About MB to GB
MB to GB is the conversionfromMB to GB.
To understandthe “MB” and“GB” better,letsfirstintroduce “byte”toyou. Accordingto Wikipedia,
a byte is a unitof digital informationthatusuallyconsistsof 8bits.In history,itwasthe numberof
bitsusedto encode asingle characterof textincomputers.Therefore, the byte isthe smallest
addressable unitof memorystorage inmanycomputerarchitectures.
Tip: A bit is a basic unitof digital information and computinginformation.Thename“bit”is derived
frombinary digit representing a logical statewith oneof two possiblevalues(e.g.0 or 1).
MB is a unitsymbol of megabyte that isa multiple of the unitbyte fordigital information.The unit
prefix “mega”isa multiplierof 1,000,000 (106
) inthe common decimal system. So,1megabyte is
one millionbytes. However, inbinarydigit, amegaisa multiplierof 1048576 (220
).That is,one
megabyte isequal to1048576 bytesof binarydigitinfo.

2. Tip: MB can also refer to megabit(Mbit) which is equal to 1,000,000 (106
) bit in the decimal system.
While in the binary system,thereis mebibit;the 1 megabit= 1048576 (220
) bit.
GB, similarly,isaunifyingsymbolof gigabyte whichisa multiple of 1,000,000,000 (109
) unitbytes
for digital informationinthe decimalsystem.Inthe binarysystem,one gigabyte is 1073741824 (230
)
bytes.
Tip: Similarly, GB sometimesalso refers to gigabit(Gbit) which is onebillion bits in a decimal system
and there is gibibitequaling to 1073741824 (230
) bits in a binary system.

Bytes to MB (Megabyte)
From the above definitionof MB,youcan know that 1MB is 1,000,000 (106
) bytesinthe decimal
systemwhile 1048576 (220
) bytesinthe binarysystem. In1998, the International Electrotechnical
Commission(IEC) proposedstandardsof binaryprefixesrequiringthe use of megabyte tostrictly
denote 10002
(106
) bytesand mebibyte todenote 10242
(220
) bytes. Thisproposal wasadoptedby
the IEEE, EU, ISOand NIST bythe endof 2009. Yet, the megabyte isstill beenwidelyusedfordecimal
and binarysystems.

How Many MB in a GB (MB to GB)
As forhow many MB are in a GB, how many MB in1 GB, how many MB in GB or how much MB in a
GB, youcan convertGB to MB basedonthe above base.
MB to GB Converter
Are there 1000 or 1024 MB in a GB? Or, how many MB per GB?In differentbase systems,the
answerisdifferent. Inthe decimal base system, itis 1000 MB to GB. That is,one GB isequal to 1000
MB.
1 GB = 1000 MB (=103
megabytes)
In the binarybase, 1 GB to MB is1024. In otherwords,1GB isequal to 1024 MB.
1 GB = 1024 MB (=210
megabytes)

Convert KB to MB
1 MB = 1000 KB (Decimal)
1 MB = 1024 KB (Binary)
So,as forKB vs MB, there are many questions.The followinglistthe commonones:
Q1: Whichone is biggerKB or MB? / What’sbigger MB or KB? / Is KB or MB bigger?
A1: MB isbigger.
Q2: Is KB bigger than MB?
A2: No,MB is biggerthanKB.
Q3: Whichislarger KB or MB?

4. A3: MB islarger.
Q4: Is KB smallerthan MB?
A4: Yes,it is.
Tip: MB andKB are usually used to describethe speed of data transfer.Kb/s,also known askbit/s,
refers to kilobit per second (kbps).Mb/s,also called Mbit/s,meansmegabitpersecond (Mbps).So,
kb/sto MB/s is 0.001 (10-3
).That is, 1 Mb/sequalsto 1000 kb/s.
