Tips for Accurate Conversions
- Use decimal units (KB, MB, GB, TB) when comparing with manufacturer specifications or marketing materials
- Use binary units (KiB, MiB, GiB, TiB) when matching what your operating system displays in file managers
- For network speeds, remember that 1 byte = 8 bits (100 Mbps = 12.5 MB/s)
- When in doubt, check whether your source uses base-1000 or base-1024 calculations

Frequently Asked Questions
What is the difference between KB and KiB?
KB (Kilobyte) uses the decimal system: 1 KB = 1,000 bytes. This is the standard used by storage manufacturers and in most marketing materials.
KiB (Kibibyte) uses the binary system: 1 KiB = 1,024 bytes. This is what operating systems typically use internally and display in file managers.
The same pattern applies to MB/MiB, GB/GiB, TB/TiB, and so on. The "i" in the middle indicates binary (base-1024) measurement.
| Decimal | Binary | Difference |
|---|---|---|
| 1 KB = 1,000 B | 1 KiB = 1,024 B | 2.4% larger |
| 1 MB = 1,000,000 B | 1 MiB = 1,048,576 B | 4.9% larger |
| 1 GB = 1,000,000,000 B | 1 GiB = 1,073,741,824 B | 7.4% larger |
| 1 TB = 1,000,000,000,000 B | 1 TiB = 1,099,511,627,776 B | 10% larger |
Why does my hard drive show less space than advertised?
This is due to the decimal vs binary difference. When a manufacturer sells a "1 TB" drive, they mean 1,000,000,000,000 bytes (decimal). However, Windows displays storage in binary units, so that same drive shows as approximately 931 GiB.
Common examples:
- 500 GB drive → shows as ~465 GiB in Windows
- 1 TB drive → shows as ~931 GiB in Windows
- 2 TB drive → shows as ~1.82 TiB in Windows
- 4 TB drive → shows as ~3.64 TiB in Windows
Use this converter to see the exact relationship between advertised and displayed capacity for any drive size.
How do I convert internet speed to download time?
Internet speeds are measured in bits per second (Mbps), while file sizes are in bytes. Since 1 byte = 8 bits, you need to account for this conversion:
Convert File Size to Bits
Multiply your file size in bytes by 8 to get bits
Divide by Speed
Divide the result by your internet speed in bits per second
Get Download Time
The result is your download time in seconds
100 MB = 800 Mb (megabits)
800 Mb ÷ 100 Mbps = 8 seconds
Quick reference for common speeds:
- 100 Mbps = 12.5 MB/s (megabytes per second)
- 500 Mbps = 62.5 MB/s
- 1 Gbps = 125 MB/s
What is a nibble?
A nibble (also spelled "nybble") is 4 bits, or half a byte. It's commonly used in computing because one nibble can represent a single hexadecimal digit (0-F).
Binary Representation
Hexadecimal Digit
Common uses:
- Color codes in web design (each RGB component uses 2 nibbles)
- Binary-coded decimal (BCD) representation
- Low-level programming and hardware interfaces
- Network protocols and data encoding
Which units should I use for RAM?
RAM is measured in binary units. When your computer has "8 GB of RAM," it actually means 8 GiB (8,589,934,592 bytes). Memory manufacturers and operating systems both use binary measurement for RAM, so there's no discrepancy like with hard drives.
Common RAM sizes (binary):
| Advertised | Actual (Binary) | Bytes |
|---|---|---|
| 4 GB | 4 GiB | 4,294,967,296 bytes |
| 8 GB | 8 GiB | 8,589,934,592 bytes |
| 16 GB | 16 GiB | 17,179,869,184 bytes |
| 32 GB | 32 GiB | 34,359,738,368 bytes |
