Latency Calculator

Break down one-way latency into propagation, transmission, and medium base delay.

Propagation5 ms
Transmission0.01 ms
Base0 ms
Total5.01 ms

How to read the result

Propagation = distance / medium speed. Transmission = packet bits / rate. Base = medium RTT floor (Wi-Fi, satellite).

Example

1000 km fiber + 1500 B @ 1 Gbps → ~5 ms

FAQ

One-way or round-trip?

This shows one-way propagation + transmission plus the medium base. Double propagation for a rough RTT.

Why is satellite so slow?

GEO satellites add ~480 ms base delay from the ~72,000 km round trip to orbit and back.
