# How many MBs are there in a GB, TB and PB?

What is a Megabyte (MB)?

A Megabyte (MB) is a unit of data measure equal to 1,024 KBs or 1,048,576 Bytes in binary.

What is a Gigabyte (GB)?

A Gigabyte (GB) is equal to 1,024 MBs or 1,048,576 KBs in base 2. Gigabyte is the most popular unit of data measure in the web hosting industry. For example, you need 700 megabytes to 1.5 gigabytes (3 - 5GB for an HD film) space to download an average movie. Today files are mostly stored in gigabytes or megabytes. If you buy an iPhone, iPad, or iPod touch, it comes with a set storage capacity ranging from 16 to 512GB for iPhone, 16GB to 1TB for iPad, and 8 to 256GB for iPod touch.

What is a Terabyte (TB)?

A Terabyte is a unit of data measure which is equal to 1,024 GBs or 1,048,576 MBs in binary system. One terabyte is enough for 500 hours worth of film. Today individual external hard drives have mostly 1 TB storage capacities. That means 1,000 GB of data. 1 TB equals to 1,000 gigabytes (GB) or 1,000,000 megabytes (MB) in decimal system. One terabyte space can hold 250 movies or 500 hours of HD video or 6.5 million document pages.

What is a Petabyte (PB)?

A petabyte (PB) is a unit of digital information storage equal to 1,024 terabytes or 1,048,576 GB (in binary). One petabyte is enough to store 57 years worth of film.

Finally we can say that:

1 GB = 1000 MB (in decimal)

1 GB = 1024 MB (in binary)

1 TB = 1,000,000 MB (in decimal)

1 TB = 1,048,576 MB (in binary)

1 PB = 1,000,000,000 MB (in decimal)

1 PB = 1.073.741.824 MB (in binary)
