How this calculator works
Enter a value and choose the units. The value is converted to a base unit, then into the target unit. The table shows the same value in every data storage unit.
Formula
Result = value × (factor of "from" unit ÷ factor of "to" unit)
Example
1 GB (decimal) is about 953.67 MiB, which is why a new drive shows less space than advertised.
When to use it
- Storage and drive sizes
- Download and upload planning
- Cloud plan comparisons
Frequently asked questions
Why does my 1 TB drive show less space?
Drive makers use decimal units (1 TB = 10¹² bytes), while many operating systems display binary units, so 1 TB appears as about 931 GiB.
What is the difference between MB and MiB?
A megabyte is 1,000,000 bytes. A mebibyte is 1,048,576 bytes, or 2²⁰.
