Latency to Distance Calculator
Network Latency & Distance
Selected Medium: ~67% speed of light
Speed: 200,000,000 m/s
Speed: 200,000,000 m/s
How to Use
Calculation Types
- Latency → Distance: Calculate physical distance from network latency
- Distance → Latency: Calculate expected latency for given distance
Understanding Results
- Round-Trip Time (RTT): Time for signal to travel to destination and back
- Propagation Latency: Pure signal travel time without processing
- Processing Delay: Time spent in routers, switches, and equipment
- Efficiency: How close to theoretical speed of light minimum
Transmission Mediums
- Fiber Optic: ~67% speed of light, most common for long distance
- Copper Cable: ~53% speed of light, short distance networking
- Coaxial: ~67% speed of light, cable TV/internet
- Radio/Microwave: ~100% speed of light, wireless links
- Satellite: ~100% speed of light, but very long distance
Latency Categories
- <1ms: Local network (same building)
- 1-20ms: Regional (same city/state)
- 20-50ms: National (same country)
- 50-100ms: Continental
- 100-200ms: Intercontinental
- >200ms: Satellite or very long distance
Applications
- Network Troubleshooting: Identify distance vs processing delays
- CDN Planning: Optimize content delivery locations
- Gaming/Real-time: Understand latency limitations
- Financial Trading: Calculate speed-of-light advantages
