Is a terabyte larger than a petabyte?

No, it isn't. Let's check out the table below:

1 byte = 8 bits

1 Kilobyte = 1,000 bytes in decimal (SI)

1 Megabyte = 1,000,000 bytes in decimal (SI)

1 Gigabyte = 1,000,000,000 bytes in decimal (SI)

1 Terabyte = 1,000,000,000,000 bytes in decimal (SI)

1 Petabyte = 1,000,000,000,000,000 bytes in decimal (SI)


1 Kilobyte = 1,024 bytes in binary

1 Megabyte = 1,048,576 bytes in binary

1 Gigabyte = 1,073,741,824 bytes in binary

1 Terabyte = 1,099,511,627,776 bytes in binary

1 Petabyte = 1,125,899,906,842,624 bytes in binary


So, as you can see 1 Terabyte is equal to 1,000,000,000,000 bytes, and 1 Petabyte is equal to 1,000,000,000,000,000 bytes in the decimal system. There is also a binary system that computers use. In binary (or base 2), 1 Terabyte consists of 1,099,511,627,776 bytes, and 1 petabyte consists of 1,125,899,906,842,624 bytes. In other words, 1 Terabyte is equal to 0.001 petabytes in decimal, and 0.0009765625 petabytes in the binary system. 


So, we can say that a petabyte is 1000 times larger than a terabyte. You can also check our online and user-friendly tool here.
