Frequently asked questions
How accurate are the results?+
Calculations use the internationally standardized (SI) definitions; only the display is rounded to about six significant digits. That's plenty for everyday, school and work use.
Is 1 GB 1,000 MB or 1,024 MB?+
This converter uses the binary convention your operating system uses: 1 GB = 1,024 MB. Drive manufacturers use decimal (1 GB = 1,000 MB), which is why a 500 GB SSD shows up as ~465 GB on your computer.
How many GB is a movie?+
Roughly 3–7 GB per hour for 1080p streaming and 15–20 GB per hour for 4K. A phone photo runs 3–8 MB.
Does it need a fast connection?+
No. The math runs instantly inside your browser with no server round-trip — it even works offline once the page is open.
Is it really free?+
Yes. No sign-up, no install, no usage limits. The site is ad-supported.
