Calculator
How it works
La conversione da Watt a Kilowatt si ottiene dividendo il valore in Watt per 1000, in accordo con la definizione SI del prefisso "kilo" (k = 10³).
Assumptions and conditions
This calculation is valid under the following conditions:
- Grandezze scalari reali
- Unità SI standard
This calculation is valid when: Grandezze scalari reali; Unità SI standard.
This is an informational calculation (unit conversion or physical definition). The margin of error is negligible if inputs are correct.
All inputs and outputs use SI units. Convert any values in other unit systems before entering them.
Limitations
This calculation does not apply in the following cases:
- Solo conversione numerica, non considera perdite o rendimento
Solo conversione numerica, non considera perdite o rendimento
Referenced standards
No specific standard (definitional formula or fundamental physical principle).
Formula source: Definizione SI: 1 kW = 1000 W (BIPM SI Brochure 9a ed.)
Application examples
Dispositivo domestico 1.5 kW
Potenza tipica di un piccolo elettrodomestico (es. aspirapolvere, forno a microonde)
Motore industriale 75 kW
Potenza tipica di un motore elettrico industriale di media taglia
Frequently asked questions
What does the Watts to Kilowatts calculator compute?
Convert power from watts (W) to kilowatts (kW). Exact SI conversion: 1 kW = 1000 W.
When is this calculation valid?
This calculation is valid under the following conditions: Grandezze scalari reali; Unità SI standard.
When is this calculator not appropriate?
Solo conversione numerica, non considera perdite o rendimento
How accurate is the result?
This calculator implements the standard form of the formula. Accuracy depends on the quality of the inputs provided. Source: Definizione SI: 1 kW = 1000 W (BIPM SI Brochure 9a ed.).
What is the source of the formula?
Definizione SI: 1 kW = 1000 W (BIPM SI Brochure 9a ed.)
Which parameter has the greatest influence on the result?
"Potenza (W)" is the most influential parameter: a 10% change in this input produces approximately 10% change in "Potenza (kW)".
How does the result change under different conditions?
Comparison between "Reference conditions" and "Motore industriale 75 kW": Potenza (kW) [kW]: increases by 4900.0% (from 1.500 to 75.000).
Technical note
1 kW = 1000 W. Per convertire kW in W, moltiplicare per 1000.
Technical note
Esempi comuni: lampadina LED ~10 W = 0.01 kW; forno elettrico ~2000 W = 2 kW; motore industriale 75 kW = 75000 W.
Technical deep dive
About this calculator
Convert power from watts (W) to kilowatts (kW). Exact SI conversion: 1 kW = 1000 W.
Formula
kW = W / 1000
Validity conditions
This calculation is valid under the following conditions:
- Grandezze scalari reali
- Unità SI standard
Result sensitivity
The result varies significantly with changes in the following parameters:
- Potenza (W) [W]: linear sensitivity on "Potenza (kW)" (proportional, elasticity 1.00).
When this calculator does not apply
- Solo conversione numerica, non considera perdite o rendimento
Technical notes
- 1 kW = 1000 W. Per convertire kW in W, moltiplicare per 1000.
- Esempi comuni: lampadina LED ~10 W = 0.01 kW; forno elettrico ~2000 W = 2 kW; motore industriale 75 kW = 75000 W.
Technical analysis
Method: Convert power from watts (W) to kilowatts (kW). Exact SI conversion: 1 kW = 1000 W.
Reference result: Potenza (kW): 1.500 kW.
Sensitivity analysis
Elasticity: percentage change in output relative to percentage change in input (1.0 = linear).
| Input | Primary output | Elasticity | Relationship |
|---|---|---|---|
| Potenza (W) [W] | Potenza (kW) | 1.00 | linear |
Note: The result is particularly sensitive to "Potenza (W)" [W]: a 10% change produces approximately 10% change in "Potenza (kW)".
