Formulas

Core equations used by this converter.

FormulaP(kW) = E(kJ) ÷ t(s)

iDC and resistive AC use PF = 1. Single-phase: multiply by PF. Three-phase line-to-line: include √3. Prefer RMS voltage and current for AC.

How to use

Take energy in kilojoules.

Take time in seconds.

Divide: kW = kJ / s.

No rate required for that path.

Example conversions

Common values with formula and result.

60 kJ over 60 s

P = 60 ÷ 60 = 1 kW

1 kW

3600 kJ over 60 s

P = 3600 ÷ 60 = 60 kW

60 kW

100 kJ over 10 s

P = 100 ÷ 10 = 10 kW

10 kW

Definition: **Kilojoule (kJ)** — energy (1000 J). **Kilowatt (kW)** — power (1000 W = 1000 J/s).
What it calculates: Convert kilojoules (kJ) to kilowatts (kW). Power needs time: kW = kJ ÷ s. Formula, steps, and examples.
Inputs: Values required by the selected conversion mode
Outputs: Converted result in the target unit or format
Formula: P(kW) = E(kJ) ÷ t(s)
Assumptions: Conversion runs locally in the browser; values are not uploaded.
Uses the formulas documented on this page.
Units: Amps × Volts
Boundary conditions: Empty or invalid input yields no valid result.
Out-of-range values may be rejected by the tool runtime.
Example: 60 kJ over 60 s → 1 kW
Validation cases: 60 kJ over 60 s → 1 kW
3600 kJ over 60 s → 60 kW
100 kJ over 10 s → 10 kW
