Unit Converter FAQ
Can I convert kW, MW, kVA, MVA, and kvar?▼
Yes. Power units include W, kW, MW, horsepower, BTU/h, and refrigeration tons. Separate apparent- and reactive-power groups cover VA, kVA, MVA, var, kvar, and Mvar, while the power-factor calculator relates kVA, kW, and kvar.
Does it include data center and cooling calculations?▼
Yes. The guided calculators include PUE, DCiE, WUE, CUE, rack capacity, redundancy modules, SLA downtime, RAID capacity, cooling COP, chilled-water flow, and required cooling airflow.
Are my values uploaded?▼
No. Conversions and formulas run in your browser. Shareable settings are stored after the # symbol in the URL, so they are not sent as part of the HTTP request.
Can I use the results for engineering design?▼
The tool uses standard relationships and the parameters you enter, but it does not replace equipment data, local codes, safety factors, or review by a qualified professional.
