Frequently Asked Questions
What is the difference between MB and MiB?
MB is megabyte (10^6 bytes), MiB is mebibyte (2^20 bytes = 1,048,576 bytes). Binary prefixes (KiB, MiB, GiB) use powers of 2, while decimal prefixes (kB, MB, GB) use powers of 10.
How many bytes in 1 GB?
In decimal system (SI): 1 GB = 1,000,000,000 bytes. In binary system (IEC): 1 GiB = 1,073,741,824 bytes. Storage manufacturers typically use decimal, while operating systems often report binary.
Why do we need both decimal and binary prefixes?
Early computing used powers of 2 for memory addressing, leading to binary prefixes. Storage marketing adopted decimal prefixes for larger-looking numbers. This causes confusion - 500 GB advertised = ~465 GiB actual.
Is this tool accurate for very large numbers?
Yes - for typical use cases. For extremely large numbers (beyond 1e15), there may be minor precision limitations due to JavaScript Number constraints, but for everyday storage conversions it is accurate.
