How many Megabytes (MB) are in a Gigabyte (GB)?

In decimal SI notation, `1 GB = 1,000 MB`. In binary IEC notation, `1 GiB = 1,024 MiB`.

What is the difference between a Bit (b) and a Byte (B)?

A bit (lowercase 'b') is the fundamental binary unit (0 or 1). A byte (uppercase 'B') consists of 8 bits (`1 Byte = 8 bits`). Network speeds are usually measured in bits (Mbps), while file sizes are measured in bytes (MB).

Why does my 500GB hard drive only show 465GB on Windows?

Drive manufacturers define 500 GB as `500,000,000,000 bytes`. Windows calculates capacity using binary: `500,000,000,000 / (1024³)` equals approximately `465.66 GiB`.

How many bytes are in a Terabyte (TB)?

One Terabyte (TB) equals 1,000 Gigabytes, 1,000,000 Megabytes, or `1,000,000,000,000 bytes` (10¹² bytes).

What is a Petabyte (PB)?

A Petabyte is 1,000 Terabytes (or 1,024 TiB in binary), equivalent to `1,000,000,000,000,000 bytes` (10¹⁵ bytes), commonly used in cloud data centers.

What Is the Difference Between Gigabytes (GB) and Gibibytes (GiB)?

A Gigabyte (GB) uses standard decimal SI notation where 1 GB = 1,000 MB = 1,000,000,000 bytes (10⁹). A Gibibyte (GiB) uses binary IEC notation where 1 GiB = 1,024 MiB = 1,073,741,824 bytes (2³⁰). Operating systems like Windows report storage in binary (GiB) while hard drive manufacturers market capacity in decimal (GB), which is why a 1 TB drive shows ~931 GiB of usable space.

Mathematical Formula & Equations

Converts digital data size across Bits, Bytes, Kilobytes, Megabytes, Gigabytes, Terabytes, and Petabytes in binary (1024) and decimal (1000) base.

\[ 1 \text{ Byte} = 8 \text{ bits}, \quad 1 \text{ KB} = 1,024 \text{ Bytes}, \quad 1 \text{ MB} = 1,024 \text{ KB}, \quad 1 \text{ GB} = 1,024 \text{ MB}, \quad 1 \text{ TB} = 1,024 \text{ GB} \]

Calculation Example

500 Gigabytes (GB) = 512,000 Megabytes (MB) = 0.488 Terabytes (TB).
