unit

Joules (J) → Joules (J):
$\text{Value in Joules} = \text{Input Value}$
Kilojoules (kJ) → Joules (J):
$\text{Value in Joules} = \text{Input Value} \times 1000$
Calories (cal) → Joules (J):
$\text{Value in Joules} = \text{Input Value} \times 4.184$
Kilocalories (kcal) → Joules (J):
$\text{Value in Joules} = \text{Input Value} \times 4184$
Watt-hours (Wh) → Joules (J):
$\text{Value in Joules} = \text{Input Value} \times 3600$
Kilowatt-hours (kWh) → Joules (J): $\text{Value in Joules} = \text{Input Value} \times 3600000$

Joules → Kilojoules (kJ):
$\text{Value in kJ} = \text{Value in Joules} \div 1000$
Joules → Calories (cal):
$\text{Value in cal} = \text{Value in Joules} \div 4.184$
Joules → Kilocalories (kcal):
$\text{Value in kcal} = \text{Value in Joules} \div 4184$
Joules → Watt-hours (Wh):
$\text{Value in Wh} = \text{Value in Joules} \div 3600$
Joules → Kilowatt-hours (kWh):
$\text{Value in kWh} = \text{Value in Joules} \div 3600000$
