Does this include propagation delay?

No, this only calculates transmission delay (time to push the bits onto the wire). Total latency also includes propagation delay, which depends on distance and the medium's signal speed.

Why convert bytes to bits first?

Bandwidth is conventionally measured in bits per second, while packet sizes are usually given in bytes, so multiplying by 8 puts both values in the same unit before dividing.

Packet Transmission Time Calculator

Calculate the time required to transmit a single packet across a network link, based on the packet size and the available bandwidth. A fundamental calculation for network performance and latency analysis.
