Free Power and Data Center Calculators
Quick, honest math for early planning: size behind-the-meter generation, convert megawatts to gas, see what PUE costs, estimate cooling water and size off-grid solar. Every tool shows its formula, runs in your browser and sends nothing anywhere.
All calculators
Behind-the-Meter Power Sizer
Turn an IT load into facility megawatts, generator count with redundancy, and daily gas burn.
Open the calculator →Gas-to-Power Calculator
Convert megawatts to MMBtu and Mcf per day, or find how many megawatts a gas stream can make.
Open the calculator →PUE and Energy Cost Calculator
See facility load, overhead power and the yearly energy bill for any IT load and PUE.
Open the calculator →Data Center Water Use Calculator
Estimate daily and yearly cooling water from IT load and WUE, in liters and gallons.
Open the calculator →Off-Grid Solar and Battery Sizer
Size the solar array and battery bank for a remote site, camera, radio or edge server.
