How Many Megabytes in a Gigabyte?


Do you know how many megabytes in a gigabyte? In this article, we will discuss everything about megabytes and gigabytes.

We have often encountered words like bytes, kilobytes, megabytes, gigabytes, and so on. But what exactly are they?

Just like us, computers also store Data in some form. We have memories, and computers have RAM and ROM.

RAM (Random Access Memory) is a type of computer memory that can be read and changed at the current time.

ROM (Read Only Memory) is a type of Computer memory that allows the user to read data at any time.

It is a permanent or semi-permanent type of memory. Where RAM is a volatile form of memory, ROM is a non-volatile form of memory. Data in ROM is stored permanently like that in hard discs etc.

This article will cover everything and you will get the answer to the question of how many MB in 1 GB.

What is a Bit?

Every computer stores data in the form of 0s and 1s. A single “0” or “1” is called a bit.

What is a byte?

A byte is an amalgamation of 8 bits in any order. These bits can start with either “0” or “1” and there is no fixed pattern for this.

What is a kilobyte?

A kilobyte is a bigger unit than a byte and is a combination of 1024 bytes, according to a binary system. While according to the decimal system, a kilo word refers to a unit that is 103, so a kilobyte comprises 1000 bytes.

What is a Megabyte?

It is an even bigger storage unit than a kilobyte. One megabyte or MB is made up of 1024 kilobytes (KB) according to the binary system, while according to the decimal system, a megabyte consists of 1000 or 103 KB or kilobytes or 106 bytes.

Megabyte is the most common storage unit in computers, laptops, mobile phones, etc.

However, today even bigger units are used for storage capacity. A high-resolution JPEG image file or other forms of media use MB as the storage unit.

If we want to calculate MB in bytes, we can multiply the number by 1024×1024= 1,048,576.

So you now know about the megabyte, next we will learn about gigabytes and then how many MB in a GB.

What is Gigabyte?

A gigabyte is an even bigger storage unit than a megabyte. One Megabyte consists of 1024 Megabytes roughly. It has been in use since the mid-1980s and is equal to 1 million bytes.

Presented in 1980, the first gigabyte-limit hard drive was the IBM 3380 which bundled two 1.26GB hard plate gatherings in a fridge-measured cupboard.

The cost of such hard drives went from $81,000 to $142,000, contingent upon the arrangement.

Today, many devices use this as a storage unit for transferring files. Different devices come with varying storage capacities.

It is a very common measuring unit for hard disks and other storage devices. Let’s get the answer to the question of how many MB in a gigabyte.

How Many Megabytes in A Gigabyte?

A gigabyte is a much bigger storage unit than a megabyte. Nowadays, gigabyte has become a more common word than any other storage unit.

Be it a mobile phone or a pen drive, everyone out there is talking in terms of GB. Even our data plan also comes in gigabytes.

However, now with the given data, you can easily find out how many megabytes are in a Gigabyte.

1 Gigabyte consists of 1024 megabytes according to the binary system, while according to the decimal system, a gigabyte consists of 1000 megabytes or 106 KB or 109 bytes.

Since there are two ways to convert MB into GB, to ease your confusion and to answer how many Megabytes are in a Gigabyte, we use the binary system of conversion on a standard basis.

Megabytes VS. Gigabytes

As confusing as it may sound, megabytes and gigabytes are two different terms.

You are just required to remember the figures correctly to figure out the bigger unit.

However, to make it easier for you, a Gigabyte is a bigger unit than a Megabyte (here you can remember the movie 3idiots if you are a movie fan).

But, if you are a geek and want to learn about the two units through figures, here is the table for you.

Here you will find all the major differences​ between the two units along with their equal value in terms of bytes KB or, bits. Using this, you can easily infer how many Megabytes are in a Gigabyte.

Megabyte (MB) Gigabyte (GB)
106 bytes (base 10) 109 bytes (base 10)
10002 bytes 10003 bytes
1,000,000 bytes 1,000,000,000 bytes
1,048,576 bytes 1,073,741,824 bytes
1,000,000 × 8 bits 1,000,000,000 × 8 bits
8,000,000 bits 8,000,000,000 bits
Smaller Unit Bigger Unit

MB to GB

Since you have gotten to know about the statistics, it has become easier for you to remember the bigger unit.

However, sometimes, some storage devices are labeled in megabytes and that’s where the real confusion arises.

However, with this really easy MB to GB conversion table, converting MB into GB won’t be a tough task! With the following information, you can easily know how many Megabytes​ in a Gigabyte.

Before you use the data from the below table, it is important to keep in mind that there are two ways to convert GB into MB-

  • First based on the decimal system, where 1 Gigabyte is equal to 1000 megabytes.
  • Second, it is based on a binary system, where 1 Gigabyte is equal to 1024 megabytes.

Generally, the second method is more commonly employed for conversion.

Megabytes to Gigabytes Conversion Table

Megabyte (MB) Gigabyte (GB)
0.01MB 9.765625E-6GB
1 MB 0.0009765625GB
10 MB 0.0048828125GB
100 MB 0.09765625 GB
1000 MB 0.9765625 GB
