FREE TO START
All 15 converters and 5 core calculators are free forever, with no account and no ads. A one-time Lifetime Pro purchase unlocks the full toolkit. No subscription and no renewal.
ON THE FLOOR
- Three-phase rack power: verify real PDU draw before dense racks trip a breaker
- Breaker load headroom against the 80 percent continuous-load limit
- Thermal Delta-T across a server or aisle
- Required airflow and cooling tonnage for a given heat load
- Rack power density and structural floor loading
- Three-phase imbalance and feeder voltage drop
- Subnet host capacity
ACROSS THE FACILITY
- PUE and pPUE efficiency calculator
- UPS runtime calculator and generator fuel runway
- Liquid-cooling heat dissipation from flow rate and Delta-T
- Power capacity utilization and cooling N+1 headroom
- Availability and annual downtime budget
- Stranded capacity, return temperature index
- Water usage effectiveness and energy reuse factor
FOR THE BUSINESS CASE
- Fully burdened TCO per rack
- Annual energy cost and efficiency ROI payback
- Cost of downtime and build cost per MW
- Carbon usage effectiveness and carbon cost
- Revenue yield per kW and EBITDA per MW
15 LIVE CONVERTERS
Amps to kilowatts, kVA to kilowatts, power and cooling, energy, temperature, airflow, liquid flow, static pressure, water pressure, rack units, length, area, weight, data size, and throughput. Edit any linked field and the remaining units update immediately.
BUILT FOR REAL OPERATIONS
- Works fully offline, with no account or cloud dependency
- Facility data stays on your device
- Shows the formula behind every calculator
- Save multiple facility profiles with reusable site defaults
