⚡ What is a Watt?

The Watt (W) is the standard unit of power in the International System of Units (SI). Named after James Watt, the Scottish engineer who helped develop the steam engine, this unit measures the rate of energy transfer or conversion.

  • 1 Watt = 1 Joule per second (1 W = 1 J/s)
  • Common Uses: Electrical devices, mechanical systems, heating appliances, and more.
  • Symbol: W

🔄 Conversion Formulas & Explanation

Here are the accurate formulas this tool uses to convert watts into other units:

⚙️ Watts to Horsepower (Mechanical)

  • Formula: 1 W = 0.00134102 HP
  • Horsepower is commonly used in automotive and industrial settings to describe the output of engines and motors.

⚡ Watts to Kilowatts

  • Formula: 1 W = 0.001 kW
  • Kilowatts are often used in electricity billing, solar energy systems, and power generation.

🔥 Watts to BTU/hr

  • Formula: 1 W = 3.41214 BTU/hr
  • British Thermal Units per hour are commonly used in heating, ventilation, and air conditioning (HVAC).

🔬 Watts to Calories/sec

  • Formula: 1 W = 0.2388459 cal/sec
  • Useful in thermodynamics and biological energy calculations.

Real-World Conversion Examples

To help you better understand the conversions, here are simple, everyday examples:

✅ Watts to Horsepower

  • A small vacuum cleaner uses about 1000 W.
  • 1000 W × 0.00134102 = 1.341 HP
  • This means the vacuum cleaner operates with roughly 1.34 horsepower.

✅ Watts to Kilowatts

  • A hair dryer might use 1800 W.
  • 1800 W ÷ 1000 = 1.8 kW
  • Useful for checking energy usage on your electric bill.

✅ Watts to BTU/hr

  • A space heater rated at 1500 W produces:
  • 1500 × 3.41214 = 5118.21 BTU/hr
  • This is essential in selecting heating units for home or office.

✅ Watts to Calories/sec

  • A lightbulb rated at 60 W generates:
  • 60 × 0.2388459 = 14.33 cal/sec
  • Relevant in science labs or biology to quantify energy output.
