KB and kB describe kilobyte - a unit of info or computer system storage same to either 1,024 bytes (210) or 1,000 bytes (103), depending upon context.
You are watching: What is bigger a megabyte or a kilobyte
MB refers to megabyte - a unit of details or computer storage same to one of two people 1,048,576 bytes (220) or 1,000,000 bytes (106), relying on context. A megabyte has roughly 1,000 (or 1,024 to it is in precise) kilobytes.

Difference in between kB and also kb, MB and Mb
kb is kilobits and kB is kilobytes. While MB is megabytes, Mb refers to Megabits. 1 byte has 8 bits. File sizes space usually express in KB and also MB whereas kb and Mb are regularly used to express data move speeds (such as a 54 Mbps wireless router or 3G or 4G connection speeds).
All devices of info volume
A little bit is the the smallest unit that information. That is one of two people a 0 or 1. A byte is the following smallest unit, and is same to 8 bits. All other units of information are acquired from bits and bytes, and represent a certain variety of bits (or bytes).
Each unit includes a prefix and also suffix. The suffix denotes even if it is the unit is representing bits or bytes; the prefix denotes how numerous bits/bytes space being conveyed. There room two species of prefixes:
Kilo-, mega-, giga-, tera-, peta-: these space the prefixes many widely used. They represent aggregations in devices of 1,000. Kilo- is 10001 Mega- is 10002 i.e., 1 million Giga- is 10003 i.e., 1 billion Tera- is 10004 i.e., 1 sunshine Peta- is 10005 i.e., 1 quadrillion Kibi-, mebi-, gibi-, tebi-, pebi-:these prefixes signify aggregations in devices of 1024. Because computing provides a binary system, the totals for units of storage are always in powers of 2. 1024 is 210. Kibi- is 10241 Mebi- is 10242 Gibi- is 10243 Tebi- is 10244 Pebi- is 10245Applying this sample we have the right to see that
| Kilobit (Kb or kb) | 1000 | 1 | 1000 bits |
| Megabit (Mb) | 1000 | 2 | 10002 bits; or 1000 kilobits |
| Gigabit (Gb) | 1000 | 3 | 10003 bits; or 1000 megabits |
| Terabit (Tb) | 1000 | 4 | 10004 bits; or 1000 gigabits |
| Kilobyte (KB or kB) | 1000 | 1 | 1000 bytes |
| Megabyte (MB) | 1000 | 2 | 10002 bytes; or 1000 kilobytes |
| Gigabyte (GB) | 1000 | 3 | 10003 bytes; or 1000 megabytes |
| Terabyte (TB) | 1000 | 4 | 10004 bytes; or 1000 gigabytes |
| Kibibyte (KiB) | 1024 | 1 | 1024 bytes |
| Mebibyte (MiB) | 1024 | 2 | 10242 bytes; or 1024 kibibytes |
| Gibibyte (GiB) | 1024 | 3 | 10243 bytes; or 1024 mebibytes |
| Tebibyte (TiB) | 1024 | 4 | 10244 bytes; or 1024 gibibytes |
Kbps vs. Mbps and Other Data rate Units
Data rate units are stood for as info per second. For example, Kilobits per second supplies the symbol kbps, kbit/s or kb/s; Kilobytes every second is written as kB/s and Mbps stands for Megabit per second.

The notation complies with this convention:
usage lower-case b for bits and upper-case B because that bytes. E.g. MB/s is megabyte per second and Mbps is megabit every second. K represents kilo and may be provided in upper or reduced case. M means mega, G for giga, T for tera. So 1 Gbps is 1 gigabit every second. These units room aggregated in multiples that 1000. Ki stands for kibi, for this reason KiB/s is kibibytes per second while Kib/s or Kibit/s is kibibit per second. An in similar way Mi stands for Mebi, Gi for Gibi, and also Ti for Tebi. The units room aggregated in powers of 2, specifically 210.| bit/s | bit every second | 1 |
| B/s | byte every second | 8 |
| kbit/s | kilobit every second | 1,000 |
| Kibit/s | kibibit every second | 1,024 |
| kB/s | kilobyte per second | 8,000 |
| KiB/s | kibibyte every second | 8,192 |
