Snaplex API (monitor Node mem_used and cpu_used)

I am trying to get how much Machine memory is used (memory and CPU) average per day, but from the API I am getting the results in decimal numbers. My question is what format are the numbers in bytes, kilobytes… etc. or percentages as I need to compare with the current configuration of the Machine. Below is an attachment of how I get the results.stats community

mem_used and cpu_user are percentages.

Thank you Roger
