66 watts equals 66,000 milliwatts. This conversion shows how a power value in watts translates into milliwatts, which are smaller units. Since 1 watt equals 1,000 milliwatts, 66 watts becomes 66,000 mw.
To convert watts to milliwatts, you multiply the number of watts by 1,000, because there are one thousand milliwatts in a single watt. This simple multiplication helps to switch between the larger unit (watt) and the smaller (milliwatt), making measurements more precise for certain applications.

Conversion Formula
The conversion formula from watts to milliwatts is simple: multiply the watt value by 1,000. This works because 1 watt equals 1,000 milliwatts. For example, if you have 50 watts, you calculate 50 x 1000 = 50,000 mw. This ensures precise measurement for small power quantities, especially in electronics and engineering.
Conversion Example
- Convert 20 watts to mw:
- Multiply 20 by 1000.
- 20 x 1000 = 20,000 mw.
- Therefore, 20 watts equals 20,000 milliwatts.
- Convert 100 watts to mw:
- Multiply 100 by 1000.
- 100 x 1000 = 100,000 mw.
- So, 100 watts equals 100,000 milliwatts.
- Convert 5.5 watts to mw:
- Multiply 5.5 by 1000.
- 5.5 x 1000 = 5,500 mw.
- Thus, 5.5 watts equal 5,500 milliwatts.
- Convert 0.75 watts to mw:
- Multiply 0.75 by 1000.
- 0.75 x 1000 = 750 mw.
- So, 0.75 watts equals 750 milliwatts.
- Convert 200 watts to mw:
- Multiply 200 by 1000.
- 200 x 1000 = 200,000 mw.
- Therefore, 200 watts equals 200,000 milliwatts.

Conversion Definitions
Watts
Watts are units measuring power, representing the rate at which energy is used, transferred, or produced. It indicates how much work can be done over time, common in electrical, mechanical, and other energy-related contexts.
Milliwatt (mw)
Milliwatt is a small unit of power equal to one-thousandth of a watt, used when measuring very low power levels in electronics, communications, and precision instruments where small power quantities are necessary for accurate readings.
Conversion FAQs
Why is the multiplication factor 1000 used in watts to mw conversions?
This factor is used because by definition, 1 watt equals 1,000 milliwatts. Multiplying the number of watts by 1000 converts it into the smaller unit, providing more detailed measurement especially useful for small-scale power applications.
Can I convert watts to mw manually without calculator?
Yes, because the conversion involves a simple multiplication by 1000. For example, if you have 10 watts, you just add three zeros: 10,000 mw. This makes manual conversion straightforward, especially with whole numbers.
Are milliwatts used in specific industries or devices?
Yes, many electronic devices, communication systems, and sensor applications utilize milliwatts because they measure low power levels accurately, such as in wireless transmitters, medical devices, or precision measurements.
What is the significance of converting watts to milliwatts in real-world applications?
Converting to milliwatts allows for more precise power measurements in low-power devices, helps in designing circuits accurately, and ensures compatibility across different measurement scales, especially in tech and scientific fields.
