About Data Size Conversion
Convert between different units of digital information including bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and petabytes (PB). Essential for understanding file sizes, storage capacity, and data transfer requirements.
Popular Data Size Conversions
- Megabytes to gigabytes (MB to GB)
- Gigabytes to terabytes (GB to TB)
- Kilobytes to megabytes (KB to MB)
- Bytes to kilobytes (B to KB)
Frequently Asked Questions
What's the difference between GB and GiB?
GB (gigabyte) uses decimal (base 10) where 1 GB = 1,000 MB, while GiB (gibibyte) uses binary (base 2) where 1 GiB = 1,024 MiB. Our converter uses the more common decimal system.
How many MB are in 1 GB?
In the decimal system, 1 GB = 1,000 MB. However, in the binary system used by some operating systems, 1 GB = 1,024 MB. This difference can cause confusion when comparing storage capacities.
Why does my hard drive show less space than advertised?
Hard drive manufacturers use decimal (base 10) measurements, while operating systems often use binary (base 2). A 1 TB drive has 1,000 GB in decimal but shows as ~931 GB in binary calculations.
How much data does streaming video use?
Video streaming data usage varies by quality: SD uses ~1 GB/hour, HD uses ~3 GB/hour, and 4K can use 7-25 GB/hour. This helps estimate bandwidth needs and data plan usage.
What's the largest data storage unit?
Common large units include petabyte (PB = 1,000 TB), exabyte (EB = 1,000 PB), zettabyte (ZB = 1,000 EB), and yottabyte (YB = 1,000 ZB). These are used for measuring global data storage and internet traffic.
How do I calculate download time?
Download time = File size ÷ Internet speed. Remember to convert units properly: if your speed is in Mbps and file size in GB, convert GB to Mb first (1 GB = 8,000 Mb).
