Question 1

What is the difference between KB and KiB?

Accepted Answer

KB (kilobyte) traditionally means 1000 bytes in decimal (SI) units, while KiB (kibibyte) means exactly 1024 bytes in binary units. This tool supports both — pick Decimal (1000) for storage manufacturers and Binary (1024) for Windows and RAM.

Question 2

How many MB are in a GB?

Accepted Answer

In decimal (SI) units, 1 GB = 1000 MB. In binary units, 1 GiB = 1024 MiB. Hard drive makers use decimal, while Windows shows binary — which is why a 500 GB drive shows as about 465 GB in Windows.

Question 3

Is this data storage converter free?

Accepted Answer

Yes, completely free. All conversions run in your browser — nothing is uploaded to any server.
