Propagation Delay Calculator

Find signal propagation delay along a cable.

Propagation delay (ns) 505.4

Formula: delay = distance / (velocity factor * c)

Step-by-step with your numbers:

1. Values used:

2. Distance = 100

3. Velocity factor = 0.66

5. Propagation delay = 505.4ns

Did we solve your problem today?

Signals travel slower than light in a cable, set by its velocity factor.

The math behind it

delay = distance / (velocity factor x speed of light). Typical coax has a velocity factor around 0.66.

100 m of cable (VF 0.66) gives about 505 ns.

Why does it matter?

It affects timing in high-speed buses, networks and RF systems.
