Data Storage Converter Guide
Convert digital storage sizes between bytes, kilobytes, megabytes, gigabytes, and terabytes. This uses binary units (1 KB = 1024 bytes), the way file sizes are usually reported.
1 byte = 8 bits · 1 KB = 1024 bytes · 1 MB = 1024 KB · 1 GB = 1024 MB · 1 TB = 1024 GB.
How Many MB Are in a GB?
In binary terms, each unit is 1024 times the one below it, so 1 GB = 1024 MB and 1 MB = 1024 KB. To convert GB to MB, multiply by 1024; to convert MB to GB, divide by 1024.
Quick Reference Table
| Unit | Equals |
|---|---|
| 1 KB | 1024 bytes |
| 1 MB | 1024 KB |
| 1 GB | 1024 MB |
| 1 TB | 1024 GB |
Note: storage makers sometimes use decimal units (1 GB = 1000 MB), which is why a drive can show less space than advertised. Related: Time Converter and Length Converter.
