ps command "C" column

I read in some answers that "C" column gives a measure of intensity in the CPU usage by a process. Which is the scale for it? Does it give information on ratio between "expensive" and "cheap" operations in terms of consumed CPU?

Bye,

Hi,

C column means "processor utilization for scheduling ", so it shows the percentage of time in schedule spent on certain process. There were some problems with showing one digit utilization. The problem was caused by ps output formatting and insted of 3% (e.g.) ps shows 0%. Improved with PHCO_18446.
