Digital storage units can get confusing fast. A file might be 850 MB, your phone may have 128 GB of storage, and a hard drive could be listed as 2 TB. When you need to compare those numbers, converting everything to the same unit makes the calculation much easier.

A memory and storage converter lets you convert between bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes in seconds.

Enter a value, select the starting unit, choose the unit you want, and you'll get the converted result.

What is a memory and storage converter?

A memory and storage converter is a calculator for digital data sizes.

Computers, smartphones, servers, websites, cloud services, and storage devices all use units such as B, KB, MB, GB, and TB. These units measure how much digital information can be stored or processed.

For example:

• 1,024 bytes = 1 KB
• 1,024 KB = 1 MB
• 1,024 MB = 1 GB
• 1,024 GB = 1 TB
• 1,024 TB = 1 PB

These values use the binary convention, which is common when discussing computer memory and operating-system calculations.

Common memory and storage units

Byte (B)

A byte is a basic unit of digital information. A single byte can represent a small amount of data, so modern files are usually measured in larger units.

You'll see bytes when working with file systems, programming, databases, and technical specifications.

Kilobyte (KB)

A kilobyte contains 1,024 bytes under the binary system.

Small text files, configuration files, and simple documents can sometimes be measured in KB.

For example, a plain text file containing a few pages may only take a few KB of storage.

Megabyte (MB)

A megabyte contains 1,024 KB.

Images, PDFs, songs, documents, and smaller videos are commonly measured in MB.

For example, a photo from a modern smartphone might be several MB depending on its resolution and compression.

Gigabyte (GB)

A gigabyte contains 1,024 MB under the binary convention.

GB is one of the most common storage units you'll see. Smartphones may have 64 GB, 128 GB, or 256 GB of storage. Computers also commonly have 8 GB, 16 GB, or 32 GB of RAM.

Terabyte (TB)

A terabyte contains 1,024 GB.

TB is commonly used for larger storage devices. External hard drives and SSDs often have capacities such as 1 TB, 2 TB, 4 TB, or more.

If you're storing large video collections, backups, databases, or many years of photos, TB is usually easier to work with than GB.

Petabyte (PB)

A petabyte contains 1,024 TB under the binary convention.

PB is mainly used for very large data collections. Large companies, research organizations, cloud providers, and data centers can deal with storage measured in petabytes.

KB to MB conversion

To convert KB to MB using the binary system, divide the number of KB by 1,024.

For example:

5,120 KB ÷ 1,024 = 5 MB

So, 5,120 KB equals 5 MB.

If you need to convert MB back to KB, multiply by 1,024.

5 MB × 1,024 = 5,120 KB

The converter handles this calculation automatically, so you don't have to calculate it manually each time.

MB to GB conversion

To convert MB to GB, divide the number of MB by 1,024.

For example:

2,048 MB ÷ 1,024 = 2 GB

So, 2,048 MB equals 2 GB.

For the reverse calculation:

2 GB × 1,024 = 2,048 MB

This can be useful when checking website files, software packages, video files, or cloud storage usage.

GB to TB conversion

GB to TB is another common conversion.

Using the binary system:

1 TB = 1,024 GB

So if you have 2,048 GB:

2,048 GB ÷ 1,024 = 2 TB

That means 2,048 GB equals 2 TB.

If you're comparing storage devices, this conversion can make the numbers easier to understand.

Why do storage sizes sometimes look different?

There's a small detail that causes a lot of confusion.

Storage manufacturers often use the decimal system. In that system:

1 KB = 1,000 bytes
1 MB = 1,000 KB
1 GB = 1,000 MB
1 TB = 1,000 GB
Computer systems may use binary measurements instead:

1 KiB = 1,024 bytes
1 MiB = 1,024 KiB
1 GiB = 1,024 MiB
1 TiB = 1,024 GiB
This difference can make a storage device appear to have less usable capacity than the number printed on its packaging.

For example, a drive advertised as 1 TB uses the decimal definition from the manufacturer. Your operating system may display its capacity using a different measurement convention.

Memory and storage aren't the same thing

RAM and storage both use units such as GB, but they have different jobs.

RAM is temporary working memory. Your computer uses it while programs are running. More RAM can let you keep more applications and browser tabs active at the same time.

Storage keeps your files for the long term. Your SSD or hard drive stores applications, photos, videos, documents, and other files even after the computer is turned off.

So a computer with 16 GB RAM and 512 GB SSD has 16 GB of working memory and 512 GB of storage capacity.

When should you use a storage converter?

A storage converter can be useful in many situations.

If you're buying an SSD, you might want to compare 512 GB, 1 TB, and 2 TB drives. If you're managing a server, you may need to convert storage limits between GB and TB.

Developers may also need conversions when working with file uploads, database limits, API responses, cloud storage, or server configurations.

It's useful for everyday tasks too. If a video is 3,500 MB and your available storage is shown in GB, converting the video size makes the comparison easier.

How the converter works

Using the tool is simple.

First, enter the amount you want to convert. Then select the original unit, such as MB or GB.

Next, select the target unit. The converter calculates the equivalent value and displays the result.

For example, if you enter 10 GB and select MB as the target unit, the result will be:

10 × 1,024 = 10,240 MB

You can then switch the target unit to TB and get:

10 ÷ 1,024 = 0.009765625 TB

The same process works for bytes, KB, MB, GB, TB, and PB.
