Megabytes and gigabytes are both considered as storage measurement units. A gigabyte shows more capacity than a megabyte. How many megabytes in a gigabyte, then? This is defined by the system used to measure storage and there are two methods for converting MB to GB.
This explains why there can be a difference between the storage capacity advertised for a drive and the amount shown on your computer.
What is Megabyte?
What is Megabyte?
The megabyte is a unit to measure data storage. In other words, we can say that a unit we prefer to evaluate digital data with a value equal to a million bytes is known as a megabyte.
The byte is the main measuring unit for online data, but further definitions were needed to define the larger volumes of data; so, the megabyte was introduced.
What is Gigabyte?
A gigabyte is a particular unit of data that’s equal to around 1 billion bytes of data. The term gigabyte is generally used to determine the amount of stored data or the capacity of a storage device.
In respect of smaller units, a gigabyte is equal to 1,024 megabytes (MB). If you split a gigabyte into smaller units, you will have approximately 1,024 megabytes. However, a gigabyte represents 0.001 terabytes (TB). If you want to represent gigabyte in larger units, it would be approximately 0.001 terabytes.
How Many Megabytes in a Gigabyte?
There are 1,024 MB in 1 GB when making use of the binary approach. There’s also a second method to measure storage. For now, here’s a guide on converting binary prefixes:
- 1TB = 1,024GB
- 1GB = 1,024MB
- 1MB = 1,024KB
- 1KB = 1,024 Bytes
You’ll discover that your computer storage is most possibly measured in hundreds of gigabytes. SSD (solid state drives) and hard disc drives would possibly be measured in terabytes.
Your phone storage is also measured in gigabytes to store all of your photos, apps, and messages. You’ll observe that iPhones, for example, start at 64 GB.
Before moving ahead, let’s clarify something in case you’re puzzled about the 4 GB listed in your device’s features. Storage and memory (RAM) are two things that can be measured in gigabytes.
Storage is the place for long-term data, like files downloaded to use in the future. On the contrary, memory is only there to store short-term data while the file is being used.
What Are the Two Methods for Measuring Storage?
What Are the Two Methods for Measuring Storage?
There are two methods for demonstrating the appropriate value of a measurement unit. You can evaluate this using the International System of Units (SI) or the binary method, which is commonly used in electronic devices.
They represent two different measurements, where the binary method and the SI method differ by approximately 4.86%.
Converting Using SI
Following the SI (International System of Units), the prefix “Mega” multiplies by 10 or represents a million units. In SI, this signifies it uses the decimal system, based on powers of 10.
In this case, 1 Kilobyte equals 1,000 bytes, which makes 1 gigabyte equal 1,000 megabytes.
Converting Using Binary System
This method is commonly used with binary devices like computers, phones, and tablets. The binary system operates on base 2. In this system, the prefix ‘mega’ equals 1,048,576 bits, so one gigabyte is equivalent to 1,024 megabytes.
Let’s have a look at the representation to obtain a good understanding of how the binary system works:
21 = 2
22 = 4
23 = 8
24 = 16
In binary, each additional digit increases the number’s value by a power of two. For instance, 2 raised to the power of 10 equals 1,024.
This is the reason your hard drive reads at a reduced capacity than what you purchased. Suppose you purchased a 250GB external hard drive and your computer shows only 232 GB of free space for use.
Now, why does this happen? Technologically, the drive has a capacity of 250,000,000,000 bytes. To demonstrate the precise amount of storage space available, work backward through the units of measurement.
Begin by converting bytes to kilobytes, then kilobytes to megabytes, and megabytes to gigabytes. Multiply the whole storage capacity by 1,024 three times to obtain 232 GB.
As the capacity of the disk increases, the difference increases between the advertised size and what the computer displays.
Final Words
How many megabytes in a gigabyte? Following the common terminology there are 1,024 MB in 1GB. We hope now you have a basic understanding of how storage is measured and that you can calculate the capacity of your device easily.
