Limitations to know
- Air-conditioner “tons” describe cooling capacity, not the electricity the unit uses.
- Results are shown to up to 10 significant digits; extremely large or small values switch to scientific notation (e.g. 1.5e-12).
Privacy: Power Converter runs entirely in your web browser. Your Number data is not uploaded, stored or shared, and nothing about its contents is sent to analytics.
