# Berlin, Germany → Los Angeles, USA RTT

🇩🇪 **Berlin, Germany (BER)** → 🇺🇸 **Los Angeles, USA (LAX)**

Measurement round: `2026-08-16T04:07:28Z`.

In round 2026-08-16T04:07:28Z, the Berlin-to-Los Angeles ICMP echo route averaged 140.9ms, with all 50 samples between 133.87ms and 162.61ms and zero packet loss.

This route ranks 11th among the 19 outbound paths from Berlin in the same round. Its 5.85ms standard deviation is approximately 4.2% of the average, above the 3.28% median standard-deviation-to-average ratio, making it one of the more variable routes in the set.

Given a great-circle distance of 9,331.9km, the RTT is 1.54 times above the theoretical fiber-floor estimate of 91.39ms, corresponding to 64.9% fiber efficiency. The 28.74ms gap between minimum and maximum samples is worth noting for a route that otherwise completed every probe without loss.

## About This Measurement

Published RTT reflects best-case backbone path behavior measured with ICMP echo probes between PoPs. End-user latency also depends on local access networks, congestion, routing policy, and traffic engineering. None of these values is an SLA.

The measurement round behind this page is published as open data under **CC BY 4.0** in the [Hats Network latency dataset](/opendata/latency/). Per-pair files are available at `/opendata/latency/latest/pairs/ber-lax.pings.{csv,json,yaml}`. When citing, include the route, the measurement round timestamp, and the dataset version — for example: "Hats Network latency dataset, Berlin → Los Angeles round 2026-08-16T04:07:28Z, CC BY 4.0".
