How it works
- It supports 8 units: W (watt), kW, MW, PS (metric horsepower), hp (mechanical horsepower), kcal/h, BTU/h, and erg/s.
- Conversions are based on the watt (W), using the internationally accepted definitions: 1 kW = 1000 W, 1 PS = 735.49875 W, 1 hp = 745.6999 W, and 1 kcal/h = 1.16222 W.
- To use it, enter the value you want to convert and choose its unit from the dropdown. Once entered, conversions for every unit are listed in a table.
- The converted value in watts (W) is shown prominently at the top as the representative figure. Extremely large or small values switch to exponential notation.
- Displayed digits are automatically rounded for readability. Note the rounding when an exact value is required.
- It is useful for comparing the capacity of air conditioners and heaters (kW, BTU/h, kcal/h) and the output of cars and engines (PS, hp, kW).
