How to Convert Watts to Milliwatts

One watt is equal to 1000 milliwatts:

1 W = 1000 mW

The power in milliwatts (P_mW) is calculated by multiplying the power in watts (P_W) by 1000:

P_mW = 1000 * P_W.

Example

Let’s say we have a power value of 5 watts P_(W). To convert it to milliwatts P_(mW), we can use the conversion formula:

P_(mW) = 1000 * P_(W)

Applying the formula, we get:

P_(mW) = 1000 * 5 = 5000 mW

So, 5 watts is equivalent to 5000 milliwatts.
