Latency to Distance Calculator

Network Latency & Distance

Selected Medium: ~67% speed of light
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
