Frequently asked questions
How many MB are in a GB here?
1,024 — this converter uses the binary convention where each step multiplies by 1,024: 1 GB is 1,024 MB, and 1 MB is 1,024 KB, matching the example above.
Why do some tools say 1,000 instead?
Storage marketing uses decimal prefixes where kilo means 1,000, so a 1 TB drive holds about 1,000 billion bytes, not 1,024. Memory and file managers usually stick to the binary count — both camps exist by design.
What is the difference between KB and KiB?
KiB is the strict binary unit — 1,024 bytes exactly — while KB is the loose everyday label used for both 1,000 and 1,024 depending on context. This calculator follows the 1,024-style folder counts.
