Some people are very well versed with these abbreviations and their meanings, while others may recognize the terms and loosely understand them but don’t have a firm grasp on definitions. There’s also a whole host of people wondering whether TB stands for Tom Brady. 

Spoiler alert: it doesn’t. 

What is a byte?

Before we get into the title of this article and answer “how many GB in a TB,” let’s first make sure we’re all on the same page about the basics and look at bytes (this’ll come in handy later).

Put simply, a byte is a basic unit of digital information which is commonly used for storage and processing. 

Typically, a byte is made up of eight bits which are the smallest units of digital information. 

What does GB stand for? What does TB mean? What is a PB?

These ones are easier. 

A GB is a gigabyte, a TB is a terabyte and a PB is a petabyte. 

A gigabyte equates to one billion bytes, while a terabyte equals approximately a trillion bytes. 

A petabyte is huge. It’s equivalent to roughly a quadrillion bytes.

If you’re wondering about megabytes (MB), we’ve got a different article that addresses them in full.

So…how many GB in a TB?

Don’t feel like doing the math? We get it. Why multiply when you can Google? 

One terabyte is equal to 1,024 gigabytes. 

Okay, so how do I convert TB to PB?

Much like GB to TB, one petabyte is equal to 1,024 terabytes.

We’ll also save you asking the follow up: one petabyte is a million gigabytes.

Do I need to think about any of these terms when thinking about my mobile data usage?

Yes and no. A somewhat frustrating answer to be sure but in this case, it’s true.

Most of us will use over a gigabyte of data each month, so some familiarity with this term is definitely useful. 

As for terabytes, our home internet use can certainly reach TB territory but not our mobile data use.

So if you searched “how many GB in a TB” worrying about your phone usage, we’d say that you’re in the clear. 

As for petabytes, we don’t need to even think that big in the context of mobile data use.
