Power conversion table
A compact cross-unit reference for the most useful power units. Values are computed from the same unit registry used by the interactive pair converters, so the family table and exact calculator routes cannot silently drift apart.
One-unit matrix
What 1 unit equals
Read across a row as “1 row unit equals the value shown in the column unit.” Temperature rows use the exact Celsius/Fahrenheit/Kelvin relationships rather than a simple multiplicative factor.
| 1 unit | W | kW | hp |
|---|---|---|---|
| 1 Watts | 1 | 0.001 | 0.0013410221 |
| 1 Kilowatts | 1,000 | 1 | 1.3410220896 |
| 1 Mechanical horsepower | 745.6998715823 | 0.7456998716 | 1 |

Truth boundary
Reference, not measurement advice.
The table performs deterministic mathematical conversion only. It does not establish measurement accuracy, calibration, suitability, legal metrology or domain-specific tolerance.
