What is the Difference Between Megabyte Gigabyte and Terabyte?

🆚 Go to Comparative Table 🆚

The difference between megabyte, gigabyte, and terabyte lies in their size and storage capacity. Here's a comparison of these three units of measurement:

  • Megabyte (MB): A megabyte is equal to 1,024 kilobytes, where 1 kilobyte (KB) is 8 bytes. So, a megabyte has 1,024 x 1024 bytes, or approximately 1,048,576 bytes in total. Megabytes are commonly used to measure file sizes, such as photos and songs.
  • Gigabyte (GB): A gigabyte is equal to 1,024 MB. In other words, a gigabyte has 1024 x 1024 x 1024 bytes. So, a gigabyte has 1,024 x 1,024 x 1,024 bytes, or approximately 1,073,741,824 bytes in total. Gigabytes measure larger storage capacities, such as the size of RAMs or DVDs, which can take a few gigabytes.
  • Terabyte (TB): A terabyte is equal to 1,024 GB. Therefore, a terabyte has 1024 x 1024 x 1024 bytes. This results in a terabyte having approximately 1,099,511,627,776 bytes. Terabytes are used to measure very large storage capacities, such as HD videos, which can take several gigabytes, or the capacity of hard drives, which can be measured in terabytes.

In summary, a terabyte is the largest of the three units and is a measure of very large storage capacities, while a gigabyte is smaller and is used to measure larger storage capacities, and a megabyte is the smallest and is used to measure smaller file sizes, such as photos and songs.

Comparative Table: Megabyte Gigabyte vs Terabyte

Here is a table comparing the differences between megabytes (MB), gigabytes (GB), and terabytes (TB):

Unit Abbreviation Size
Megabyte MB 1,048,576 bytes
Gigabyte GB 1,024 MB
Terabyte TB 1,024 GB

To summarize:

  • 1 MB is equal to 1,048,576 bytes.
  • 1 GB is equal to 1,024 MB.
  • 1 TB is equal to 1,024 GB.

These units are used to measure digital storage capacities. For example, a standard DVD drive can hold 4.7 GB of data, while storage devices with 1,000 GB or more of capacity are measured in terabytes.
