Thank you all for your responses:

Merrell, Vince
Steve Elliott
Shankar Chandramouly
Bob Hendley
Bob Rahe
Matt Reynolds
Jim Taylor
Allan West
Walter Reed
Gary Jarrell

Almost all of the above suggested to ask Sun helpdesk or to use the figures
of relatively similar or greater machines (Jim Taylor). Shankar Chandramouly
and Bob Rahe sent me the formula that converts Power (in Watts) to BTU.
This formula can also be found at Sun Microsystems Data Center Site
Planning Guide (
and is as follows:

3412.97 * kW = BTU/hr
