Common Conversions:
• Watts: ${watts.toFixed(3)} W
• Kilowatts: ${(watts / 1000).toFixed(6)} kW
• Horsepower: ${(watts / 745.7).toFixed(6)} hp
• Metric HP: ${(watts / 735.5).toFixed(6)} PS
• BTU/hour: ${(watts / 0.293071).toFixed(3)} BTU/h

Energy Relationships:
• Power × Time = Energy
• 1 kW for 1 hour = 1 kWh = 3.6 MJ
• 1 hp ≈ 746 W (mechanical)
• 1 PS ≈ 736 W (metric)`
