Work Converter
Converts energy or work between joules, kilojoules, calories, kilocalories, watt-hours, kilowatt-hours, and foot-pounds. 1 kWh converts to 3600000 J.
What this calculator does
The Work Converter estimates your result instantly from the values you enter, using standard math & conversions formulas. Converts energy or work between joules, kilojoules, calories, kilocalories, watt-hours, kilowatt-hours, and foot-pounds. 1 kWh converts to 3600000 J. Calculations run in your browser, so nothing you type is sent to a server, and the output is an estimate rather than a certified or official figure.

About Work Converter
The Work Converter changes a work or energy value from one unit to another. It supports joules, kilojoules, calories, kilocalories, watt-hours, kilowatt-hours, and foot-pounds. Choose the From and To units and enter the amount.
Formula & Mathematical Calculation
Converted Value = f(Work / Energy, From, To)
Calculated according to standard math formulas implemented in the calculator core.
Calculation Example
Enter 1, set From to kWh and To to J, then click Calculate. The Converted Value box shows:
3600000 J
The note reads: 1 kWh equals 3600000 J.
Key Benefits
- Converts work and energy across seven units
- Supports J, kJ, cal, kcal, Wh, kWh, and ft-lb
- Uses fixed physical factors relative to the joule
- Shows the result to six decimals with the target unit
How to Use this Calculator
-
Enter the value
Type the work or energy amount into the Work / Energy field. -
Choose units
Select the source unit in From and the target unit in To. -
Calculate and read
Click Calculate and read the Converted Value box.
Assumptions & Limitations
What the calculation assumes
- Every value you enter is treated as an exact, known amount.
- Any rate or interval you enter is assumed to hold for the whole period unless the form asks for it separately.
- Results use standard published formulas and account only for the values entered above.
- Rounding is applied for display; the underlying calculation uses your full precision.
- Results are returned in the same units you enter, unless the tool states the output unit.
What it does not cover
- Work Converter produces a calculated result for reference and learning, not a certified or official measurement.
- Real-world outcomes differ when tolerances, rounding rules or local standards apply.
- Definitions and standards vary by region and change over time; verify the convention that applies to your case.
- Figures are only as accurate as the inputs you supply — check them before acting on the result.
- For work where the result carries real consequences, confirm it against an authoritative source.
