About the Data Storage Converter
Convert between bits, bytes, kilobytes, megabytes, gigabytes, terabytes and more, using either decimal or binary units.
How to use the Data Storage Converter
- Enter the Value and choose the Unit.
- Pick Decimal (1000) or Binary (1024) and press Calculate.
- Use Copy Results to copy the answers.
Formula and method
Decimal: 1 GB = 1,000 MB. Binary: 1 GiB = 1,024 MiB. 1 byte = 8 bits.
Worked example
A 500 GB drive holds about 465.66 GiB when measured the binary way, which is why computers show less space than the label.
When to use the Data Storage Converter
- Working out whether a file fits on a drive or in an email.
- Understanding why a drive shows less space than advertised.
- Converting between bits and bytes when comparing storage with network speed.
Common mistakes to avoid
- Confusing bits (b) with bytes (B). One byte is 8 bits.
- Mixing decimal (1 GB = 1,000 MB) and binary (1 GiB = 1,024 MiB) units.
Tips
- Internet speeds use bits (Mbps), while file sizes use bytes (MB).
Frequently asked questions
Why does my 1 TB drive show less than 1 TB?
Manufacturers use decimal units, while some operating systems display binary units.
How many megabytes are in a gigabyte?
1,000 in decimal units and 1,024 in binary units.
Why do internet speeds use bits?
It is a long-standing convention. Divide megabits per second by 8 to get megabytes per second.
