About Data Storage Converter
What Is a Data Storage Converter?
A data storage converter transforms digital data size measurements between different units. Data is measured in bits and bytes, with larger units using prefixes. There are two standards: decimal (SI) where 1 KB = 1,000 bytes, and binary (IEC) where 1 KiB = 1,024 bytes. This converter handles both standards to avoid confusion between the values reported by storage manufacturers (decimal) and operating systems (often binary).
Data Size Units
Decimal: 1 KB = 1,000 B, 1 MB = 1,000 KB, 1 GB = 1,000 MB, 1 TB = 1,000 GB, 1 PB = 1,000 TB. Binary: 1 KiB = 1,024 B, 1 MiB = 1,024 KiB, 1 GiB = 1,024 MiB, 1 TiB = 1,024 GiB. The difference matters: a 500 GB hard drive (decimal) appears as about 465 GiB in the OS.
How to Use This Converter
Enter a value, select the source unit and target unit, and click Convert. Toggle between decimal and binary standards as needed.
Frequently Asked Questions
Why is my hard drive smaller than advertised?
Manufacturers use decimal (1 GB = 1,000,000,000 bytes) while operating systems use binary (1 GiB = 1,073,741,824 bytes). A 1 TB drive shows as approximately 931 GiB.
What is the difference between a bit and a byte?
A bit is the smallest unit of data (0 or 1). A byte is 8 bits. Internet speed is measured in bits per second (Mbps) while file sizes are in bytes (MB).
How many photos can 1 GB hold?
Approximately 250-300 photos at 12MP quality (3-4 MB each), or about 200 at high quality. RAW photos are larger: roughly 30-50 per GB.
