Data Storage guide

The Data Storage Converter translates digital storage sizes between Bytes, Kilobytes, Megabytes, Gigabytes, Terabytes, and Petabytes. It uses binary prefixes (powers of 1024) standard to operating systems.

Worked examples

Convert Gigabytes to Megabytes

  1. Enter 1 as the value.
  2. Choose Gigabytes (GB) as the From unit.
  3. Choose Megabytes (MB) as the To unit.
Result: 1 GB = 1024 MB

In binary computing, 1 GB is exactly 1024 MB, because 1024 (2¹⁰) is the standard multiple.

Convert Terabytes to Gigabytes

  1. Enter 2.
  2. Choose Terabytes (TB) as the From unit.
  3. Choose Gigabytes (GB) as the To unit.
Result: 2 TB = 2048 GB

1 TB = 1024 GB, so 2 TB = 2048 GB.

Convert Bytes to Kilobytes

  1. Enter 5000.
  2. Choose Bytes (B) as the From unit.
  3. Choose Kilobytes (KB) as the To unit.
Result: 5000 B = 4.8828 KB

Because 1 KB = 1024 bytes, dividing 5000 by 1024 gives approximately 4.8828 KB.

Tips

  • •This tool uses binary standard (1 KB = 1024 B), which is what Windows and most OS file managers use.
  • •Hard drive manufacturers often use decimal standard (1 KB = 1000 B), which is why a 1 TB drive shows up as 931 GB in Windows.
  • •A lowercase "b" means bits, while an uppercase "B" means bytes. 1 Byte = 8 bits.

Frequently asked questions

What is the difference between a bit and a byte?
A bit is a single binary digit (0 or 1). A byte is a group of 8 bits. Network speeds use bits (Mbps), while file sizes use bytes (MB).
Why is 1 KB equal to 1024 bytes instead of 1000?
Computers use binary (base 2). 1024 is 2¹⁰, making it a natural fit for binary architecture, even though "kilo" technically means 1000.
What is a Megabyte (MB)?
A unit of digital information equal to 1024 Kilobytes. It is roughly the size of a high-resolution photo or a short audio clip.
What is a Gigabyte (GB)?
Equal to 1024 Megabytes. It is commonly used to measure RAM, smartphone storage, or data plans.
What is a Terabyte (TB)?
Equal to 1024 Gigabytes. It is standard for modern laptop hard drives and external SSDs.
Why does my 500 GB hard drive show up as 465 GB?
Manufacturers use decimal (500 × 1000³), but the operating system uses binary (500 × 1024³). The drive has the same number of bytes, just labeled differently.
What is a GiB?
A Gibibyte. It explicitly uses the binary definition (1024³). It is meant to resolve the confusion between decimal and binary prefixes.
What is the largest unit supported?
This tool supports Petabytes (PB). 1 PB = 1024 Terabytes.
How many bits are in a Megabyte?
1 MB = 1024 KB = 1024 × 1024 bytes = 1,048,576 bytes. Multiply by 8 to get bits (8,388,608 bits).
What is a megabit (Mb)?
A megabit is 1/8th of a megabyte. An internet speed of 100 Mbps means a maximum download speed of 12.5 MB/s.
What is a floppy disk capacity?
A standard 3.5-inch floppy disk held 1.44 MB.
Can I convert data transfer rates?
No, this tool only converts storage capacity.
Are the results rounded?
Yes, results are rounded to 6 decimal places to prevent trailing numbers from becoming unreadable.
What comes after Yottabyte?
There are theoretical units like Brontobyte and Geopbyte, but they are not currently used in practical computing.
What is a nibble?
Half a byte, or 4 bits. It corresponds to a single hexadecimal digit.
Is data storage strictly base 2?
RAM and OS file systems are base 2. Network speeds and manufacturer capacities often use base 10.
How much is 1 TB in bytes exactly?
Using binary standard, 1 TB = 1,099,511,627,776 bytes.
Can I convert between KB and KiB?
The tool uses the KB label but applies the binary (KiB) calculation, matching OS behavior.
