1 Terabyte Is Equal To How Many GB?

By | February 1, 2023

1 Terabyte is equal to 1024 GB but there is more to finding the sizes of storage than answering questions in this simple manner. There is more you must know about storage devices that I will tell you right here.

According to history, the first-ever Hard Disk Drive (HDD) was made in 1956. It was as large as size a cupboard and it was nothing but lightweight with 50 24-inch disks inside and a storage capacity of 5 Megabytes. Yes!, it was just 5 Megabytes but just 6 of them could occupy the total space in a room. It was called the IBM Model 350 Disk File.

How Hard Disks are measured

The Hard Disk storage is measured in Bytes. However, to avoid having too many zeros in the unit when writing it in numbers, the measuring unit changes at every thousand and 24. You will see what I mean by that from the table below.

Bitb1 or 0 (on or off)
ByteB8 bits
KilobyteKB1024 bytes
MegabyteMB1024 kilobytes
GigabyteGB1024 megabytes
TerabyteTB1024 gigabytes
PetabytePB1024 terabytes
ExabyteEB1024 petabytes
ZettabyteZB1024 exabytes
YottabyteYB1024 zettabytes

The actual measuring unit of storage devices starts from Byte where each Byte has 8 bits. “Bit” in this storage measuring system is regarded as a binary digit. It is usually not used as a unit when measuring Hard Disk storage sizes.

As you can see, the storage unit changes after every thousand and twenty – four of the previous unit.

How many GB in 1 Terabyte?

Most people do say a thousand GB (Gigabytes) will be equal to 1 Terabyte but this is not how it is supposed to be.

Theoretically, 1 Terabyte should be the same as 1024 GB. Anything less than that will make the measuring unit of storage devices change completely.

It is also proven that most people measure storage these days using a decimal standard. The decimal standard means the 24 at the end of 1024 will be dropped. In that case, 1 Terabyte will be equal to 1000 GB.


Is 1 TB equal to 1000 GB?

Yes and No.
Yes, 1 TB is equal to 1000 GB when measuring with the decimal measuring standard since you will have to drop the 24.
No, because 1 TB is equal to 1024 GB when using the binary measuring standards. Whenever the is a question about how many GB make TB, always make sure to answer 1024 GB. That is the acceptable standard.
