Yeah, that initial expression gives you the CPU usage in percent of a CPU core (not seconds or MHz). So if you have 1 core and it's 100% used, you will get an output value of 100, for 2 fully used cores you would get 200, etc.
It doesn't seem like cAdvisor exposes any clock speed (MHz) metrics, see also https://github.com/google/cadvisor/issues/2354. Though the Node Exporter does (see https://www.robustperception.io/cpu-frequency-scaling-metrics-from-the-node-exporter), but how much sense it makes to combine that with the container-level CPU usage data, I'm not sure.
