Educational explanation
Kilowatts to megawatts
Convert kW to MW when a solar string map, demand-letter appendix, or factory load list totals kilowatts but your interconnection study, ISO queue position, or generation portfolio slide quotes megawatts.
Kilowatts (kW) and megawatts (MW) measure the same power rate with SI prefixes: 1 MW = 1,000 kW on this site (Megawatt = 1,000,000 W; Kilowatt = 1,000 W). The conversion is exact decimal scaling.
MW = kW ÷ 1,000 · equivalently MW = kW × 0.001
Step-by-step conversion (worked example — 2,400 kW solar)
A commercial rooftop AC capacity is 2,400 kW DC:
- 2,400 ÷ 1,000 = 2.4 MW
- Interconnection paperwork often rounds to 2.4 MW nameplate while inverter limits may be slightly lower—document both.
Second worked example (750 kW factory peak)
A demand meter peaks at 750 kW:
- 750 ÷ 1,000 = 0.75 MW
Third worked example (12,500 kW wind)
A cluster totals 12,500 kW:
- 12,500 ÷ 1,000 = 12.5 MW
Quick mental estimate
Move the decimal three places left: 8,000 kW → 8 MW. Sub-megawatt plants read as decimals: 350 kW → 0.35 MW.
Kilowatt to megawatt conversion chart
| Kilowatts (kW) | Megawatts (MW) | Typical context |
|---|---|---|
| 1,000 kW | 1 MW | Definition anchor |
| 100 kW | 0.1 MW | Large commercial rooftop, microgrid |
| 500 kW | 0.5 MW | Factory peak, battery inverter block |
| 2,400 kW | 2.4 MW | Mid-size solar portfolio block |
| 5,000 kW | 5 MW | Community solar, small wind farm |
| 10,000 kW | 10 MW | Utility-scale project segment |
| 50,000 kW | 50 MW | Regional solar or wind site |
| 100,000 kW | 100 MW | Large generation asset headline |
Where kW → MW comes up
- Utility interconnection: Queue lists and ISO dashboards use MW; site aggregations start in kW.
- Renewables: Module and inverter maps sum kW; portfolio reporting uses MW.
- Data centers: Hall IT loads in kW; campus headlines in MW.
- Demand response: Event enrollments in kW; market clearing in MW.
Megawatts to kilowatts
Convert MW to kW when a generation asset or market bid lists megawatts but your panel schedule, battery PCS limit, or demand cap spreadsheet works in kilowatts.
Multiply megawatts by 1,000 to recover kilowatts.
kW = MW × 1,000
Step-by-step conversion (worked example)
A wind PPA nameplate is 3.2 MW:
- 3.2 × 1,000 = 3,200 kW

MW vs MWh, precision, and related converters
MW is power; MWh is energy (power × time). Convert kW↔MW only for nameplate or demand; use energy tools for production over hours.
Common mistakes
- Confusing MW with MWh—a 2 MW plant for 1 hour delivers 2 MWh.
- Summing AC and DC kW without labeling before converting to MW.
- Using 1024 instead of 1000 between kW and MW—SI prefixes here are decimal.

Frequently asked questions
How many megawatts is 1000 kilowatts?
1000 kW = 1 MW exactly on this site’s SI power scale.
What is the formula kW to MW?
MW = kW ÷ 1000.
What is the formula MW to kW?
kW = MW × 1000.
How do I convert 2400 kW to MW?
2400 ÷ 1000 = 2.4 MW.
How do I convert 3.2 MW to kW?
3.2 × 1000 = 3200 kW.
Is MW the same as MWh?
No. MW measures instantaneous power; MWh measures energy over time. Multiply MW by hours of operation to estimate MWh.
Why do utilities use MW instead of kW?
MW keeps generation and load numbers readable at grid scale (hundreds to thousands) without extra zeros.
Can I round-trip kW and MW?
Yes—divide by 1000 then multiply by 1000 to recover the original.
How does kW relate to watts?
1 kW = 1000 W. Convert watts to kW first if your source list mixes W and MW targets.
