Convert between bits, bytes, kilobytes, megabytes, gigabytes, and terabytes.

Using decimal standard (1 KB = 1000 Bytes)

Digital Storage Converter: KB, MB, GB & TB Explained

In the digital age, understanding storage capacity is essential. Whether you're figuring out how many high-res photos fit on your 64GB smartphone, managing cloud storage, or translating internet speeds (Megabits) to file download sizes (Megabytes), our Digital Storage Converter clarifies these calculations instantly.

Bits vs. Bytes: The Crucial Difference

  • Bit (b): The smallest unit of digital data, representing a binary value of 0 or 1. Internet connection speeds are almost always measured in bits per second (e.g., 100 Mbps).
  • Byte (B): A group of 8 bits. File sizes, hard drive capacities, and RAM are measured in Bytes (e.g., 500 GB Hard Drive).
  • The Rule of 8: To convert bits to Bytes, divide by 8. To convert Bytes to bits, multiply by 8. This is why a 100 Mbps internet connection downloads a file at roughly 12.5 MB/s.

Decimal vs. Binary Prefixes

One of the most confusing aspects of digital storage is the difference between how manufacturers market products and how computers read them.

Decimal (SI) Standard: Used by hard drive manufacturers. 1 Kilobyte (KB) = 1,000 Bytes.
Binary (IEC) Standard: Used by operating systems like Windows. 1 Kibibyte (KiB) = 1,024 Bytes.

Note: This tool uses the Decimal (SI) standard (1 KB = 1000 Bytes) which is the industry standard for labeling storage devices.

Common Storage Capacities

Unit Symbol Approx Value Real-World Example
Kilobyte KB 1,000 Bytes A short text email
Megabyte MB 1,000 KB A high-quality MP3 song
Gigabyte GB 1,000 MB A standard HD movie
Terabyte TB 1,000 GB Modern external hard drives

Frequently Asked Questions (FAQ)

Why does my 1TB drive only show 931GB?

This is due to the Decimal vs. Binary difference. Manufacturers count 1TB as 1,000,000,000,000 bytes, but computers calculate 1TB (or 1 TiB) as 1,099,511,627,776 bytes. The computer sees fewer "binary" GBs in the same amount of space.

How many MB are in a GB?

In the standard decimal system used by this tool, there are 1,000 MB in 1 GB.
