Megabytes

Megabyte (MB) is a unit of transferred or stored digital information, which is extensively used in information and computer technology. In SI, one megabyte is equal to 1,000,000 bytes. At the same time, practically 1 megabyte is used as 2²⁰ B, which means 1,048,576 bytes. Nowadays, the amount of information measured by megabytes is used for representing the size of a typical MP3 file, the size of a JPEG image, and so on.

Megabyte in SI and base 10 (decimal)
1 Megabyte = 1000² bytes
1 Megabyte = 1,000,000 bytes
Megabyte in base 2 (binary)
1 Megabyte = 2²⁰ bytes
1 Megabyte = 1024² bytes
1 Megabyte = 1,048,576 bytes

Gigabytes

Gigabyte (GB) is one of the most commonly used units of digital information which is equal to 1,000,000,000 bytes. However, in computer operating science, the value of 1 GB is considered to be equal to 2³⁰ or 1024³ bytes which is equal to 1,073,741,824 bytes. GB is often used for indicating a size of memory or specifying a size of a movie, computer RAM, and so on. The maximum amount of information stored in a single layer DVD is usually close to 4.8 GB, and the maximum amount of information that can be stored in a single layer Blu-ray disc is equal to 25 GB.

How to Calculate Megabytes to Gigabytes

Megabyte in SI
1 Megabyte = 1000² bytes
We know that 1GB = 1000³ bytes, so
1 byte = 1000^-3 GB
putting 1 byte in megabyte equation;
1 Megabyte = 1000² * 1000^-3 GB
1 Megabyte = 1000^-1 Gigabytes
1 Megabyte = 0.001 Gigabytes

MB to GB in Base 2

Megabyte in base 2
1 Megabyte = 2²⁰ bytes
1 Megabyte = 1024² bytes
1 byte = 1024^-3 GB
1 Megabyte = 1024² * 1024^-3 GB
1 Megabyte = 1024^-1 Gigabytes
1 Megabyte = 2^-10 Gigabytes
1 Megabyte = 0.0009765625 Gigabytes
