What is a Megabyte?

One Megabyte also known as "MB" is a unit of memory measure il whose value is one million bytes. For its part, a byte consists of a set of eight bits. "Megabyte" comes from the Greek "µέγας" which means big. As for its conversion value, it is known that one Megabyte equals 1024 Kilobytes.

Megabytes are widely used in computer science to define the size of an image file, music in various formats, the storage capacity of a compact disc (CD), or the data storage size of a hard drive. With this information, a user can compress the size of a file, increase the size of a disc, or adjust the size of a photo as appropriate.



What is a Gigabyte?

A Gigabyte also known as "GB" is a unit of memory which is equal to one thousand Megabytes. The word Gigabyte comes from the Greek “γίγας” which refers to a giant. As for its conversion value, it is known that One gigabyte is equal to 1024 megabytes..

How to convert Megabytes to Gigabytes through the step by step formula

In order to convert memory units like Megabyte to Gigabyte through a formula, you need to know first the value of each of them and a very simple procedure that will be very useful to you when you do such a conversion.

What is the value of a Megabyte?

It is believed that a Megabyte can take on two different values ​​a depending on the context. In a binary system used by a computer, one MB consists of 1.048.576 bytes. Instead, in decimal notation, a MB is made up of 1.000.000 bytes or 16.



The reason for this variation is due to the fact that the multiples of bytes required in a computer are reported in base 2, that is, through a binary system. While the multiples of bytes that we humans use are expressed in base 10, that is the decimal system.

What is the value of a Gigabyte?

A Gigabyte has a value of 1.000.000.000 bytes according to the decimal system. However, this unit of measurement can also be expressed in powers of two or through the binary system (230) especially in those storage devices such as RAM memories.

What is the formula to convert Megabyte to Gigabyte?

The formula for converting Megabytes to Gigabytes uses equivalence between units. In this sense, since 1 Gigabyte equals 1024 Mega (1.073.741.824 bytes) we can perform a simple rule of three through the following condition: if 1 Gigabyte equals 1024 Mega, then "many" Megabytes equals "X" Gigabytes, where "X" is the result of the operation.

For example, if you want to convert 2500 Megabytes to Gigabytes, divide 2500 by 1024. So the result you get is 2,44 Gigabytes. If you prefer to perform the calculation automatically, you can choose to use a byte calculator like the one offered by the calcuworld site.


Trick to apply the formula quickly

A simple trick to apply the conversion formula is to know the "Ladder rule" which starts in the small byte unit, continues in Kilobyte, continues with Megabyte, goes in Gigabyte, and ends in the largest unit or Terabyte.

This way, to convert from a small unit to a larger one (bottom to top), divide the value by 1024 and to convert a large unit to a smaller unit (top to bottom) , multiply the value by 1024.


The exception to the rule

There is an exception to the rule when the conversion formula is applied. This occurs between the two smallest storage units: the byte and the bits. Since one byte equals 8 bits, then the bit conversion must first reach the bytes and then multiply the resulting value by 8.
