What is the difference between a megabyte and a gigabyte?

A megabyte and a gigabyte are both units of digital information. A megabyte is smaller, typically defined as 1,000,000 bytes in decimal terms or 1,048,576 bytes in binary contexts, while a gigabyte is larger, generally equal to 1,000,000,000 bytes in decimal or around 1,073,741,824 bytes in binary interpretations.

Why are there two different values for megabyte and gigabyte?

One value corresponds to the decimal system used in marketing and storage device specifications (powers of 10), and the other to the binary system often used in operating systems and some software (powers of 2), leading to different quantities represented by MB and GB.

How is the conversion from megabytes to gigabytes calculated?

The conversion is done by multiplying the number of megabytes by 0.0009765625 to express the equivalent amount in gigabytes according to the decimal standard.

Key Terminology

Megabyte (MB): A unit of digital information measuring data quantity; defined as 1,000,000 bytes in decimal terms or 1,048,576 bytes in binary contexts.
Gigabyte (GB): A digital information unit used to describe storage capacity; usually 1,000,000,000 bytes in decimal or sometimes referring to 1,073,741,824 bytes in binary, which is more accurately called a gibibyte.
Binary Units (IEC): Standard units based on powers of 2, such as mebibyte (MiB) and gibibyte (GiB), used to precisely indicate binary multiples.
