Data Storage and Transfer Unit Converter
When using computers, smartphones, cloud storage, or internet services, have you ever wondered:
- Why does a “100 Mbps broadband” connection only give a download speed of about 12.5 MB/s?
- Why does a hard drive labeled 1 TB show less than 1000 GB in your operating system?
- What’s the actual difference between Kb and KB?
The root cause lies in two common sources of confusion:
- The distinction between bits (bit) and bytes (Byte)
- The difference between decimal (SI) and binary (IEC) standards
To solve this problem, we’ve developed a professional Data Unit Conversion Tool that supports intelligent conversion among the following 10 commonly used units:
- Bit series (lowercase): b (bit), Kb, Mb, Gb, Tb
- Byte series (uppercase): B (Byte), KB, MB, GB, TB
✅ By default, the tool uses the decimal (SI) standard (1 KB = 1,000 B), but also offers an optional binary (IEC) mode (1 KiB = 1,024 B) to suit different scenarios.
🔁 Core Conversion Formulas
1. Relationship Between Bits and Bytes
- 1 Byte (B) = 8 bits (b)
Therefore:B = b ÷ 8b = B × 8
2. Decimal (SI) Standard
(Used for hard drives, network bandwidth, etc.)
| Unit | Conversion Relationship |
|---|---|
| 1 Kb | = 1,000 b |
| 1 Mb | = 1,000 Kb |
| 1 Gb | = 1,000 Mb |
| 1 Tb | = 1,000 Gb |
| 1 KB | = 1,000 B |
| 1 MB | = 1,000 KB |
| 1 GB | = 1,000 MB |
| 1 TB | = 1,000 GB |
3. Binary (IEC) Standard
(Used by operating systems, memory, etc.—optional mode)
| Unit | Conversion Relationship |
|---|---|
| 1 KiB | = 1,024 B |
| 1 MiB | = 1,024 KiB |
| 1 GiB | = 1,024 MiB |
| 1 TiB | = 1,024 GiB |
💡 Quick Tip:
- Network bandwidth (e.g., 100 Mbps) uses lowercase b for bits
- File sizes (e.g., 500 MB) use uppercase B for Bytes
→ Hence: 100 Mbps ÷ 8 = 12.5 MB/s (maximum theoretical download speed)
💾 Common Data Unit Reference Table
(Based on decimal SI standard: 1 KB = 1,000 B, 1 Kb = 1,000 b)
| Unit | bits (b) | Bytes (B) | KB | MB | GB | TB |
|---|---|---|---|---|---|---|
| 1 b | 1 | 0.125 | 1.25e-4 | 1.25e-7 | 1.25e-10 | 1.25e-13 |
| 1 Kb | 1,000 | 125 | 0.125 | 1.25e-4 | 1.25e-7 | 1.25e-10 |
| 1 Mb | 1e6 | 125,000 | 125 | 0.125 | 1.25e-4 | 1.25e-7 |
| 1 Gb | 1e9 | 1.25e8 | 125,000 | 125 | 0.125 | 1.25e-4 |
| 1 Tb | 1e12 | 1.25e11 | 1.25e8 | 125,000 | 125 | 0.125 |
| 1 B | 8 | 1 | 0.001 | 1e-6 | 1e-9 | 1e-12 |
| 1 KB | 8,000 | 1,000 | 1 | 0.001 | 1e-6 | 1e-9 |
| 1 MB | 8e6 | 1e6 | 1,000 | 1 | 0.001 | 1e-6 |
| 1 GB | 8e9 | 1e9 | 1e6 | 1,000 | 1 | 0.001 |
| 1 TB | 8e12 | 1e12 | 1e9 | 1e6 | 1,000 | 1 |
✅ All values in this table are calculated using the decimal SI standard.
✅ For binary conversions (e.g., 1 GB = 1,024 MB), please switch to “Binary Mode” in the tool.
