1 MB = 1024 x 1024 Bytes = 1,048,576 Bytes

MB stands for Megabyte. MB( Megabyte ) is a unit that stores digital information in computer and information technology. Originally, MB( Megabyte) was used to describe byte multiples in computer programming. Operating systems refer to MB( Megabyte) as \mathbf{1024}\times \mathbf{1024}\ bytes. But many organizations and storage media like hard drives etc., use a Latin approach to measurement. In the Latin language, 1 Megabyte is 10002 bytes. A megabyte is more significant than a byte. MB( Megabytes) conversion to bytes depends on the unit conversion system. There are two systems of units of transformation we are using, one is SI ( System of Internationale) Units, and the other is B (Binary) system.

In computer and information technology, a byte is one of the smallest units of memory, and in programming, it is one of the basic data measurement units. A byte is a basic unit for the transmission and storage of digital information.

Conversions From Megabyte To Bytes

Megabyte in SI and Decimal (base 10) system

\[\mathbf{1}\text{ }\mathbf{Megabyte}\text{ }=\mathbf{100}{{\mathbf{0}}^{2}}=\text{ }\mathbf{1000}\times \mathbf{1000}\]

\[\mathbf{1}\text{ }\mathbf{Megabyte}\text{ }=\text{ }\mathbf{1000000}\text{ }\mathbf{bytes}\]

Megabyte in Binary (base 2) system

\[\mathbf{1}\text{ }\mathbf{Megabyte}\text{ }={{\mathbf{2}}^{\mathbf{20}}}\mathbf{bytes}\]

\[\mathbf{1}\text{ }\mathbf{Megabyte}\text{ }={{\mathbf{2}}^{\mathbf{10}}}\times {{\mathbf{2}}^{\mathbf{10}}}\mathbf{bytes}\]

\[\mathbf{1}\text{ }\mathbf{Megabyte}\text{ }=\text{ }\mathbf{1024}\times \mathbf{1024}\text{ }=\text{ }\mathbf{1},\mathbf{048},\mathbf{576}\text{ }\mathbf{bytes}.\]

Examples

Q1: Convert 7 MB to bytes using the binary system.

Ans: We know \[\mathbf{1}\text{ }\mathbf{MB}\text{ }=\text{ }\mathbf{1},\mathbf{048},\mathbf{576}\text{ }\mathbf{bytes}\]

Then, \[\mathbf{7}\text{ }\mathbf{MB}\text{ }=\mathbf{7}\: X\: \mathbf{1048},\mathbf{576}=\mathbf{7},\mathbf{340},\mathbf{032bytes}.\]]

Hence, in \: the\: binary\: system, \[\mathbf{7}\text{ }\mathbf{MB}\text{ }=\text{ }\mathbf{7},\mathbf{340},\mathbf{032}\text{ }\mathbf{bytes}.\]

Q2: Convert 7 MB to bytes using SI units.

Ans: We know \[\mathbf{1}\text{ }\mathbf{MB}\text{ }=\text{ }\mathbf{1},\mathbf{000},\mathbf{000}\text{ }\mathbf{bytes}\]

Then, \[\mathbf{7}\text{ }\mathbf{MB}\text{ }=\mathbf{7}\: X\: \mathbf{1000},\mathbf{000}=\mathbf{7},\mathbf{000},\mathbf{000bytes}.\]

Hence, in \: SI\: Units, \[\mathbf{7}\text{ }\mathbf{MB}\text{ }=\text{ }\mathbf{7},\mathbf{000},\mathbf{000}\text{ }\mathbf{bytes}.\]

Q3: Convert 2 Megabytes to bytes using the decimal system.

Ans: We know \[\mathbf{1}\text{ }\mathbf{MB}\text{ }=\text{ }\mathbf{1},\mathbf{000},\mathbf{000}\text{ }\mathbf{bytes}\]

Then, \[\mathbf{2}\text{ }\mathbf{MB}\text{ }=\mathbf{2\: X\: 1},\mathbf{000},\mathbf{000}=\mathbf{2},\mathbf{000},\mathbf{000bytes}.\]

Hence, in \; SI \: Units, \[\mathbf{2}\text{ }\mathbf{MB}\text{ }=\text{ }\mathbf{2},\mathbf{000},\mathbf{000}\text{ }\mathbf{bytes}.\]

Q4: Compare the conversion of 4 Megabytes to bytes in both base 2 and base 10 systems.

Ans: In the base 2 system, we know

\[\mathbf{1}\text{ }\mathbf{MB}\text{ }=\text{ }\mathbf{1},\mathbf{048},\mathbf{576}\text{ }\mathbf{bytes}\]

Then, \[\mathbf{4}\text{ }\mathbf{MB}\text{ }=\mathbf{4\: X\: 1},\mathbf{048},\mathbf{576}=\mathbf{4},\mathbf{194},\mathbf{304bytes}.\]

In\: the \: base\: 10\; system, we\; know

\[\mathbf{1}\text{ }\mathbf{MB}\text{ }=\text{ }\mathbf{1},\mathbf{000},\mathbf{000}\text{ }\mathbf{bytes}\]

Then, \[\mathbf{4}\text{ }\mathbf{MB}\text{ }=\mathbf{4\; X\; 1},\mathbf{000},\mathbf{000}=\mathbf{4},\mathbf{000},\mathbf{000bytes}.\]

Thus, \[\mathbf{4}\text{ }\mathbf{MB}\text{ }\left( \text{ }\mathbf{in}\text{ }\mathbf{the}\text{ }\mathbf{base}\text{ }\mathbf{2}\text{ }\mathbf{system} \right)\text{ }>\text{ }\mathbf{4}\text{ }\mathbf{MB}\text{ }\left( \text{ }\mathbf{in}\text{ }\mathbf{the}\text{ }\mathbf{base}\text{ }\mathbf{10}\text{ }\mathbf{system} \right).\]
