Watt-hours to Joules Converter
Convert watt-hours to joules and other energy units. Calculate energy conversions between watt-hours, joules, kilowatt-hours, calories, and more.
Step 1: Enter Energy Value
Understanding Watt-hours and Joules
Watt-hour (Wh): A unit of energy equal to one watt of power expended for one hour.
Joule (J): The SI unit of energy equal to the work done when a force of one newton moves its point of application one meter.
Conversion: 1 Wh = 3600 J
Step 2: Calculation Options
Key Conversion Formulas
Wh to J: J = Wh × 3600
J to Wh: Wh = J ÷ 3600
kWh to J: J = kWh × 3,600,000
Cal to J: J = cal × 4.184
BTU to J: J = BTU × 1055.06

Energy Conversion Formulas
Watt-hours to Joules
Formula: Joules = Watt-hours × 3600
Example: 100 Wh = 100 × 3600 = 360,000 J
Joules to Watt-hours
Formula: Watt-hours = Joules ÷ 3600
Example: 360,000 J = 360,000 ÷ 3600 = 100 Wh
Calories to Joules
Formula: Joules = Calories × 4.184
Example: 100 cal = 100 × 4.184 = 418.4 J
BTU to Joules
Formula: Joules = BTU × 1055.06
Example: 1 BTU = 1 × 1055.06 = 1,055.06 J
Electronvolts to Joules
Formula: Joules = Electronvolts × 1.602176634×10⁻¹⁹
Example: 1 eV = 1.602176634×10⁻¹⁹ J
