Frequently asked questions

What can I calculate here?

Data storage sizes (MB, GB, TB), internet and transfer speeds (Mbps), download or upload times, screen and image aspect ratios, and conversions between binary, decimal, and hexadecimal.

Why do file sizes sometimes look different from my device?

Devices may use decimal (1 GB = 1,000 MB) or binary (1 GiB = 1,024 MiB) units. Check which unit a tool uses if your result differs slightly from what your operating system reports.

Are these calculators free?

Yes — free, no sign-up, and they work on any device.

How accurate are the results?

They use standard conversion factors; small differences usually come from decimal-vs-binary units or network overhead, not the math itself.
