Overview
This converter is built for binary storage units, so the numbers you get match the way many systems describe files, memory, and disk space. Enter a value, choose the starting unit and the target unit, and the result is calculated with 1024 at each step. It is useful when you are comparing an installer to free space, checking archive sizes before copying them, or estimating how much room a backup set will need. You can move in either direction from the same form, so you can go from GB to MB, TB to GB, or KB to MB without re-entering the value. The results are especially helpful when a label, report, or file manager shows a size in a different unit from the one you need for planning. Instead of estimating by eye, you can convert the exact amount and keep the comparison consistent.
Use cases
- Check installer size against available spaceConvert a 3.7 GB setup file into MB before comparing it with a nearly full partition or USB drive.
- Estimate backup media needsTurn a 4.2 TB archive into GB to work out how many disks or cloud tiers are needed for the full copy.
- Review photo and video librariesConvert a folder of 812 MB clips into GB when organizing media before upload or transfer.
- Compare device specificationsMatch the size shown by a system, file manager, or product sheet when the values are written in different units.
How it works
- 1
Enter the number you want to convert.
- 2
Pick the source unit and target unit from KB, MB, GB, or TB.
- 3
Read the result and swap direction if you need the reverse conversion.
Examples
GB to MB
Input: 2 GB
Output: 2048 MB
Useful when a download size is easier to read in megabytes.
TB to GB
Input: 3.25 TB
Output: 3328 GB
Helpful for splitting a large backup plan into drive-sized chunks.
MB to KB
Input: 750 MB
Output: 768000 KB
Practical when a quota or transfer limit is listed in kilobytes.
FAQ
Does this tool use decimal 1000 or binary 1024?
It uses binary 1024, so 1 GB equals 1024 MB and 1 TB equals 1024 GB.
Why can my operating system show a different drive size?
Some systems and manufacturers label capacity with decimal units, while this converter follows binary units. The numbers will not match exactly when those conventions differ.
Can I convert from smaller units to larger ones?
Yes. You can convert KB to MB, MB to GB, or GB to TB, and also go back in the opposite direction.
What happens with decimal values like 1.5 TB?
Decimal input is supported, and the result is calculated from that exact value using the 1024-based scale.
What is the most common mistake when reading the result?
People often expect 1 GB to equal 1000 MB. If you read the result with a decimal assumption, the value will look too large because this tool uses 1024.
