Exabytes to Terabytes Converter

How to Convert Exabytes to Terabytes

To convert a data storage measurement from exabytes to terabytes, multiply the value by the conversion factor. Since one exabyte is equal to 1,048,576 terabytes, you can use this formula:

The data storage in terabytes is equal to the exabytes multiplied by 1,048,576.

How Many Terabytes Are in a Exabyte?

There are 1,048,576 terabytes in one exabyte.

What Is a Exabyte?

The exabyte (symbol: EB) is a unit of digital information equal to 2⁶⁰ bytes (approximately 1.153 quintillion bytes) in the binary system, or 1,000,000,000,000,000,000 bytes in the decimal system. Exabytes represent some of the largest data quantities in existence. The total amount of data created, captured, and replicated worldwide is estimated to be hundreds of exabytes per year, with projections reaching into the zettabyte range. This "global datasphere" encompasses enterprise data, consumer media, IoT sensors, scientific instruments, and more. Major cloud providers like Amazon Web Services, Microsoft Azure, and Google Cloud collectively store many exabytes of customer data across their global data center networks. The total storage capacity deployed worldwide is measured in zettabytes (1 ZB = 1,024 EB). To put an exabyte in context: one exabyte could hold approximately 11 million hours of 4K video, the entire Netflix catalog thousands of times over, or roughly five times all the words ever spoken by humanity. An exabyte equals 1,024 petabytes, or about one million consumer hard drives.

One exabyte is equal to:

• 2⁶⁰ bytes (≈ 1.153 quintillion bytes)
• 1,024 petabytes (PB)
• 1,048,576 terabytes (TB)
• 8 exabits (Eb)

What Is a Terabyte?

The terabyte (symbol: TB) is a unit of digital information equal to 2⁴⁰ bytes (approximately 1.1 trillion bytes) in the binary system, or 1,000,000,000,000 bytes in the decimal system. Terabytes are the standard unit for expressing the capacity of modern hard drives and large data sets. Consumer hard drives and SSDs commonly come in 1 TB, 2 TB, 4 TB, and 8 TB capacities. Enterprise-grade SSDs can reach 30 TB or more. External backup drives typically range from 1–5 TB. To put a terabyte in perspective: 1 TB can hold approximately 250,000 photos (at 4 MB each), 500 hours of HD video, 6.5 million document pages, or about 250 full-length movies. The entire printed collection of the US Library of Congress is estimated at about 10 TB. In cloud computing, storage is commonly provisioned in terabytes. Small to medium businesses might use 1–10 TB of cloud storage, while large enterprises can use hundreds of terabytes. Consumer cloud storage plans typically offer 1–2 TB per account.

One terabyte is equal to:

• 2⁴⁰ bytes (≈ 1.1 trillion bytes)
• 1,024 gigabytes (GB)
• 1,048,576 megabytes (MB)
• 8 terabits (Tb)
• 1/1,024 petabytes (PB)

Understanding Data Storage Units

Data storage units measure the amount of digital information that can be stored, transmitted, or processed. The fundamental unit is the bit (binary digit), which can hold a value of 0 or 1. All digital information, from text documents to 4K videos, is ultimately represented as sequences of bits.

Data storage units are organized in two main hierarchies: bits (b, kb, Mb, Gb, Tb, Pb, Eb) and bytes (B, kB, MB, GB, TB, PB, EB). The relationship between them is that 1 byte = 8 bits. Bits are typically used for data transfer rates (internet speed), while bytes are used for storage capacity (file sizes, drive capacity).

Binary vs. Decimal Prefixes

There are two conventions for data storage prefixes, which can cause confusion:

• Binary (base-2): Each prefix step is a factor of 1,024 (2¹⁰). So 1 kB = 1,024 B, 1 MB = 1,024 kB, etc. This is used by operating systems and in most computing contexts. This converter uses the binary convention.
• Decimal (base-10): Each prefix step is a factor of 1,000. So 1 kB = 1,000 B, 1 MB = 1,000 kB, etc. This is used by storage device manufacturers and in telecommunications.

To avoid confusion, the IEC introduced binary prefixes: kibibyte (KiB = 1,024 B), mebibyte (MiB = 1,024 KiB), gibibyte (GiB = 1,024 MiB), etc. However, these names are not widely used in everyday language.

Common Data Sizes in Perspective

• 1 Bit: A single binary digit (0 or 1)
• 1 Byte (8 bits): One text character (ASCII)
• 1 Kilobyte (1,024 bytes): A short paragraph of text
• 1 Megabyte (1,024 kB): A compressed photo or one minute of MP3 audio
• 1 Gigabyte (1,024 MB): About 250 MP3 songs or a short HD video
• 1 Terabyte (1,024 GB): About 250,000 photos or 500 hours of HD video
• 1 Petabyte (1,024 TB): About 1,000 consumer hard drives
• 1 Exabyte (1,024 PB): Roughly 11 million hours of 4K video

Data Transfer Rates vs. Storage

An important distinction exists between data transfer rates and storage capacity:

• Transfer rates use bits per second: kbps, Mbps, Gbps (note lowercase 'b')
• Storage capacity uses bytes: kB, MB, GB, TB (note uppercase 'B')

To convert between them, divide the bit rate by 8 to get the byte rate. For example, a 100 Mbps internet connection can transfer at most 12.5 MB per second (100 / 8 = 12.5).

Tips for Data Storage Conversions

• To convert between adjacent byte units (kB → MB → GB → TB → PB → EB), divide by 1,024 to go up or multiply by 1,024 to go down. The same applies to bit units (kb → Mb → Gb → Tb → Pb → Eb).
• To convert between bits and bytes at the same prefix level, divide bits by 8 to get bytes, or multiply bytes by 8 to get bits. For example: 100 Mb = 12.5 MB.
• When comparing internet speed (in Mbps) with file size (in MB), divide the speed by 8 to estimate download time. A 100 Mbps connection downloads at about 12.5 MB/s, so a 1 GB file takes about 80 seconds.
• Storage manufacturers use decimal (1 GB = 1,000,000,000 bytes) while operating systems use binary (1 GB = 1,073,741,824 bytes). This is why a "500 GB" drive shows as about 465 GB in your OS.
• A nibble is exactly 4 bits (half a byte) and represents one hexadecimal digit. Two nibbles make one byte.
• Memory (RAM) sizes always use binary: 4 GB, 8 GB, 16 GB, 32 GB. These are exact powers of 2 in bytes.
• When estimating storage needs: text files are measured in kB, photos and songs in MB, movies and games in GB, hard drives in TB, and data centers in PB or EB.
