Examples
1
Consider that a smartphone charger delivers 15 watts (W) of power.
Convert this power output from watts to Milliwatts.
Answer
Given:
Power in Watts = 15 W
Converting Power from Watts to Milliwatts...
The formula to convert from Watts to Milliwatts is:
Power(Milliwatts) = Power(Watts) × 1e3
Substitute given Power(Watts) = 15 in the above formula.
Power(Milliwatts) = 15 × 1e3
Power(Milliwatts) = 15000
Therefore, 15 W is equal to 15000 mW.
2
Consider that a laptop uses 65 watts (W) of power while charging.
Convert this power usage from watts to Milliwatts.
Answer
Given:
Power in Watts = 65 W
Converting Power from Watts to Milliwatts...
The formula to convert from Watts to Milliwatts is:
Power(Milliwatts) = Power(Watts) × 1e3
Substitute given Power(Watts) = 65 in the above formula.
Power(Milliwatts) = 65 × 1e3
Power(Milliwatts) = 65000
Therefore, 65 W is equal to 65000 mW.

Watts
The watt (W) is the SI unit of power, defined as one joule per second. It is used to measure the rate of energy transfer and is commonly used in a wide range of applications, including electricity, mechanics, and heating.
Milliwatts
A milliwatt (mW) is a unit of power equal to one thousandth of a watt. It is often used in contexts where power levels are low, such as in electronics and communications.
