About Data Storage Converter
The Data Storage Converter converts between all common digital storage units in both base-10 (SI) and base-2 (binary/IEC) systems. Enter a value in bits, bytes, kilobytes, megabytes, gigabytes, or larger units, and see all equivalents — including binary kibibytes, mebibytes, and gibibytes — simultaneously.
Understanding the difference between base-10 and base-2 units is critical in computing. Hard drive manufacturers use base-10 (1 KB = 1,000 bytes), while operating systems typically display storage in base-2 (1 KiB = 1,024 bytes). This difference explains why a "1 TB" drive shows less than 1 TiB in Windows or macOS.
All processing runs in your browser with no server calls. The converter is ideal for computer science students, IT professionals, storage planners, and anyone trying to understand why their drive capacity appears different depending on the context.

Troubleshooting
Assuming 1 GB = 1 GiB
Solution
1 GB = 1,000,000,000 bytes. 1 GiB = 1,073,741,824 bytes. They differ by about 7.4%. Hard drives advertise GB; operating systems display GiB, which is why capacity appears smaller.
Confusing megabytes (MB) with megabits (Mb) for internet speed
Solution
Internet speeds are typically quoted in megabits per second (Mbps). File sizes are in megabytes (MB). 1 MB = 8 Mb. A 100 Mbps connection downloads at approximately 12.5 MB/s.
Using base-10 storage values in binary computing contexts
Solution
When writing code that handles file sizes or memory allocation, use binary (base-2) IEC units (KiB, MiB, GiB) to match how operating systems and CPUs address memory.
Frequently Asked Questions
What is the difference between KB and KiB?
1 KB (kilobyte) = 1,000 bytes in base-10. 1 KiB (kibibyte) = 1,024 bytes in base-2. Hard drives use base-10; RAM and operating systems use base-2, which is why capacity appears different.
Why does my 1 TB hard drive show less than 1 TB in Windows?
Hard drive manufacturers use base-10 (1 TB = 10^12 bytes). Windows displays storage in base-2 (1 TiB = 2^40 bytes = 1.0995 x 10^12). So 1 TB shows as approximately 0.909 TiB in Windows.
What is a gibibyte (GiB)?
1 GiB = 2^30 bytes = 1,073,741,824 bytes. It is the binary prefix equivalent of gigabyte. The IEC standardized the "gibi" prefix in 1998 to eliminate ambiguity.
What is the largest unit supported?
The converter includes petabytes (PB) and pebibytes (PiB). 1 PB = 10^15 bytes. 1 PiB = 2^50 bytes.
How many bytes are in a megabyte?
1 MB = 1,000,000 bytes (base-10 SI definition). 1 MiB = 1,048,576 bytes (base-2 IEC definition). Most file system reports in operating systems use MiB but may label it MB for simplicity.
Is this useful for network bandwidth calculations?
Yes. Enter your file size in MB (or MiB) and the converter shows the byte count, which you can divide by your network speed in bytes per second to estimate transfer time.
What is the difference between bits and bytes?
1 byte = 8 bits. Internet speeds are typically measured in bits (Mbps), while storage sizes use bytes (MB, GB). Divide megabits by 8 to get megabytes.
Is my data private?
Yes. All conversions run entirely in your browser. No values are transmitted to any server.
