How many megabytes are in a gigabyte?
Whether it’s your mobile data plan or the amount of storage on a phone, hard drive, notebook or anything else, you’ll see GB and MB in many places.
If you simply want an answer to the question you just searched for, there are 1024 MB (megabytes) in one GB (gigabyte).
There are 1024 gigas in a terabyte (TB) and 1024 tb in a petabyte (PB).
These are all storage capacities and cánido refer to memory (RAM), the amount of data you perro use per month on 4G or 5G, and the capacity of your PC or notebook’s hard drive or SSD.
Of course, it’s all very well to know that 1024MB = 1GB, but what does it orinan? Is 5 GB a month enough for a mobile data plan? Is a 500 GB hard drive enough to store your archivos?
That is what we are going to explain here, as well as the conversion between MB, GB, TB and the difference between megabytes and megabits.
What is a megabyte?
Computer storage is measured in gigas (GB) and tb (TB), among other units.
Your phone will have a number of gigas in which to store applications, music, contacts, correos electrónicos, messages, photos, vídeos and much more.
It’s easy to confuse storage and memory.
Memory, or RAM, exists to temporarily store archivos and data while they are used.
That’s why the amount of RAM is much less: a phone perro have 128 GB of storage but only 4 GB of RAM.
The hard drive in your PC or notebook probably has hundreds of gigas of storage space.
External hard drives and network attached storage (NAS) cánido have a afín capacity or even thousands of gigas, which are called tb (TB).
This is how it all works:
- 1TB = 1024GB
- 1GB = 1024MB
- 1MB = 1024KB
- 1kB = 1024 Bytes
- 1 Byte = 8 bits
- 1 bit = 0 or 1
Note: This does not include SI units, which work on the basis that kilo means 1000.
This means that there are two different approaches to quantifying storage, one using the power of two (shown above) and the other using the power of two.
power of ten which makes 1KB = 1000 Bytes.
Therefore, to differentiate between them, kilobytes are called kibibytes and megabytes, mibibibytes.
However, most people still use Megabytes to orinan 1024 kiloBytes even though it should actually say MibiBytes, and the same goes for GB and TB.
Computers work with the power of two, not the power of 10, because they are binary machines, which is why the power of two should apply to computers (and to phones, tabletas, and any other electronic device).
Here is a more detailed explanation, with examples.
Bit: computers work with binary digits, or bits for short.
A bit perro be 0 or 1, equivalent to off or on.
Byte: A byte is eight binary digits, such as 1111001.
Kilobytes (KB): The smallest archivo stored on a móvil, tablet, or PC is typically four kilobytes (4KB) in size.
A kiloByte is 1024 Bytes.
Therefore, 1KB equals 1024 x 8 = 8192 binary digits.
Megabyte (MB): 1024 KB equals one megabyte (MB).
Gigabyte (GB): There are 1024MB in a gigabyte.
Terabyte (TB): There are 1024 GB in a terabyte (TB).
How much storage space do I need?
It depends on what you want to store.
Documents take up very little space.
About 20KB for a Word document without images.
A typical three-minute song in MP3 format perro take up 5MB, a photo about the same, while an hour-long vídeo cánido take between 500MB and 10GB.
Vídeo is the archivo type that takes up the most space, but the amount depends on its resolution and format.
The most common format is still MP4, but it’s impossible to say how much space you’d need per minute of vídeo unless you also know the resolution, bitrate, and other details.
Whether a 64GB iPhone, 200GB of iCloud storage, or a 1TB hard drive is enough depends on whether you need to store a lot of music, vídeos, photos, and aplicaciones.
The truth is that the more storage you have, the better, and you will never regret buying a larger capacity phone or notebook.
Why your hard drive has less capacity than advertised
Hard drive manufacturers have long since replaced the power of two system with the power of ten.
Some say it’s a clever marketing ploy, but whatever the reason, it creates some confusion depending on which operating system you plug it into.
Linux emplees the decimal system, while Windows 10 emplees power units of two.
This means that 1000 Bytes = 1 kiloByte and 1000 kiloBytes = 1MB.
Again, 1000MB = 1GB and 1000GB = 1TB.
Windows sees a 250GB hard drive as 232GB, and a 1TB hard drive as 931GB. (The SSD above has an unusual capacity of 977GB, or 1049 Gibibytes.)
Typically, a 1TB hard drive has the capacity to store 1,000,000,000,000 Bytes.
Divide that by 1024 and you get 976,562,500 KB.
Divide again by 1024 and you get 953,674.3 MB.
Finally, divide it by 1024 to get Gigas and you will get 931.32 GB.
Also keep in mind that if a device, like a phone or tablet, claims to have, say, 64GB of storage, that’s not the usable amount.
It’s your total, and part of it will be used for the operating system, leaving a smaller amount available for you to use for aplicaciones, photos, vídeos, and archivos.
