Byte Converter

Data

Convert between bytes, KB, MB, GB, TB in both SI and binary units

Enter a byte count and see it converted across KB, MB, GB, and TB simultaneously, with a toggle between SI (1000-based) and binary (1024-based) units, the exact distinction that explains why a "1TB" drive shows less than 1TB in your OS, which does binary math internally but keeps SI labels on the box. Cloud billing and OS-level display don't always agree either: AWS and most cloud storage pricing use SI (1000-based), while operating systems often display binary values, so it's worth checking which convention applies before comparing a provider's advertised number against your account dashboard. It focuses on byte-based units specifically; for network throughput measured in bits (Mbps), remember the 8-bits-per-byte conversion yourself since that's outside this tool's scope. All arithmetic runs locally.

How to use Byte Converter

  • 1.Enter a byte count from a file size or API response to see it converted across KB, MB, GB, and TB simultaneously.
  • 2.Switch between SI (1000-based) and binary (1024-based) units to match how your OS or cloud provider reports storage.
  • 3.Use it to sanity-check whether a "10GB" plan advertised by a provider matches the raw byte quota in your account dashboard.

Frequently asked questions

What's the difference between SI and binary units?
SI units (KB, MB, GB) use powers of 1000 per the metric system, while binary units (KiB, MiB, GiB) use powers of 1024 — this is why a "1TB" hard drive shows less than 1TB in your OS, which uses binary math but SI labels.
Which one do cloud providers use?
It varies — AWS and most cloud billing use SI (1000-based) for storage pricing, while operating systems often display binary values, so always check which convention applies before comparing numbers.
Is my data sent anywhere?
No, all conversion is simple arithmetic performed locally in your browser.
Does it support bits as well as bytes?
The tool focuses on byte-based units; for network throughput measured in bits (e.g. Mbps), remember 1 byte equals 8 bits when converting manually.
