What is the difference between MB and MiB (Megabyte vs Mebibyte)?

A Megabyte (MB) is decimal ($10^6 = 1,000,000$ bytes), while a Mebibyte (MiB) is binary ($2^{20} = 1,048,576$ bytes). Operating systems often label binary mebibytes as 'MB'.

Why does my 1TB hard drive only show 931 GB in Windows?

Hard drive manufacturers sell drives in decimal ($1\text{ TB} = 1,000,000,000,000$ bytes). Windows calculates capacity in binary GiB ($1,000,000,000,000 / 1,024^3 \approx 931.32\text{ GiB}$).

How many bits are in a byte?

There are exactly 8 bits in 1 byte (1 Byte = 8 bits). Internet speeds are measured in bits per second (Mbps), while file sizes are in bytes (MB).

How many gigabytes are in a terabyte?

In decimal SI, $1\text{ TB} = 1,000\text{ GB}$. In binary IEC, $1\text{ TiB} = 1,024\text{ GiB}$.

How many photos or songs fit in 128 GB of storage?

128 GB holds approximately 32,000 standard 4MB JPEG photos or 25,000 high-quality 5MB MP3 audio songs.

What is the difference between decimal (KB/MB) and binary (KiB/MiB) data units?

Decimal storage units use powers of 10 (1 KB = 1,000 bytes), whereas binary IEC units use powers of 2 (1 KiB = 1,024 bytes).

How Many Megabytes (MB) Are in a Gigabyte (GB)?

In binary computing (IEC standard used by RAM and OS file systems), 1 Gigabyte (GiB) = 1,024 Megabytes (MiB) = 1,048,576 Kilobytes = 1,073,741,824 Bytes. In decimal storage (SI standard used by hard drive manufacturers), 1 Gigabyte (GB) = 1,000 Megabytes = 1,000,000,000 Bytes.
