Energy Converter

Welcome to the Energy Converter! This tool allows you to convert between common energy units: Joules (J), Kilojoules (kJ), Calories (cal), Kilocalories (kcal), British Thermal Units (BTU), Foot-Pounds (ft·lb), and Watt-hours (Wh).

Key Features:

• Live Updates: Conversions update in real-time as you type.
• User-Friendly: A clean and intuitive interface.
• Accurate Calculations: Based on standard conversion factors.
• Two-Way Conversion: Enter a value in any unit to see conversions.

Understanding Energy Units:

This converter uses the Joule (J), the standard SI unit of energy, as its base. Here's a brief overview:

• Joule (J): The fundamental SI unit of energy.
• Kilojoule (kJ): 1000 Joules. Commonly used in scientific contexts.
  \( kJ = \frac{J}{1000} \)
• Calorie (cal): The "small calorie." \( 1 cal \approx 4.184 J \)
  \( cal \approx \frac{J}{4.184} \)
• Kilocalorie (kcal): Often used in nutrition (also known as the "large calorie" or "food calorie"). 1 kcal = 1000 cal.
  \( kcal \approx \frac{J}{4184} \)
• British Thermal Unit (BTU): Commonly used in heating and cooling.
  \( BTU \approx \frac{J}{1055.06} \)
• Foot-Pound (ft·lb): The energy required to lift one pound one foot.
  \( ft·lb \approx \frac{J}{1.35582} \)
• Watt-hour (Wh): A unit of energy, especially for electrical energy. 1 Wh = 3600 J.
  \( Wh = \frac{J}{3600} \)

How to Use:

• Enter a value into any of the input fields.
• The other fields will update instantly.
• The result cards will also display the converted values.
