About the Data Storage Tool
Digital storage conversion has a genuine ambiguity built into it. Storage manufacturers use decimal units where a gigabyte is 1,000,000,000 bytes, while operating systems traditionally use binary units where a gigabyte is 1,073,741,824 bytes. That 7% difference is why a 1 TB drive shows as roughly 931 GB in Windows.
This converter handles bits, bytes, kilobytes, megabytes, gigabytes, and terabytes, letting you work in whichever convention applies. Understanding which one your context uses is usually more important than the arithmetic itself.
How to Use Data Storage
- Enter the storage value.
- Select the source unit.
- Select the target unit.
- The converted value appears immediately.
When to Use This Tool
- Understanding why a drive shows less capacity than advertised
- Calculating whether files will fit within a storage quota
- Converting bandwidth or transfer figures between units
- Estimating backup sizes across different unit conventions
- Checking upload limits quoted in MB against files measured in KB
Things Worth Knowing
- A byte is 8 bits. Network speeds are usually quoted in bits per second, file sizes in bytes — a factor of eight difference.
- Binary units are formally named kibibyte, mebibyte, and gibibyte (KiB, MiB, GiB) to distinguish them from decimal ones.
- Storage manufacturers use decimal; Windows reports binary. Both are internally consistent.

Frequently Asked Questions
Why does my 1 TB drive show as 931 GB?
The manufacturer counts 1 TB as 1,000,000,000,000 bytes. Windows divides by 1024 three times, giving about 931 GiB, but labels it GB. Nothing is missing — the two are using different definitions of the same word.
What is the difference between MB and MiB?
MB in the decimal convention is 1,000,000 bytes. MiB is exactly 1,048,576 bytes. The distinct names exist precisely to remove this ambiguity, though usage remains inconsistent.
Why is my 100 Mbps connection only downloading at 12 MB/s?
Because Mbps is megabits per second and MB/s is megabytes per second. Divide by eight to convert — 100 Mbps is 12.5 MB/s, so you are getting close to the full rate.
How many bytes in a kilobyte?
1000 in the decimal convention, 1024 in the binary one. Context determines which applies — networking and storage marketing use decimal, operating systems traditionally use binary.
