Convert between Joule and Kilojoule with step-by-step calculations.
Unit Information
Joule (J)
The SI derived unit of energy, work, or amount of heat.
System: SI
Kilojoule (kJ)
A metric unit of energy equal to one thousand joules.
System: SI
Conversion Process
This conversion uses Joule as the base unit. We'll first convert Joule to Joule, then convert from Joule to Kilojoule.
Step 1: Convert from Joule to Joule
1 × 1 = 1
Result: 1 Joule
Step 2: Convert from Joule to Kilojoule
1 × 0.001 = 0.001
Result: 0.001 Kilojoule
Direct Conversion Factor
1 ÷ 1,000 = 0.001
Direct conversion: 1 Joule = 0.001 Kilojoule
Joule (J)
System: SI
Definition:1 Joule is equal to the work done when a force of one Newton moves an object through a distance of one meter in the direction of the force (1 J = 1 N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second.
Origin: Named after the English physicist James Prescott Joule.
Common Usage: Widely used globally in science, engineering, and to measure the energy content of electricity (in kWh, derived from Joules).
