FAQ
Is anything sent to a server?
No. Every conversion is plain maths done in your browser, so nothing you type is uploaded. The converter works offline and keeps your numbers private.
How accurate are the conversions?
They use internationally standard conversion factors (for example 1 inch = exactly 2.54 cm, 1 pound = 0.45359237 kg). Results are shown to about 10 significant figures, which is well beyond everyday precision.
What’s the difference between MB and MiB for data storage?
MB is decimal (1 MB = 1,000,000 bytes) and is what drive makers and networks use; MiB is binary (1 MiB = 1,048,576 bytes) and is what operating systems often show. This converter includes both families so you can move between them.
Can it convert number bases like binary and hex?
Yes. Choose “Number base” to convert between binary, octal, decimal and hexadecimal. It uses exact big-integer maths, so even very large numbers convert without rounding.
