# What's the difference between a megabyte and a gigabyte?

**What's the difference between a megabyte and a gigabyte?**

One megabyte is equal to 0.001 gigabytes in decimal system. In binary system, one megabyte is 0.0009765625 gigabytes. We can also say that 1 MB is 10^{-3} GB in base 10 (SI) and 2^{-10} GB in base 2. A megabyte is a unit of digital information consisting of 1,000,000 bytes, or 1,048,576 bytes. A gigabyte is a unit of computer information which is equivalent to 1,000,000,000 bytes, or 1,073,741,824 bytes.

*So, a gigabyte (GB) is one thousand times bigger than a megabyte (MB). *

**How many bytes are in one gigabyte?**

A gigabyte is a unit of digital information consists of 1,024 megabytes. One megabyte is equal to 1,000,000 bytes in decimal, and 1,048,576 bytes in binary. So when we multiply 1,024 and 1,048,576, the result will be 1,073,741,824 bytes. That means one gigabyte consists of 1,073,741,824 bytes in base two. Also, one gigabyte is equal to 1,000,000,000 bytes in base ten.

**What's bigger, a megabyte or a gigabyte?**

In a computer operating system, the value of one gigabyte is equivalent to 1,024 megabytes, as well as one megabyte is 1,024 kilobytes. Also, one gigabyte consists of 1,073,741,824 bytes of info. On the other hand, a megabyte consists of 1,048,576 bytes of info. *Finally, we can say that a gigabyte is bigger than a megabyte.*

**What is the difference between a gigabyte and terabyte?**

One gigabyte indicates a value of 1,073,741,824 bytes in binary, while one terabyte indicates a value of 1,099,511,627,776 bytes. Also, a gigabyte is 1024^{3} bytes in base 2, while a terabyte is 1024^{4} bytes.

One terabyte consists of 1,024 gigabytes of information in binary system, or 1,000 gigabytes of info in decimal system. *So, one terabyte is one thousand times bigger than a gigabyte.*
