Bytes Converter
Convert between bytes, KB, MB, GB, TB, and PB with formula breakdown
Binary (1024)
Used by operating systems (KiB, MiB, GiB)
Frequently Asked Questions
What is the difference between binary (1024) and decimal (1000) byte systems? +
Binary (base-2) uses 1024 as the multiplier: 1 KiB = 1024 bytes, 1 MiB = 1024 KiB. This is used by operating systems and RAM specifications. Decimal (base-10) uses 1000: 1 KB = 1000 bytes, 1 MB = 1000 KB. This is used by storage manufacturers and network speeds.
Why does my 1 TB hard drive show less space in Windows? +
Hard drive manufacturers use decimal (1 TB = 1,000,000,000,000 bytes), but Windows displays using binary (1 TiB = 1,099,511,627,776 bytes). So 1 TB decimal divided by 1024^4 equals about 0.909 TiB, which Windows shows as approximately 931 GB.
How many megabytes are in a gigabyte? +
In the binary system used by operating systems: 1 GiB = 1,024 MiB. In the decimal system used by manufacturers: 1 GB = 1,000 MB. For most practical purposes when dealing with files on your computer, 1 GB is approximately 1,024 MB.
What units does this converter support? +
The converter supports Bytes, Kilobytes (KB), Megabytes (MB), Gigabytes (GB), Terabytes (TB), and Petabytes (PB). You can enter a value in any unit and instantly see all other units. It supports both binary (1024-based) and decimal (1000-based) systems.
How do I calculate how many photos fit on my storage? +
Enter your storage size in the converter (e.g., 256 GB), find the result in MB, then divide by the average photo size. For example, a 256 GB drive holds about 262,144 MB (binary). With 5 MB photos, that's roughly 52,428 photos.
