Convert between both decimal (SI) and binary (IEC) units. Understand the difference between GB and GiB.
Precise conversions using correct base values (1000 for decimal, 1024 for binary).
View complete conversion tables for all common data storage units in both systems.
See practical examples of file sizes and storage capacities for better understanding.
Quickly input common storage sizes like USB drives, DVDs, hard disks, and cloud storage.
All calculations are done locally in your browser. Your data never leaves your computer.
Used by storage manufacturers (hard drives, SSDs, USB drives). Based on powers of 10:
• 1 KB = 1,000 bytes
• 1 MB = 1,000,000 bytes
• 1 GB = 1,000,000,000 bytes
Used by operating systems and software. Based on powers of 2:
• 1 KiB = 1,024 bytes
• 1 MiB = 1,048,576 bytes
• 1 GiB = 1,073,741,824 bytes
Storage manufacturers use decimal to show larger capacities. Computers use binary internally. This causes the "missing space" you see when formatting drives.
A 1 TB hard drive shows as ~931 GB in Windows. This is because 1 TB (decimal) = 1,000 GB, but Windows shows 1,000,000,000,000 bytes as 931 GiB (binary).
