8 watts (w) is equal to 8,000 milliwatts (mw).
The conversion from watts to milliwatts involves multiplying the value in watts by 1,000 because one watt equals one thousand milliwatts. So, 8 w times 1,000 gives 8,000 mw.

Conversion Formula
The formula to convert watts (w) to milliwatts (mw) is:
mW = W × 1000
This works because 1 watt equals 1000 milliwatts. When you multiply a value in watts by 1000, you scale it to milliwatts, which are smaller units.
For example, to convert 8 w to mw:
- Take the value in watts: 8 w
- Multiply by 1000: 8 × 1000 = 8000
- Result: 8000 mw
Conversion Example
- Convert 5 w to mw:
- Start with 5 watts
- Multiply by 1000: 5 × 1000 = 5000
- Answer: 5000 milliwatts
- Convert 12.7 w to mw:
- Take 12.7 watts
- Multiply by 1000: 12.7 × 1000 = 12700
- Result is 12700 milliwatts
- Convert 0.3 w to mw:
- Start value: 0.3 watts
- Multiply by 1000: 0.3 × 1000 = 300
- Thus, 300 milliwatts
- Convert 20 w to mw:
- 20 watts given
- 20 × 1000 = 20000
- Result: 20000 milliwatts

Conversion Definitions
W (Watt): A watt is a unit of power in the International System of Units, measuring the rate of energy transfer. One watt equals one joule per second. It quantifies how much energy is used or produced over time in electrical circuits and mechanical systems.
mW (Milliwatt): A milliwatt is one-thousandth of a watt, used to measure smaller power amounts. It is equal to 0.001 watts and is common in low-power electronic devices, like radios or LEDs, where precise, smaller units of power are needed.
Conversion FAQs
Can the watt to milliwatt conversion handle decimal values?
Yes, the conversion works the same for decimal values. You multiply the decimal watt value by 1000 to get milliwatts, so 0.75 w becomes 750 mw. Decimals just require careful multiplication to keep accuracy.
Is it possible to convert milliwatts back to watts?
Definitely, to convert milliwatts to watts divide the milliwatt value by 1000. For example, 5000 mw divided by 1000 results in 5 w. This is just the reverse of multiplying by 1000.
Does this conversion apply to AC and DC power?
The conversion purely relates to the unit scale, not power type. Whether AC or DC, 1 watt equals 1000 milliwatts. However, power calculations in AC circuits might involve other factors like power factor, but the unit conversion remains the same.
Are watts and milliwatts used for measuring the same things?
Watts and milliwatts both measure power but used at different scales. Watts are for larger power levels, while milliwatts are useful for low-power electronics. They express the same concept but fit different measurement ranges.
What happens if a negative watt value is converted?
Negative watts indicate power flow direction or loss. When converting to milliwatts, the negative value is preserved and multiplied by 1000, reflecting the same negative power magnitude in smaller units.
