Understanding Bit Rate Units
The Bit vs. Byte Difference:
A bit (b) is the smallest unit of data (a 0 or 1). A byte (B) equals 8 bits and represents one character of text.
8 bits = 1 byte means:
- 8 Mbps = 1 MB/s
- 100 Mbps = 12.5 MB/s
- 1 Gbps = 125 MB/s
Common Prefixes:
Decimal (Base 10)
- kilo (K) = 1,000 (10³)
- mega (M) = 1,000,000 (10⁶)
- giga (G) = 1,000,000,000 (10⁹)
- tera (T) = 1,000,000,000,000 (10¹²)
Binary (Base 2)
- kibi (Ki) = 1,024 (2¹⁰)
- mebi (Mi) = 1,048,576 (2²⁰)
- gibi (Gi) = 1,073,741,824 (2³⁰)
- tebi (Ti) = 1,099,511,627,776 (2⁴⁰)
Important to Know:
- Internet service providers (ISPs) advertise speeds in bits per second (Mbps)
- Download managers and browsers display speeds in bytes per second (MB/s)
- Network hardware specifications use bits (Mbps, Gbps)
- File sizes are measured in bytes (KB, MB, GB)

Why Speeds Differ
Even with a high-speed connection, you might not achieve the maximum advertised speeds due to:
- Network congestion at peak usage times
- Wi-Fi limitations compared to wired connections
- Server capacity at the source you're connecting to
- Distance from ISP infrastructure (e.g., DSL speeds)
- Protocol overhead reducing effective throughput
- Hardware limitations in your devices
A 100 Mbps connection typically delivers about 90-95 Mbps in ideal conditions due to protocol overhead.

Common Conversion Formulas
| From | To | Formula |
|---|---|---|
| Bits per second (bps) | Bytes per second (B/s) | B/s = bps / 8 |
| Megabits per second (Mbps) | Kilobytes per second (KB/s) | KB/s = Mbps × 125 |
| Download time | File size (bytes), Speed (bps) | Time (seconds) = Size × 8 / Speed |
