Complete collection of data storage and transfer rate converters at KBMB.net. Convert between bits, bytes, KB, MB, GB, TB, PB with decimal (SI) and binary (IEC) options. 50+ popular converters trusted by professionals worldwide.

Popular Data Units Converters

Data storage units and data transfer converters which are most used.

💾 Bytes (B)

Convert bytes. Byte is the base unit of data. 1 byte = 8 bits.

1 B = 8 bits
1 KB = 1024 B (binary) or 1000 B (decimal)

Bytes to KB Bytes to MB Bytes to GB KB to Bytes MB to Bytes GB to Bytes

📁 Kilobytes (KB)

Convert kilobytes.

1 KB = 1000¹ bytes in SI
1 KB = 1024¹ = 2¹⁰ bytes in binary

KB to MB KB to GB KB to TB MB to KB GB to KB TB to KB

📀 Megabytes (MB)

Convert megabytes.

1 MB = 1000² bytes in SI
1 MB = 1024² = 2²⁰ bytes in binary

MB to GB MB to TB MB to KB GB to MB TB to MB MB to Bytes

💿 Gigabytes (GB)

Convert gigabytes.

1 GB = 1000³ bytes in SI
1 GB = 1024³ = 2³⁰ bytes in binary

GB to MB GB to TB GB to KB MB to GB TB to GB GB to Bytes

💽 Terabytes (TB)

Convert terabytes.

1 TB = 1000⁴ bytes in SI
1 TB = 1024⁴ = 2⁴⁰ bytes in binary

TB to GB TB to MB TB to PB GB to TB MB to TB PB to TB

🗄️ Petabytes (PB)

Convert petabytes.

1 PB = 1000⁵ bytes in SI
1 PB = 1024⁵ = 2⁵⁰ bytes in binary

PB to TB PB to GB TB to PB GB to PB

⚡ Data Transfer Rate

Convert data transfer rate units. Gbps, Mbps, kbps, MB/s, kB/s.

1 MB/s = 8 Mbps
1 Gbps = 1000 Mbps

Mbps to MB/s Gbps to MB/s Mbps to kbps Gbps to Mbps MB/s to Mbps kB/s to kbps

🎲 Bit Conversions

Bits (b), Kilobits (kbit), Megabits (Mbit), Gigabits (Gbit)

1 byte = 8 bits
1 Mbit = 1000 kbit

Bits to Bytes kbit to Mbit Mbit to Gbit MB to Mbit Mbit to MB Gbit to GB

🔢 IEC Prefix Data Units

Kibibytes (KiB), Mebibytes (MiB), Gibibytes (GiB), Tebibytes (TiB)

1 KiB = 1024 bytes
1 MiB = 1024 KiB
1 GiB = 1024 MiB

KiB to MiB MiB to GiB GiB to TiB MiB to MB GiB to GB TiB to TB

Bits and Bytes - The Fundamentals

The bit (binary digit) is the smallest unit of data, representing a 0 or 1. Eight bits make one byte, enough to store a single character. All larger storage units are built from bytes.

Decimal (SI) vs Binary (IEC) Systems

Two main systems for measuring data:

Decimal (SI): Based on powers of 1000. Used by hard drive manufacturers, cloud storage. 1 KB = 1000 bytes, 1 MB = 1000 KB, 1 GB = 1000 MB.
Binary (IEC): Based on powers of 1024. Used by operating systems. 1 KiB = 1024 bytes, 1 MiB = 1024 KiB, 1 GiB = 1024 MiB.

This explains why a "1 TB" drive shows ~931 GB in Windows.

Quick Reference Table

Unit	Decimal (bytes)	Binary (bytes)
1 KB / KiB	1,000	1,024
1 MB / MiB	1,000,000	1,048,576
1 GB / GiB	1,000,000,000	1,073,741,824
1 TB / TiB	1,000,000,000,000	1,099,511,627,776

Data Transfer Rate Units

Network speeds in bits per second, file transfers in bytes per second. 1 byte/s = 8 bits/s. Common: Mbps (Megabits/s), MB/s (Megabytes/s).

Storage Device Capacity

Advertised (decimal) vs actual (binary): 256 GB → ~238 GB, 512 GB → ~476 GB, 1 TB → ~931 GB, 2 TB → ~1.81 TB.

Real-World File Sizes

MP3 song: 4-10 MB
HD movie: 2-4 GB
Windows 11: 20-25 GB
AAA game: 50-150 GB

Frequently Asked Questions

Q: Why does my 256 GB phone show only 238 GB? A: Decimal-binary gap (256 GB decimal = 238 GiB) plus OS space.

Q: How many MB in 1 GB for mobile plans? A: Decimal: 1 GB = 1,000 MB.

Q: Easy conversion? A: Multiply decimal by 0.93 to get binary GB (GiB).
