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

## What is a Megabyte?

A Megabyte also known as “MB” is a storage measurement unit whose value is equal to one million bytes. For its part, a byte consists of a set of eight bits. “Megabyte” comes from the Greek “µέγας” which means large. Regarding its conversion value, it is known that one Megabyte is equivalent to 1024 Kilobytes. Megabytes are widely used in the field of computing 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. Thanks to this information, a user can compress the size of a file , increase the size of a disk or adjust the size of a photo as appropriate.

### What is a Gigabyte?

A Gigabyte also known as “GB” is a storage measurement unit whose value is equal to one thousand Megabytes. The word Gigabyte comes from the Greek “γίγας” which refers to a giant. Regarding its conversion value, it is known that one Gigabyte is equivalent to 1024 Megabytes.

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

To be able to convert storage measurement units such as Megabytes to Gigabytes through a formula, it is necessary that you first know the value of each of them and a very simple procedure that will be very useful for you when carrying out said conversion.

### What is the value of a Megabyte?

It is considered that a Megabyte can have two different values depending on the context. In a binary system used by a computer, one MB is made up of 1,048,576 bytes. Instead, in decimal notation, an 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 shown in base 2, that is, by means of a binary system. While the multiples of bytes that we humans use are expressed by 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 by means of the binary system (230) especially in those storage devices such as RAM memories.

### What is the formula to convert Megabytes to Gigabytes

The formula for converting Megabytes to Gigabytes uses the equivalence between units. In this sense, since 1 Gigabyte is equivalent to 1024 Megabytes (1,073,741,824 bytes) we can carry out a simple rule of three through the following condition: if 1 Gigabyte is equivalent to 1024 Megabytes, then “so many” Megabytes equal “X” Gigabytes, where “X” is the result of the operation.

For example, if you want to convert 2500 Megabytes to Gigabytes, you would 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 such as the one offered by the calcuworld website .

### 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 unit byte, continues in Kilobyte, continues with Megabyte, goes to Gigabyte and ends in the largest unit or Terabyte.

In this way, to convert from a small unit to a larger one (from bottom to top) the value must be divided by 1024 and to convert a large unit to a smaller unit (from top to bottom) the value must be multiplied 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 reach the bytes first and then multiply the obtained value by 8.
