Frequently Asked Questions

How do I convert KB to MB?

To convert kilobytes (KB) to megabytes (MB), divide by 1,000. For example, 5,000 KB = 5 MB. If using binary units, 1,024 KB = 1 MiB (mebibyte). This converter uses decimal (SI) units where 1 KB = 1,000 bytes and 1 MB = 1,000,000 bytes.

How do I convert MB to GB?

To convert megabytes (MB) to gigabytes (GB), divide by 1,000. For example, 2,000 MB = 2 GB. In binary: 1,024 MiB = 1 GiB. Most file systems and operating systems display file sizes using MB and GB, but they may actually mean MiB and GiB.

How do I convert GB to TB?

To convert gigabytes (GB) to terabytes (TB), divide by 1,000. For example, 500 GB = 0.5 TB, 2,000 GB = 2 TB. In binary: 1,024 GiB = 1 TiB. Hard drives are typically advertised in decimal TB.

How many bytes are in a megabyte?

In decimal (SI), 1 megabyte (MB) = 1,000,000 bytes (1 million bytes). In binary, 1 mebibyte (MiB) = 1,048,576 bytes (2^20 bytes). The confusion between these two definitions is a common source of storage capacity discrepancies.

How many bytes are in a gigabyte?

In decimal (SI), 1 gigabyte (GB) = 1,000,000,000 bytes (1 billion bytes). In binary, 1 gibibyte (GiB) = 1,073,741,824 bytes (2^30 bytes). This 7.37% difference is why a 500 GB hard drive shows as about 465 GB in Windows.

How many bytes are in a terabyte?

In decimal (SI), 1 terabyte (TB) = 1,000,000,000,000 bytes (1 trillion bytes). In binary, 1 tebibyte (TiB) = 1,099,511,627,776 bytes (2^40 bytes). A 1 TB drive has about 931 GiB of actual capacity.

How do I convert bytes to KB?

To convert bytes to kilobytes (KB), divide the number of bytes by 1,000. For example, 50,000 bytes / 1,000 = 50 KB. In binary: divide by 1,024 to get KiB. This converter uses decimal (SI) units by default.

How do I convert bytes to MB?

To convert bytes to megabytes (MB), divide the number of bytes by 1,000,000. For example, 5,000,000 bytes / 1,000,000 = 5 MB. For binary: divide by 1,048,576 to get MiB. This auto-converter shows all unit conversions simultaneously.

How many MB is 1 GB?

1 GB = 1,000 MB (decimal) or 1,024 MiB (binary). This means a 1 GB file contains 1,000 MB of data in decimal terms, but the operating system may display it as approximately 976.56 MiB (1,000 MB / 1.024).

How many GB is 1 TB?

1 TB = 1,000 GB (decimal) or 1,024 GiB (binary). A 1 TB hard drive has 1,000,000,000,000 bytes of storage, which the operating system reports as approximately 931 GB or 931 GiB.

How many KB is 1 MB?

1 MB = 1,000 KB (decimal) or 1,024 KiB (binary). This means a 1 MB file contains 1,000 KB of data in decimal terms. In binary, 1 MiB = 1,024 KiB.

How many MB is 1 GB in binary?

In binary, 1 GiB (gibibyte) = 1,024 MiB (mebibytes). This is the system used by most operating systems including Windows, macOS, and Linux when reporting file sizes and storage capacity.

What is the difference between a byte and a bit?

A byte (B) is 8 bits (b). Bits are used to measure data transfer speeds (Mbps, Gbps), while bytes are used to measure file sizes (MB, GB). To convert: multiply bytes by 8 to get bits, or divide bits by 8 to get bytes.

Why does my 256 GB phone show less available storage?

A 256 GB phone has 256,000,000,000 bytes of storage (using decimal). The operating system reports in binary, showing about 238 GiB. Additionally, the OS and pre-installed apps take up significant space, further reducing available storage.

How many photos can I store on a 64 GB phone?

At 3 MB per photo (typical smartphone camera), a 64 GB phone can store approximately 21,000 photos (64,000 MB / 3 MB). Actual capacity is less due to OS overhead and the decimal vs binary difference.

How many songs can I store on a 128 GB device?

At 5 MB per song (typical MP3 at 256 Kbps), a 128 GB device can store approximately 25,600 songs (128,000 MB / 5 MB). Using lossless audio (30 MB per song), it can store about 4,200 songs.

How many GB is a typical movie?

A 2-hour HD movie (1080p) is typically 4-8 GB. A 4K movie is typically 15-30 GB. A Blu-ray movie can be 25-50 GB. Streaming quality movies are smaller due to compression (2-4 GB for 1080p).

How many MB is a typical MP3 song?

A typical MP3 song is 3-6 MB at 256 Kbps quality, or 7-10 MB at 320 Kbps. A 3-minute song at 128 Kbps is about 2.8 MB. Lossless formats (FLAC, ALAC) are 20-40 MB per song.

How many KB is a typical email?

A plain text email without attachments is typically 2-10 KB. An email with a few embedded images can be 100-500 KB. With attachments, emails can range from a few MB to 25 MB (common attachment size limit).

How many GB is a typical video game?

Modern video games range from 20-150 GB or more. AAA titles like Call of Duty can exceed 150 GB with all updates. Indie games are typically 1-10 GB. Mobile games are usually 100 MB to 2 GB.

What is the largest file size FAT32 supports?

FAT32 has a maximum file size limit of 4,294,967,295 bytes (4 GB - 1 byte). This is why large video files or backups must use exFAT or NTFS file systems. exFAT supports files up to 16 exabytes.

How many MB is 1 GB of RAM?

1 GB of RAM = 1,024 MB (always binary in computer memory). RAM is measured in binary because memory addresses are binary (2^30 = 1,073,741,824 bytes = 1 GiB). Unlike storage, RAM capacity is never advertised in decimal.

How many bytes are in a word?

A "word" in computing is the natural data size of a processor. For modern 64-bit processors, 1 word = 8 bytes (64 bits). For 32-bit processors, 1 word = 4 bytes (32 bits). For 16-bit processors, 1 word = 2 bytes (16 bits).

How do I calculate file size from resolution?

Image file size = width x height x bits-per-pixel / 8 (in bytes). For example, a 1920x1080 image at 24 bits per pixel: 1920 x 1080 x 24 / 8 = 6,220,800 bytes = 6.22 MB (uncompressed BMP). JPEG compression reduces this significantly.

How many megabytes per second is 100 Mbps?

100 Mbps (megabits per second) = 12.5 MB/s (megabytes per second). Divide by 8 to convert. This is why a 100 Mbps internet connection can download at a maximum theoretical speed of 12.5 MB/s.

How much is 1 TB of storage in GB?

1 TB = 1,000 GB (decimal) or 1,024 GiB (binary). A 1 TB drive provides 1,000,000,000,000 bytes of raw storage, which the operating system typically displays as approximately 931 GB.

How many 5 MB files fit in 1 GB?

In decimal: 1 GB / 5 MB = 200 files. In binary: 1 GiB / 5 MiB = about 204 files. The actual number depends on the file system overhead and whether you use decimal or binary units.

How do I determine which unit to use?

File sizes in modern operating systems are typically displayed in binary-based units (KB = 1024 bytes, MB = 1,048,576 bytes, etc.), though they are labeled with SI symbols. Storage devices use decimal units. Data transfer rates always use decimal (Mbps, Gbps).

How many GB is the human genome?

The complete human genome (3.2 billion base pairs) requires about 3.2 GB of storage in uncompressed FASTQ format. Compressed with CRAM or BAM formats, it takes about 0.7-1.2 GB. This demonstrates how much data can be compressed.

What is the difference between MB/s and Mb/s?

MB/s (megabytes per second) = 8 x Mb/s (megabits per second). Capitalization matters: MB = megabyte (8 million bits), Mb = megabit (1 million bits). Always check the letter case when reading speeds.
