CPU utilization memory in MB in Ubuntu
 

could anyone tell me how to check how much Memory in MB is needed to open a webpage www.yahoo.com in Ubuntu machine. I need total calculation but not in percantage.

you can check the used memory of the browser before and after opening that page.

is there any way to calculate this from command line?

calculate what? the content of a generated page on a remote server? The only way is to get/download it, and measure the memory usage. But probably someone has a better idea.

Out of pure interest, can I ask why you want to want/need to do this? Your reason may have an impact on the solution.

I am intersted to know how much memory(RAM) is used while we open a page in the browser.Is there any command that can show total memory is used in MB?I can use htop command. But it shows only in percentage of memory(RAM) with many process.

The top command provides you information on the memory used/consumed by each process in KB. You can use the e command within top to cycle through viewing the memory info in KB/MB/GB/PB.
