| Unit | Bits | Bytes | Kilobytes | Megabytes | Gigabytes | Terabytes |
|---|
Decimal uses base-10 (1KB=1000B), Binary uses base-2 (1KiB=1024B)
Hard drives use decimal, RAM uses binary. Know the difference!
Network speeds are in bits per second, storage in bytes
Mobile data plans typically use decimal measurements

KB (Kilobyte) = 1,000 bytes (decimal system), while KiB (Kibibyte) = 1,024 bytes (binary system). Storage manufacturers typically use decimal, while operating systems use binary, which explains why a "1TB" drive shows as "931GB" in Windows.
In the decimal system: 1 GB = 1,000 MB. In the binary system: 1 GiB = 1,024 MiB. This distinction is crucial for accurate storage calculations and understanding reported vs actual storage capacities.
Use binary (1024-based) for RAM, file sizes, and operating system reporting. Use decimal (1000-based) for storage devices, network speeds, and manufacturer specifications. Our tool handles both for complete accuracy.
1MB: A typical high-quality photo | 1GB: About 250 songs or 300 photos | 1TB: Approximately 250,000 photos or 17,000 hours of music | 1PB: The entire printed collection of the US Library of Congress.
