In a digitized society during which info is so vital, one of many fundamental rules is to know among the fundamental ideas that we transfer about. For this motive, absolutely you’ve gotten heard many occasions about **megabytes, gigabytes, teras and different units of measure**, and you might have considered trying to know what they’re and the way to convert from one to the opposite in order not to confuse them. In addition, we should keep in mind that these phrases cannot solely refer to storage units, but additionally to web velocity.

## What is bit and byte?

The **bit** It is the fundamental unit of data in computing. It consists of a binary language digit that expresses a price of Zero or 1. It is used to symbolize the contraposition between two values which are open and closed, on and off, false and true). This is the minimal unit of data in computing. Although one bit can symbolize two particular values, infinite mixtures may be made. Another related measure is the **byte**, not to be confused with the primary. The latter may be quantized as Eight bits.

In computing and telecommunications, because the construction of computer systems is predicated on binary numbers, bytes are counted in powers of two. Hence, a kilobyte equals 1024 bytes and never 1000, since 1024 is the results of 2 raised to 10.

We are going to present the equivalences between one and the opposite units of measurement primarily based on these fundamental info units.

**Units of measurement and equivalences**

To give us a basic thought of what we’ve simply talked about, a gig is able to storing up to a complete of a thousand information greater than a mega. Specifically, a giga is equal to 1,024 megabytes.

Starting from the** bytes as minimal unit**, the completely different units of measurement are expressed as follows:

- One Kilobyte is 1024 bytes
- One Megabyte is 1024 KB
- One Gigabyte is 1024 MB
- One Terabyte is 1024 GB
- One Petabyte is 1024 TB
- One Exabyte is 1024 PB
- One Zettabyte is 1024 EB
- One Yottabyte is 1024 ZB

These units of measure are sometimes used when shopping for a brand new laptop, pill, cellular machine, pendrive, exhausting drive or machine on the whole. Obviously, we’re not going to look for a similar** storage** on a smartphone than on a pc. Therefore, we should know these units of measurement and search for a tool that fits our particular wants, relying on what we use the machine for and if we’re going to retailer roughly issues.

Unit |
Symbol |
Equivalence |

1 kilobyte | kB | 1024 bytes |

1 megabyte | MB | 1024 KB |

1 gigabyte | GB | 1024 MB |

1 terabyte | TB | 1024 GB |

1 petabyte | PB | 1024 TB |

1 exabyte | EB | 1024 PB |

1 zettabyte | ZB | 1024 EB |

1 yottabyte | YB | 1024 ZB |

To measure the **contracted web connection velocity**, we use a measure primarily based on the bits transmitted per second, though it needs to be famous that in fiber optics and ADSL extra use is manufactured from** megabits per second (Mbps)** and gigabits per second (Gbps).

## How to calculate

Starting from the **bytes as minimal unit**, and taking into consideration that we’re speaking in decimal base, a gigabyte is the storage unit (GB), equal to 1,000,000,000 bytes. It shouldn’t be to be confused with the gibibyte (GiB), which is equal to 1024 MiB. The gigabyte (GB) equals 1000 MB. The latter is the one used for the storage capability or measurement of the information. A unit bigger than that is the Terabyte, more and more current in additional gadgets, equal to 1,000 GB.

Taking into consideration these differentiations, we’re going to see how we are able to simply go from one unit to one other by making their equivalence and taking into consideration what we depend on to make the conversion.

### Megabytes to gigabytes

In many circumstances, you will discover that the smallest unit of measure used (which doesn’t exist) is the megabyte, so it’s good to know what number of **megabytes are in a gigabyte** and even what number of are in a terabyte.

In order to make the equivalence of megabytes to gigabytes, we discover two methods of expressing ourselves, that are the decimal base (which begins from a base 10) and the binary base (which begins from a base 2).

Name | Decimal | Name | Binary unit |

Kilobyte (kB) | 10^{3} |
Kibibyte (KiB) | 2^{10} |

Megabyte (MB) | 10^{6} |
Mebibyte (MiB) | 2^{twenty} |

Gigabyte (GB) | 10^{9} |
Gibibyte (GiB) | 2^{30} |

Terabyte (TB) | 10^{12} |
Tebibyte (TiB) | 2^{40} |

In this manner, we discover the next equivalences relying on the bottom from which we begin and the unit of measurement, though on this case we are going to give precedence to the decimal base:

**1000 megabytes (MB) = 1 gigabyte (GB)**- 1024 mebibyte (MiB) = 1 gibibyte (GiB)
- 953,674 mebibyte (MiB) = 1 gigabyte (GB)

### Gigabytes to Terabytes

To make the transfer from gigabytes to terabytes, more and more utilized in completely different gadgets comparable to probably the most trendy exhausting drives, we’re going to proceed utilizing the 2 methods of expressing ourselves, that are the binary base and the decimal base.

**1000 gigabyte (GB) = 1 terabyte (TB)**- 1024 gibibyte (GiB) = 1 tebibyte (TiB)
- 931,323 gibibyte (GiB) = 1 terabyte (TB)

In most producers at present the decimal base is used because the unit of measurement, though computer systems are utilizing the binary base.

Although we’ve already mentioned it earlier than, it’s good to emphasize that ranging from the decimal system 1 GB is equal to 1000 MB and 1 TB is equal to 1000 GB. So 1GB = 1000MB and 1TB = 1000GB.

Terabytes | Gigabytes |

1 TB | 1000 GB |

2 TB | 2000 GB |

Three TB | 3000 GB |

Computers use the binary system, so it is vitally vital that when buying a brand new machine you actually know the quantity of storage they’re providing you to know what you’re going to have and you too can evaluate it with the true capability of your workforce.

1 KB (kilobyte) |
0.976563 KiB (kibityte) |

1 MB (megabyte) |
0.953674 MiB (mebibyte) |

1 GB (gigabyte) |
0.931323 GiB (gigibyte) |

1 TB (terabite) |
0.909495 TiB (tebibyte) |

**Gigabits per second to megabits per second**

Now that we’ve made the equivalence in units of measure within the case of storage gadgets or file capability, it’s vital to calculate the measure of transmission of the knowledge, which is the one utilized in **web speeds**.

The **gigabits per second **(Gbps) are the measure used to describe the bandwidth of an web connection comparable to fiber optic or the much less and fewer used ADSL.

We should know that 1 Gbps is equal to 1000 Mbps. When we discuss a 1 Gbps web connection, that is a lot greater than others comparable to 100 Mbps or 300 Mbps which are being supplied by completely different corporations. Specifically, with respect to 100 Mbps the velocity is 10 occasions greater, which signifies that it’s able to downloading or sending a file, relying on the case, in a lot much less time.

In the **web connections** Megabit per second is usually used as a measure, so 1000 megabits per second equals 1 gigabit per second. 1000 gigabits per second would, in your case, equal 1 terabit per second. So it could be 1000 Mbps = 1 Gbps. For reference, we should know that 10 Gbps is 1.25 GB / s. In the identical method, one gigabit per second is equal to 125 MB / s, because it have to be divided by 8.

Gigabit per second
1 Gbps |
Megabyte per second
125 MB / s |

2 Gbps | 250 MB / s |

3 Gbps | 375 MB / s |

4 Gbps | 500 MB / s |

5 Gbps | 625 MB / s |

6 Gbps | 750 MB / s |

7 Gbps | 875 MB / s |

8 Gbps | 1000 MB / s |

10 Gbps | 1250 MB / s |

The **gigabits per second** (We have already mentioned beforehand that within the case of the web we are going to begin from the bottom of the bits and never the bytes) they’re equal to** 1,000,000,000 bits**. A gigabit (Gb) is equal to 1/Eight of a gigabyte, because it have to be remembered {that a} byte is Eight bits.
