, MiB, and GiB, matching whatever your operating system labels. The binary converter shows one integer in base 2, 10, 16, and 8 for programming and coursework. Big quantities become readable with the number to million converter, which also shows billions and thousands. Notation changes belong to the Roman numerals converter.

Frequently asked questions

How many millions are in one crore?
One crore equals 10 million. A crore is 10,000,000 in plain digits, while a million is 1,000,000. Dividing 10,000,000 by 1,000,000 gives 10, so every crore value is multiplied by 10 to express it in millions.
How does the calculator convert crore to million?
The calculator multiplies the entered crore value by 10. It also multiplies by 100 to show lakhs and multiplies the million result by 1,000,000 to show the expanded plain number, which makes the scale easier to audit before copying.
Why convert crore to million instead of lakh?
Crore to million bridges Indian and Western short-scale writing. Use it when an Indian source says a company earned 6 crore, but an investor deck, international dashboard, or English-language report wants the number in millions. Lakh is still Indian; million is the wider global label.
