Common mistakes in data storage conversion

  • Drive makers count in decimal: 1 TB = 1,000 GB = 10¹² bytes. Operating systems often display binary units (powers of 1,024), so the same drive shows up as about 931 'GB', really gibibytes (GiB). The 'missing' 69 gigabytes are just two counting systems, nothing is lost.
  • A byte is 8 bits, and the abbreviations differ only in letter case: lowercase b for bits (Mbit), uppercase B for bytes (MB). Broadband is sold in megabits per second while files are measured in megabytes. Mixing them up makes every figure wrong by a factor of eight.
  • In SI, 1 kB = 1,000 bytes, while 1,024 bytes is a kibibyte (KiB). Historically 'kB' has meant both, so different tools report different sizes for the same file. RAM is always counted in binary; storage media usually in decimal.

Quick conversion quiz

Score: 0

207 gigabyte equals 1.04e+5 megabyte.

Correct answer: 207 gigabyte = 2.07e+5 megabyte.

25 kilobyte equals 4.0e+4 bit.

Correct answer: 25 kilobyte = 2.0e+5 bit.

14.4 kilobyte equals 1.44e+4 byte.

Correct answer: 14.4 kilobyte = 1.44e+4 byte.

50 byte equals 5.0e-5 megabyte.

Correct answer: 50 byte = 5.0e-5 megabyte.

Frequently asked questions

Why does my 1 TB drive show less than 1 TB on my computer?

Drive makers use decimal units (1 TB = 1,000,000,000,000 bytes), but many computers show binary units (TiB). 1 TB is about 0.909 TiB, so it appears smaller.

What is the difference between GB and GiB?

GB is decimal: 1 GB = 1,000,000,000 bytes. GiB is binary: 1 GiB = 1,073,741,824 bytes. Some systems display GiB but label it as GB.

How many GB are in 1 TB?

In decimal units, 1 TB equals 1000 GB. (Binary units are different: 1 TiB equals 1024 GiB.)

How many bytes are in a kilobyte?

kB is decimal: 1 kB = 1000 bytes. KiB is binary: 1 KiB = 1024 bytes.

What is the difference between MB and MiB?

MB is decimal: 1 MB = 1,000,000 bytes. MiB is binary: 1 MiB = 1,048,576 bytes. The difference is about 4.9%.

How many bits are in a byte?

There are 8 bits in one byte. That’s why file sizes (bytes) and internet speeds (bits) use different numbers.

How do I use the data storage converter on konvertera.nu?

Enter the size (for example 500 GB), select whether you mean decimal (GB) or binary (GiB) units if needed, then convert to your target unit.
