About

Power generation and consumption specs often alternate between Megawatts (for grid-level capacity) and Kilowatts (for facility-level loads). For instance, a wind turbine might be rated in MW, but the transformers or commercial heaters it powers are rated in kW. Miscalculation by a factor of 1,000 here is a common but disastrous "order of magnitude" error in electrical planning.

This utility offers a rapid, lag-free conversion focused on readability. It is optimized for 3G connections, ensuring that field engineers can access it instantly on site. The output explicitly handles comma separation for thousands (e.g., 10,000 kW), making it easier to transcribe numbers into reports without counting zeros manually.

Formulas

The prefix "Mega" (M) represents 10⁶, while "Kilo" (k) represents 10³. Therefore, the conversion factor is exactly 1,000.

P_kW = P_MW × 1,000

No complex calculus is required, but ensuring the input is correctly identified as MW (and not MWh) is crucial for validity.

Frequently Asked Questions

MW (Megawatt) is a unit of Power (instantaneous rate of energy use). MWh (Megawatt-hour) is a unit of Energy (total amount used over time). This calculator only converts Power (MW to kW).

There are 5,000 kilowatts in 5 Megawatts. You simply multiply the MW value by 1,000.

Yes. The Watt is defined as 1 Joule per second regardless of whether the current is Alternating (AC) or Direct (DC). The conversion ratio of 1,000 remains constant.
