Understanding Cloudflare workers Execution Duration

I’m trying to understand how to read the CF Workers Execution Duration.

I read this: https://developers.cloudflare.com/workers/observability/metrics-and-analytics/#duration-per-execution

But to be honest it’s very confusing.

For example, right now my 99th percentile is 0.103 GB-sec.

What does that mean? How can i convert that to something like “100ms response time”, which is easier to understand?
