MB to KB Conversion

Convert megabytes to kilobytes:

Example: 5 MB = 5 × 1024 = 5,120 KB

Example: 2 MB = 2 × 1024 = 2,048 KB

KB to MB Conversion

Convert kilobytes to megabytes:

Example: 5120 KB = 5120 ÷ 1024 = 5 MB

Example: 1024 KB = 1024 ÷ 1024 = 1 MB

GB to MB Conversion

Convert gigabytes to megabytes:

Example: 2 GB = 2 × 1024 = 2,048 MB

Example: 1 TB = 1 × 1024 × 1024 = 1,048,576 MB

MB to GB Conversion

Convert megabytes to gigabytes:

Example: 2048 MB = 2048 ÷ 1024 = 2 GB

Example: 500 MB = 500 ÷ 1024 = 0.488 GB

Byte (B)

The fundamental unit of digital information. 1 byte = 8 bits. Can store a single character (like 'A' or '5').

Kilobyte (KB)

1 KB = 1,024 bytes. Typical size for small text files, icons, or simple images. Example: A plain text email is about 2-10 KB.

Megabyte (MB)

1 MB = 1,024 KB = 1,048,576 bytes. Used for photos, MP3 songs, small videos. Example: A high-quality photo is 2-5 MB, a 3-minute MP3 song is about 3-4 MB.

Gigabyte (GB)

1 GB = 1,024 MB. Standard for RAM, USB drives, and SD cards. Example: A 2-hour HD movie is about 3-5 GB, smartphone storage is typically 64-512 GB.

Terabyte (TB)

1 TB = 1,024 GB = 1,048,576 MB. Used for hard drives and data centers. Example: Modern hard drives are 1-16 TB, can store about 200,000 high-quality photos.

Petabyte (PB)

1 PB = 1,024 TB. Enterprise-level storage for massive databases, cloud services, and data centers. Example: Large companies like Google process petabytes of data daily.

How many KB in 1 MB?

1 MB (megabyte) equals 1024 KB (kilobytes) in binary system used by computers. In decimal system, 1 MB = 1000 KB. Most operating systems and file managers use the binary system (1024).

How do you convert MB to KB?

To convert megabytes to kilobytes, multiply the MB value by 1024. Formula: KB = MB × 1024. For example, 5 MB = 5 × 1024 = 5120 KB. This uses the binary system standard in computing.

How many MB in 1 GB?

1 GB (gigabyte) equals 1024 MB (megabytes) in binary system. In decimal, 1 GB = 1000 MB. Computer memory and storage typically use binary (1024), while hard drive manufacturers often use decimal (1000).

What is the difference between MB and Mb?

MB (uppercase B) stands for megabyte (data storage), while Mb (lowercase b) stands for megabit (data transfer rate). 1 byte = 8 bits, so 1 MB = 8 Mb. Internet speeds use megabits per second (Mbps), while file sizes use megabytes (MB).

Why is 1 KB equal to 1024 bytes and not 1000?

Computers use binary (base-2) system. 1024 = 2^10, which is the nearest power of 2 to 1000. This binary convention (1024) is called a kibibyte (KiB), while 1000 bytes is technically a kilobyte (KB) in decimal. However, KB commonly refers to 1024 bytes in computing.

How do you convert GB to MB?

To convert gigabytes to megabytes, multiply the GB value by 1024. Formula: MB = GB × 1024. For example, 2 GB = 2 × 1024 = 2048 MB. For decimal conversion, multiply by 1000 instead.

How many bytes in 1 MB?

1 MB = 1,048,576 bytes (binary system). This is calculated as 1024 × 1024 = 1,048,576. In decimal system, 1 MB = 1,000,000 bytes.

Why do hard drives show less space than advertised?

Hard drive manufacturers use decimal (1000) system, while operating systems use binary (1024). A "1 TB" drive has 1,000,000,000,000 bytes, but your OS calculates 1,000,000,000,000 ÷ 1024³ ≈ 931 GB. This explains the "missing" storage.

1. Choose the Right Storage Device

USB drives: 16-256 GB for portable files. External HDD: 1-16 TB for backups. SSD: 256 GB-2 TB for speed. Cloud storage: Unlimited for accessibility.

2. Compress Large Files

Use ZIP or RAR compression to reduce file sizes by 20-90%. Videos and images can be compressed with specialized tools to save storage space and transfer time.

3. Understand File Transfer Times

USB 2.0: ~35 MB/s. USB 3.0: ~100-200 MB/s. USB 3.1: ~500-1000 MB/s. Wi-Fi: 5-50 MB/s. Ethernet: 12-125 MB/s.

4. Monitor Storage Space

Keep at least 10-15% free space on drives for optimal performance. Full drives slow down significantly and can corrupt data.

5. Calculate Before Purchasing

Use this converter to determine storage needs. Photos (5 MB each): 200 photos = 1 GB. Movies (4 GB each): 250 movies = 1 TB.
