How this calculator estimates results
- Uses fixed conversion constants: 1 ton = 12,000 BTU/hr and 1 kW = 3,412.14163 BTU/hr.
- Converts from the selected input mode to BTU/hr, then derives tons and kW from BTU/hr.
- Applies selected decimal rounding consistently across all outputs.

Common ranges and tips
- Use unrounded values during intermediate engineering checks when possible.
- Confirm manufacturer ratings use the same units before comparing equipment.
- Pair tonnage outputs with airflow checks in the CFM per Ton Calculator.

FAQ
One ton of cooling is 12,000 BTU/hr.
Different specs and utility analyses use different units, so conversion helps compare systems quickly.
Treat this as an estimate/conversion aid. Final documentation should follow project standards and manufacturer data.
Rounding improves readability but can hide precision; use more decimals when you need tighter checks.
Disclaimer: Use results for planning only. Final design and installation decisions must follow local code and manufacturer documentation.
