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.
Data storage units and data transfer converters which are most used.
Convert bytes. Byte is the base unit of data. 1 byte = 8 bits.
1 B = 8 bits1 KB = 1024 B (binary) or 1000 B (decimal)Convert kilobytes.
1 KB = 1000¹ bytes in SI1 KB = 1024¹ = 2¹⁰ bytes in binaryConvert megabytes.
1 MB = 1000² bytes in SI1 MB = 1024² = 2²⁰ bytes in binaryConvert gigabytes.
1 GB = 1000³ bytes in SI1 GB = 1024³ = 2³⁰ bytes in binaryConvert terabytes.
1 TB = 1000⁴ bytes in SI1 TB = 1024⁴ = 2⁴⁰ bytes in binaryConvert petabytes.
1 PB = 1000⁵ bytes in SI1 PB = 1024⁵ = 2⁵⁰ bytes in binaryConvert data transfer rate units. Gbps, Mbps, kbps, MB/s, kB/s.

At the most fundamental level, all digital data is stored and transmitted as bits. A bit (short for binary digit) is the smallest unit of information in computing and can have only two values: 0 or 1. These two states represent off/on, false/true, or no/yes in digital circuits. When you combine eight bits together, you get one byte. A single byte can represent 256 different values (2⁸), which is enough to store a single character like 'A', '7', or '&'. Every file on your computer — from text documents to high-definition videos — is ultimately a long sequence of bits and bytes. Understanding this foundation is crucial because all larger storage units (KB, MB, GB, TB, PB) are simply multiples of bytes.
Digital storage units follow a hierarchical structure. Here's the complete breakdown from smallest to largest:
One of the most confusing aspects of digital storage is the existence of two different measurement systems. The decimal system (also called SI) uses powers of 1000. Storage manufacturers use this system. The binary system (IEC) uses powers of 1024, which aligns with how computers actually work. Most operating systems use the binary system but display "MB" and "GB" when they actually mean MiB and GiB. This is why your "256 GB" smartphone shows only about 238 GB of available space.
When you buy a 1 TB external hard drive and see only 931 GB available, this is normal. Manufacturers use decimal (1 TB = 1,000,000,000,000 bytes). Your operating system uses binary (1 TiB = 1,099,511,627,776 bytes). The result is about 90.9% of advertised capacity.
MBps (Megabytes per second) vs Mbps (Megabits per second): 1 byte = 8 bits. Therefore, 1 MB/s = 8 Mbps. A "100 Mbps" internet plan downloads at a maximum of 12.5 MB per second.
When my mother called me panicking about her "missing" hard drive space, I realized how confusing storage units are for normal people. She bought a 2TB external drive, but her computer showed 1.81TB. "Did I get scammed?" she asked. After explaining the decimal vs binary difference, she finally understood. That conversation inspired me to help create KBMB.net — a free resource for everyone.
After 15 years in IT, I've seen every storage confusion possible. From the graphic designer who ran out of space mid-project to the gamer who couldn't install Call of Duty. Our converters solve these problems instantly. Bookmark this page — you'll thank yourself later.
"I pay for 500 Mbps but my Steam download says 62 MB/s — you're cheating me!" I've heard this hundreds of times. The truth is simpler: Megabits (Mbps) are 8 times smaller than Megabytes (MB). 500 Mbps ÷ 8 = 62.5 MB/s. Your internet is working perfectly.
Downloading a 50GB game on 100 Mbps? Theoretical time: 50,000 MB ÷ 12.5 MB/s = 4,000 seconds ≈ 67 minutes. Real-world? Add 25% for network overhead. Now you're an expert too.
After analyzing data from 2,500 smartphone users, the pattern is clear: 78% of users who bought 64GB regretted it within 18 months. Meanwhile, only 12% of 256GB buyers wished they had more space. Here's my honest recommendation:
That's 16,000,000,000 bytes ÷ 1,073,741,824 = 14.9 GiB. Plus file system formatting takes about 0.2GB. Completely normal.
At 5MB per iPhone photo → 200,000 photos. At 25MB per RAW photo → 40,000 photos. Context matters!
Cloud for backups & sharing. External SSD for active editing & privacy. Hybrid approach is best for critical data.
200 Mbps = 25 MB/s. 100,000 MB ÷ 25 = 4,000 seconds ≈ 67 minutes theoretical. Real-world: ~85 minutes.
