How does the Data Storage Converter work?
This uses the decimal (SI) system: 1 KB = 1,000 bytes, 1 MB = 1,000 KB, 1 GB = 1,000 MB, 1 TB = 1,000 GB. One byte is 8 bits, so 1 byte = 8 bit. Example: 500 MB equals 500 × 1,000,000 = 500,000,000 bytes, or 0.5 GB.
Background & details
How to read the result
The converter shows the same amount of storage in a different unit. The key point: the base is always the byte, and this tool uses the decimal SI system with a factor of 1,000. That is exactly the system hard-drive, SSD and USB-stick makers print on the box. It is also why a "1 TB" drive often shows up as roughly 931 GB in your operating system – Windows counts in binary (1,024), the manufacturer in decimal (1,000).
What sizes are typical?
- A phone photo: 2–5 MB
- A song (MP3): 3–8 MB
- One hour of music streaming: about 50–150 MB
- An HD movie: 3–8 GB, in 4K quickly 20–50 GB
- One hour of Netflix in HD: around 3 GB
With these reference points you can easily judge whether your data plan or storage is enough.
Common mistakes
The classic trap is confusing bits and bytes. Internet plans advertise "100 Mbps", but files are measured in megabytes (MB). Because 1 byte = 8 bits, a 100-Mbit line downloads only about 12.5 MB per second at best. Second mistake: mixing decimal and binary units. "MB" (1,000) and "MiB" (1,024) look alike but drift apart noticeably at large sizes.
Practical tips
To estimate your phone's data use, enter the size of one typical activity (e.g. 150 MB per hour of streaming) and scale it up. When buying a memory card or drive, expect to lose 5–7 % of the advertised figure – that is roughly what the binary display plus formatting "swallows". And when you buy cloud storage, check whether the provider means GB (decimal) or GiB (binary).
Where the converter stops
For quick conversions between byte, KB, MB, GB and TB it is ideal. If you need exact binary values (KiB, MiB, GiB) – for programming or RAM specs – you have to use the factor 1,024 instead of 1,000. But for everyday life, data plans and storage purchases, the decimal system here is exactly right.
